What should I do if the rice is lodging? Should I help it?

If the root of the rice is down, in other words, the stem of the rice is not broken, but the whole rice is poured from the root, it can still be supported, and after the root is lifted, the whole rice is lifted up, and after straightening, the root of the rice is stepped on with the foot, in that case, if there is no flood damage before the rice harvest, then it will basically not harm the rice harvest, but if it is destroyed by flood disaster before the harvest.

Then it may fall short, and the rice that has been poured again will not be able to be corrected! There are many reasons for rice lodging, which are not only related to high winds and heavy rains, but also due to the poor lodging resistance of rice. The species are not lodging resistant, the fertilizer and water management is unreasonable, the planting relative density is too large, the natural ventilation and light transmittance conditions in the field are poor, and the diseases and pests are more serious, so if the rice is resistant to lodging, the measures can be taken to adopt lodging resistant species, reasonable dense planting, balanced fertilization, reasonable irrigation, and early prevention of pests and diseases.

When the rice is ripe, the ears are rounded, the weight increases, of course, it is loose, and it is very easy to fall seedlings. There are many reasons for seedling failure, including natural factors and cultivation techniques. Regardless of the reason for the seedlings, the rice seedlings are brittle and soft and not malleable, and have already been damaged, which is not conducive to the transportation of nutrients and the natural maturity of rice.

When the rice lodging is down, it has not been grouted yet, and it should be lifted up immediately. Otherwise, it will be soaked in water and rotten, resulting in extinction. Rice seedlings are produced at the grain-filling stage, depending on the seedling situation.

If the ears of rice are not submerged by water, there is no need to support them. The main reason is that in the process of lifting up, the rice plants at this time are very brittle, resulting in damage to the rice, and even breakage, due to small losses. If the rice seedlings fall before harvesting, they should be lifted up at this time to avoid the budding of the rice, which will reduce the quality and reduce the yield.

Rice slight lodging, can not be held up to tie the handle, heavy lodging can be tied into a small handful with a rope, to avoid the harvest, rice light lodging is usually backward lodging, about 3-5 days, the cob will be naturally cocked under the automatic adjustment of the plant, at this time if the rice, it will artificially destroy the rice ear, increase the loss, heavy lodging if the lodging area is small, not completely touching the ground, can be tied up with a rope.

If the rice is upside down, it should be helped, if it is not helped, it will affect the yield, and the rice with serious lodging can be tied, and if the lodging is not serious, it can be tied with weeds.

It is necessary to prevent the germination of rice. Rice grains absorb more than 24% of the water to meet the water conditions required for germination, 18 or more, the higher the temperature, the faster the germination, especially in the summer when the high temperature continues, if the rice lodging, and then encounter continuous rainy or humid environment, it is easy to germinate. If it is not ripe, it is necessary to drain the stagnant water in the field, first, to prevent the rice from rotting, and secondly, to prevent the rice from germinating with water.

After draining the water, wait for the rice to mature and harvest it with a harvester.

It is more powerful: or there is more water in the field, and the machine cannot harvest, and the last resort can only be harvested manually. After the rice is harvested by hand, it is placed on the concrete floor, and the rice is crushed by a tractor or other vehicle, and then dried in the sun.

If the area of the paddy field is not very large, you can manually use a sickle to cut the rice trapped in the silt, these grains are generally very wet, and there is a lot of silt on them, after harvesting, they are generally dried separately, and they cannot be sold, leaving chickens, ducks and geese as rations. If the planting area is relatively large, <>

The current rice harvester can already harvest lodging rice, even if the rice lodging is serious, or the rice is lying directly in the ground, it can also be harvested. However, after harvesting, the cleanliness of the rice will decrease, and the cost of harvesting will increase if you ask the harvester to harvest the lodging rice. It is to prevent and control pests and diseases, rice blast, sheath blight, ear neck blast, two chemical borers, etc. are one of the reasons for rice lodging, do a good job in pest control, reduce the possibility of lodging.

Generally, the water should be shallow at the seedling stage, or there is no water in the field. Two benefits, the ground temperature rises quickly, and the seedlings are strong; Second, there is less water at the seedling stage, and the root internodes are short, thick and firm, which has a certain effect on preventing lodging. If there is a windy day, try to release water in the field, there is water in the field, and the rice is easy to lodging; The technology in the process of rice seedling raising is not standardized, such as too dense sowing, improper fertilizer and water management, resulting in slender seedlings without tillers, resulting in the whole group is not robust.

In addition, when farmers plant seedlings, they "plant trees indiscriminately", and the ventilation and light transmission of rice after closed rows are poor, which is not conducive to the healthy growth of rice and is easy to lodging.

It should be harvested as soon as possible, and harvesting rice as soon as possible can reduce some losses.

The rice lodging is about to be harvested, so leave it alone at this time, after all, it is almost harvested, and many, many rice are already ripe.

It is impossible to straighten the lodging of rice, and in order to avoid the rice germination caused by the lodging of the rice in the water, it should be harvested as soon as possible.

In this case, I think the harvest should be delayed, the nutrient solution should be replenished in time, and the phosphorus and nitrogen fertilizers should also be selected for fertilization, and pesticides should also be sprayed.

First of all, choose varieties with strong lodging resistance. Secondly, it is necessary to plant reasonably densely, according to the tillering characteristics of different varieties and soil fertility and fertilizer level, determine the appropriate transplanting density, too dense transplanting will be too large, easy to lead to lodging, too thin transplanting group is insufficient, and is not conducive to high yield. Third, it is necessary to apply fertilizer reasonably, apply nitrogen fertilizer appropriately, increase phosphorus and potassium fertilizer and organic fertilizer, and apply fertilizer scientifically and reasonably according to the law of rice fertilizer demand and soil fertilizer supply capacity, so that nitrogen, phosphorus, potassium fertilizer and organic fertilizer can be applied together to enhance lodging resistance.

Fourth, to achieve reasonable water management, shallow water planting, inch water live trees, to reach the expected stem tiller number index to carry out shelving, not only to control ineffective tillering, but also to improve lodging resistance. During the grouting stage, the dry and wet water is alternated to achieve root and leaf protection and improve the lodging resistance. Fifth, it is necessary to pay attention to the prevention and control of rice blast, sheath blight, rice planthoppers, rice borers, etc., and prevent lodging caused by pests and diseases.

Foliar silicon fertilizer can be applied to rice rationally.

Effect of foliar silicon fertilizer on rice:

1. Cadmium foliar silicon fertilizer can enhance the mechanical strength of crop straw, make the stem straight, and improve the lodging resistance of crops by 80%.

2. Silicon fertilizer can enhance the aeration of crops, prevent root rot and premature aging, and play an important role in the prevention and control of crop root rot.

3. Silicon fertilizer can well regulate the balanced absorption of different nutrients such as nitrogen, phosphorus and potassium by crops, adjust the fertilizer utilization rate, and make effective use of nutrients, which is called"Plant-based regulatory fertilizers"。

4. Silicon fertilizer can effectively inhibit the water transpiration of plant leaves, and after applying silicon fertilizer, the silicized cells produced can effectively regulate the opening and closing of leaf stomata, tap water transpiration, and enhance the stress resistance of crops.

5. Silicon fertilizer can improve crop yield, enhance photosynthesis and increase chlorophyll content, apply silicon fertilizer to effectively improve rice yield, promote rice photosynthesis, enhance root development and effective utilization of nutrient powder.

6. Cadmium foliar silicon fertilizer can inhibit the absorption of heavy metals by crops, effectively reduce the content of heavy metals in crops, and reduce its pollution to below the national safety standards.

7. Silicon fertilizer is a high-quality fertilizer, which can improve the quality of crops to a certain extent.

8. Silicon fertilizer can enhance the resistance of crops to pests and diseases, and can reduce the impact of pests and diseases on crops.

Instructions for the use of cadmium foliar silicon fertilizer in rice:

Spraying time: depending on the degree of cultivated land pollution, 1-2 sprays of foliar fertilizer can be applied from the vigorous tillering period of rice and wheat to the heading period; Choose a sunny or cloudy day to spray around 4 p.m.

Dosage description: about 1 bottle of cadmium desnoryl per mu each time, a bottle of 500 ml; Artificial spraying needs to be mixed with water 50-100 times; UAV spraying with water 5-10 times; Foliar sprays are applied. Based on the principle of foliar dripping, the number of spraying should be increased according to the degree of pollution of cultivated land.

Hope it helps

OK.

Light lodging: light lodging rice should not be supported by rice tie handle, the reason is that the rice plant is usually homeopathic backward lodging, its rice ear, spike stem node, inverted one leaf, inverted two leaves are mostly exposed to the surface, after 3-5 days, the leaves, cob will be naturally warped under the automatic adjustment of the rice plant, the lodging phenomenon is not serious in the plot of the rice plant has a more mega reduction of the ability of automatic adjustment. Pat Pei.

If the rice is tiddled after lodging, the natural distribution of rice ears, ears and stems and leaves will be artificially damaged, resulting in aggravated mechanical damage and further increasing losses.

Rice precautions.

During the planting period, the water layer has been maintained, so that the soil permeability is poor, and the root system of rice plants is underdeveloped (easy to poison, weak root strength).

Prolonged water in the field will also cause the plants to be too tall, the stalks will become softer, and the lodging resistance will be reduced, and lodging will occur once it encounters the invasion of external forces.

Disease infestation: Rice is attacked by diseases, such as sheath blight, which is prone to lodging.

Be sure to choose the right harvest time, you should choose the right insecticide or herbicide according to the type of pests and diseases, you must avoid the tape measure to avoid being blown by the sea breeze, you must do a good job of soil drainage, you must cut off the inverted early in time, and then put it next to it for threshing, and then put it in the sun to expose to the sun.

The best way is to harvest the hail of the bush as soon as possible, otherwise it is easy to lead to a decrease in yield, we must pay attention to ventilation, pay attention to light transmittance, and you can tiller the plants with cherry blossoms.

It is necessary to quickly drain the water in the field, slow down the lodging, and harvest in time to reduce losses when the weather is fine; Reverse harvesting can be employed.

Once the rice has fallen, do not hold the rice stick as the fallen rice usually grows according to the trend. If the flustered rice, the knots on the flustered trunk, and the rice fall slightly, they do not need to be tied with ropes. Due to the automatic adjustment of the rice plant, the leaves and spike holes will automatically tilt upwards.

For a serious stay, the bala must be used as a ransom. Those who are strict must fasten the rings so that no rotten seeds will germinate. The last two leaves were basically exposed to less heavily accommodated fields, and the rice plants were more self-adjusting.

However, after rice adaptation, the natural distribution sequence of panicles, ears and leaves will be disrupted, affecting photosynthesis, aggravating mechanical damage and resulting in loss of income. Due to natural disasters such as strong winds and heavy rains, 3 5 days after the rice imitation bush plants move in, blowing rice mud to form a large area of automatic feeding, which will affect the rice that can not be eared after the wax maturity period, and in the yellow maturity period, if the mature varieties have 95% of the grain filling, continuous rainfall and drainage difficulties, they can be collected in advance. Conditioning mainly affects the general aesthetics and fruit fixation.

After adjustment, the MS leaves bent together, which seriously affected the formation of rice photosynthetic products, increased wrinkle grains, decreased 1000-grain weight, and led to the decline of rice yield and quality. In the case of jujube rain in the lower stage of the host, the ears cannot be raised after being collected, and this ring is suitable to prevent the germination and forming of rice. If Huang Dan finds that there is a lodging, the handle can be manually lifted to minimize the adverse effects. Rice storage is the result of a combination of factors, and it is inevitable to rely on a certain measure to dismantle it.

Focus on variety selection, planting density and maturity.

After lodging, if the early maturing variety reaches 95, there are two common types: one is basic adaptation and the other is broken stem adaptation. The first is the main phenomenon of rice lodging.

This TEM accommodation has little impact on revenue and cannot be handled. It is not appropriate to keep the rice bar to hold a small amount of rice. Although persistent rainfall and rice adaptation are associated with heavy rain weather, they are mainly due to poor rice resistance.

This is too. Keeping rice sticks after accommodation artificially disrupts the natural distribution of rice ears, ear stems and leaves, making mechanical water loss difficult and allowing for early harvesting.

First, if we want to know the methods of preventing rice lodging, we must first know what are the reasons for the occurrence of rice lodging. So what causes rice lodging?

1.The density is too high and the ventilation is not good.

The density of transplanting seedlings is too large, the plant spacing is too small, the number of tillering plants is not controlled, the mentality of cherishing seedlings is serious, the density of the whole field is large, the number of plants is large, and the ventilation is not good, which causes a large area of lodging.

2.The transplanting is too shallow.

Such rice has poor root extension, underdeveloped root system, and poor grip firmness.

3.Do not dry the field, and apply excessive nitrogen fertilizer.

Excessive application of nitrogen fertilizer, we are reluctant to dry the field, so that the root system is underdeveloped, the number of new roots is small, the root is shallow, the rice internode is too long, the surface of rice grows vigorously, but the stem wall is too thin, the stem tissue is not tight, the rice is too high and the lodging resistance is low.

4.Aquifer management.

In the whole rice growth period, if the rice field always maintains a water layer, the soil permeability is not good, the root system is not developed, it is easy to be poisoned, the root strength is weak, there is water for a long time, the rice growth is too high, the stalk is soft, the lodging resistance of rice is reduced, and it is easy to lodging if it is invaded by external forces.

5.Pests and diseases, such as sheath blight, form lodging.

2. Preventive measures for rice lodging.

1.Resistant varieties were selected, and rice varieties with thick stems, short plant shapes and strong lodging resistance were selected for reasonable dense planting. Reasonable dense planting, coordination of individual and group relations, planting density is too large, lodging opportunities are also more, especially in direct seeding paddy fields, it is necessary to grasp the sowing amount and the number of tillering seedlings in the field.

2.Do a good job in water and fertilizer management, prevent diseases, insects and weeds, apply reasonable fertilization, apply more phosphorus, potassium fertilizer, biological fertilizer, and silicon fertilizer to enhance rice lodging resistance. Nitrogen fertilizer should not be consumed too much or too late to avoid lodging.

Timely ditching and drainage of the field, deep mud field, rotten mud field more sun, early sun, heavy sun, sun to the foot does not fall into the mud, the field cracks for the degree. The shallow sand tin is diligent, lightly sunned, and left the water many times. We should do a good job in the comprehensive prevention and control of diseases, insects and weeds, and put an end to disasters caused by pests.

3.To strengthen the management of rice growth period and do a good job in growth regulation, the main thing is to shorten the length of stem internodes, reduce the center of gravity of rice, make the stem strong, develop the root system, and improve the lodging resistance.

4.In case of bad weather, when the rainstorm comes, it is necessary to open a ditch to drain the water, so that the field mud does not soften, and often observe the dynamics. Once there is a lodging, you can be artificially helped up, 2 3 clumps and tied with straw to stabilize the waist.

3. First aid measures for rice lodging.

1.Timely ditching and drainage of light field resting have a positive effect on slowing down the spread of sheath blight, prolonging the functional period of leaves, promoting grain filling, and preventing panicle germination and stem rot.

2.For lightly lodging rice should not be supported by rice tie because the lodging rice plants are generally homeopathic backward lodging, rice ears, spike stem nodes and inverted one leaf, inverted two leaves are basically exposed on the surface, 3 5 days after lodging, due to the automatic adjustment of rice plants, the leaves and cobs will be automatically cocked, especially in the fields where the lodging is not too serious, the rice plant automatic adjustment ability is stronger. However, after lodging, the natural distribution of rice ears, ear stems and leaves will be artificially destroyed, which will aggravate the mechanical damage and cause more serious lodging loss.
