How to do rice transplanting? What are the management techniques of rice transplanting during the tr

When transplanting rice, we must pay attention to the quality of the soil, but also pay attention to the transplanting skills, and we must pay attention to the depth. These management techniques are to manage the growth of seedlings, as well as pay attention to the depth of seedlings, pay attention to the fertilization of seedlings, but also pay attention to soil conditions, but also pay attention to soil moisture.

It is necessary to choose the right size of rice for transplantation, pay attention to the height of rice seedlings, pay attention to the amount of water when transplanting, and pay attention to the situation of fertilizer in order to grow better.

It is best to manage in groups, but also to prepare for transplanting, to pay attention to the fertility of the soil, but also to ensure the moisture of the soil.

When transplanting rice, we must grasp the appropriate time, and we must pay attention to maintaining sufficient water when transplanting rice with rice transplanting, so that the survival rate is relatively high.

It takes about a month, and at this stage of growth, you must fertilize every day, so as to ensure that the rice grows well, and to ensure the adequacy of water, and the surrounding temperature should also be controlled.

2. Soaking seeds to promote germination: There are two methods of soaking, one is soaking seeds after coating, and the other is soaking seeds directly in the jar, both methods can be, the effect is the same, that is to say, we often use soaking prochloraz, soaking effect is not good, you can find other soaking agents instead. The soaking time is generally 7 days, the temperature is required to be above 11 degrees, and a trough should be stirred from time to time to make the seeds evenly absorb water, and the outside temperature is higher, so stirring several times can also make the temperature the same, of course, there is no stirring medicine.

Soaking seeds, the husk is dark in color, the seeds are transparent, placed in the sun, you can see white, with twisted hands, there is no hard core. The germination temperature of rice seeds is 30 degrees, 25 degrees after germination contact white, the length is not more than 2 mm, and then air germination begins, air excess moisture, especially breeding line machine, no air germination, breeding does not germinate.

3 Seedbed management: From sowing to the first leaf, the temperature is up to 7 days and as low as 9 days. During this period, the temperature of the greenhouse should not exceed 32 degrees.

We dig a 30 cm by 30 cm hole in the plastic roof every 5 meters, and the morning moisture is in the shed. After the first leaves, control the shedding temperature between 22 degrees and 25 degrees, and the maximum is not more than 28 degrees, start the ventilation cultivation of seedlings, and try to keep the seedbed dry. After the second leaf, the temperature of the fallen leaves of the control is 20 22 degrees, and the maximum is not more than 25 degrees.

Start large ventilation, open canopy ventilation on cloudy or rainy days.

4 control and regulation of acidity: seedlings first in a leaf to adjust acidity, and then spray, the standard of adjusting acidity is my home 100 square meters 3 catties of acid, acidic seedbed and the rest of the soil after the sieve evenly stirred, through cations to the seedlings, immediately watered, the seedbed thorough but can not run, every 7-10 days and then watered, usually with the pH value test paper under the pH value of the bed. Prophylactic medications can also be taken every 7 to 10 days, preferably after taking acidic medications.

The above is the key to ensure timely transplanting of rice, as long as there is no disease, farmers will not like it, early transplanting, every farmer is very worried, seedlings will be sick in bed for a long time, only very early transplanting.

Generally, it is okay in about 20 days, and the time should not be too early, because it is not easy to survive too early, and the roots are not very strong, so it is better to choose a longer time.

Under normal circumstances, seedlings can be transplanted at 33-55 days. However, we can also choose the best transplanting time according to the type of seedlings and the climate in which they are raised. Rice seedlings can generally be transplanted within 55 days, of which 40 days and 45 days are the best.

Rice seedlings are generally transplanted in about 3-7 days, at this time the roots are in the early stage of growth, can be better transplanted, and can be changed to the seedling field, but also can adapt to growth.

It is generally best transplanted at 30 days, because by 30 days, the rice seedlings have grown almost enough and have absorbed enough nutrients.

Mechanical transplanting, manual transplanting. Mechanical transplanting is divided into two kinds due to different power modes: semi-mechanized manual transplanting machine transplanting machine transplanting with artificial power; Machine-powered power rice transplanter.

The efficiency of the mechanical rice transplanter is high, the manual rice transplanter is 2 3 times faster than the manual hand transplanting, and the power rice transplanter is more than 20 times more efficient than the manual hand transplanting.

We must master the skills, we must do a good job in seed and seedling raising, we must prevent pests and diseases, we must pay attention to the depth of planting, we must supplement fertilizers in time, and we should also use pesticides in time.

The specific steps of transplanting are to first dig a pit at the transplanting location, then dig out the rice, and then quickly put it into another pit, and then compact the soil by hand, so that the transplanting steps are completed.

First of all, we should choose fertile soil, but also should be watered and fertilized in time, strengthen water and fertilizer management, ensure sufficient light, do a good job of drainage and ventilation, and then learn professional transplanting techniques, the process of transplanting must be timely, so as to improve the survival rate.

In the north and south of China, the gap between rice seedling methods in the north and south of the rice area is relatively large, water seedlings, dry seedlings, cast-in-place beam plastic film covering seedlings, cast-in-place beams without anti-cloth mulch film covering seedlings, non-anti-cloth agricultural film flattening and covering seedlings, large-scale seedlings, seedling methods are also divided into suitable machine insertion, suitable seedling throwing and its live broadcast room, etc., the specifications of seedling transplantation are not the same. Artificial transplanting is divided into seedling transplanting, medium seedling transplanting, and large seedling transplanting. Seedling transplanting is leaf, medium seedling transplanting is 4-5 leaves, and large seedling transplanting is 5-6 leaves.

Artificially transplanted seedlings should understand the problem of pulling seedlings, stipulating that the seedling height is appropriately higher, and can be tied, at the same time, the seedlings are old and healthy, and the seedlings are not easy to break when pulling seedlings, so as to reduce the regreening period.

The key to the management method of complete leaf elongation is to manipulate the height of the first petiole and the number of nodes and roots of the sheath leaf to the specification of the seedlings. The temperature of the first height of the seedling is controlled at 22 28 at 1cm under the leaf, and the minimum temperature is not less than 10. Moisture management methods in addition to the seedling stage of the dry place water and moisturizing, generally less or no watering, so that the seedling stage to maintain the dry breeding situation, prohibit the use of water below 15 to water seedlings, resolutely put an end to frostbite damage seedlings.

The key to management methods: promote root tillering, control leaf stems, and cultivate standardized seedlings. Moisture Management Methods:

Strictly implement the "three-look watering" specification and water immediately to avoid the withering of seedlings. It is necessary to carefully analyze the growth and development characteristics of seedlings at this stage, and specifically guide farmers to improve the seedlings according to the situation, so as to replenish water and moisturize and supplement fertilizer (vegetarian).

The main content of disease prevention and insecticide is the cultivation of paddy fields, and the cultivation of strong seedlings is diligent. For the paddy field that is dry and sharp around the afternoon, it is stipulated that the permeability is made up before and after dusk, and if the microbial potassium is not used when throwing the seedlings, 200ml of microbial potassium fertilizer is used for the seedling stage of the 1 mu field. Improve the quality of seedlings, manipulate pest damage, and at the same time, seedlings live quickly after planting and head early.

According to the leaf age and seedling age, the transplanting is guaranteed at the appropriate time, and the seedling age of dry breeding and sparse planting is mastered in more than 55 days; Strive to basically complete it by May 25. Comprehensively promote the planting technology of accurate quantitative analysis of yield increase, pay attention to improving the panicle rate of stem tillering, and cultivate people with high special effect yield increase after panicle.

The main measures are to strictly control the basic seedlings, reduce the starting point of the population, manipulate the seedlings in the peak period, reduce the ineffective tillering, harmonize the association of ears and grains, and further improve the yield. It is stipulated that the basic seedlings of 1 mu of dry breeding and sparse planting are about 10,000 yuan, the row spacing is expanded to more than 20cm, and the plant spacing is maintained at 16cm. When transporting seedlings to the field, water should be injected, but do not submerge the seedlings, generally to 2 3 of the seedlings.

Promote the growth and development of new roots of seedlings, and integrate into the living environment of the field as soon as possible. Moisture management methods for paddy fields play an important role in improving the survival rate of seedlings and their regreening time. After transplanting rice seedlings, for various reasons, it is inevitable that there will be falling seedlings, so remember to go to the field to observe the seedlings, if there are some fallen seedlings, the seedlings must be replenished, in order to ensure the relative density of rice seedlings in the field and the number of seedlings, in order to ensure the production.

About 30 days is the most suitable, be sure to pay attention to the condition of the soil, you need to pay attention to the temperature, preferably around 25.

Transplanting is most suitable at 30 days, when the rice seedlings grow particularly tall and have particularly good absorption.

It is better to control it in about 20 days. At this time, the state of the seedlings is very stable and can be well determined.

30 days is the best, when the condition of the seedlings is relatively stable, and the distance can be well controlled.

1. Before planting rice, soak the seeds, soak the grain seeds in water for 2-3 days, and then fish them out when they emerge small white buds. The soaking time is determined by the temperature, with a short soaking time for high temperatures and a long soaking time for low temperatures.

2. Put the white buds in the bamboo basket and lay them out, and then cover them tightly with plastic film, and when they grow longer white buds, they can be raised in the rice field.

3. Before raising seedlings, the paddy field should be raked, and there must be a lot of water in the paddy field.

4. About half a month after the seedlings are raised, when the seedlings grow to about 10 cm, they can be transplanted.

5. Before transplanting, the paddy field should be stored with water, ploughed, harrowed and other related work, and the seedlings and seedlings can be pulled and planted after the field work is completed.

Rice planting time

1. Early rice. It is usually sown at the end of March and the beginning of April, and the harvest season is in mid to late July. When the climate temperature is stable at about 13 degrees, early rice sowing can begin, for example, the Yangtze River basin is best sown from late March to early April.

It is generally cultivated earlier and matures early, with a growth period of about 90-120 days.

The areas suitable for planting early rice are mainly distributed in the south, such as Hunan, Guangxi, Guangdong and other places. The rice produced by early rice is also called early can or early rice, and the taste of early rice is usually crossed, and it is often used for industrial grain or reserve grain.

2. Medium rice. It is usually sown in early April and late May, and the harvest season is in mid to late September. Medium rice is suitable for planting in most areas, and its development will vary greatly because of the different regions and climates, the general growth period is about 120-150 days, the seedling raising method is mainly based on moist seedling fields, two stages of seedling raising, the taste of middle rice is the best early rice and late rice.

The areas suitable for planting medium rice are mainly distributed in most areas of China except Guangdong, Qinghai and Hainan, and the main production areas are: Hunan, Jiangsu, Sichuan, Heilongjiang, Hubei, Yunnan, Chongqing, etc.

3. Late rice. It is usually sown in mid to late June, and the harvest season is mid to early October. It has a long growth period and a late maturity period, with a growth period of about 150-170 days.

It does not taste as good as medium rice, but it is better than early rice. The suitable planting area of late rice is similar to that of early rice, and it is mainly planted in the south.

Rice can generally be transplanted in about 30 days. It depends on the weather conditions and the way the seedlings are raised. The seedling age of rice is generally 28 to 30 days. Rice is generally transplanted in about 30 to 35 days after sowing, and the seedling age of early rice regeneration rice is longer.

Apply enough organic fertilizer. According to the requirements of "four types in one" formula fertilization, when cultivating flat fields, apply enough organic fertilizer, generally based on farmhouse fertilizer, such as cake fertilizer, or 40 50 kg of organic fertilizer sold on the market, 10 20 kg of superphosphate or diamine phosphate, and at the same time, 2 kg of pole power can be applied per mu of paddy field, and the pole power element has the function of dissolving phosphorus and potassium, and the power is strong, the fertilizer effect is lasting and improving the soil structure, and the effect of improving fertilizer utilization rate is not necessary, because the seedlings that have just been planted have no ability to absorb fertilizer. At the same time, it can not stand the soaking of high concentration nitrogen fertilizer, otherwise it is easy to cause the phenomenon of slow seedlings and no trees.

Scientific top dressing management. According to the technical requirements of the "four types in one" formula, topdressing should be applied 5 10 kg of urea and potassium fertilizer only after 4 5 days of planting, that is, when the seedlings begin to take root, and mixed with herbicides to spread, which is conducive to the rapid living of rice seedlings and the effect of cultivating and weeding. 2 3 weeks and then apply 10 kg of urea, 15 kg of potassium fertilizer or compound fertilizer, which is conducive to the rapid tillering of rice and the effect of heading, which can be more than 5 10 rice ears than the traditional rice fertilization method, and the principle of "four types in one" formula fertilization to increase yield is in it.

During the booting to heading period, you can use Luoxiao royal liquid with nails? K bactericide mixed spraying, once a week, can not only effectively control rice sheath blight, Aspergillus and other diseases, but also can effectively prevent rice straw lodging and promote the function of full and early maturity of grains, and other pests and diseases can be controlled according to conventional management methods.

1.Amount of fertilizer. Tillering fertilizer is mainly nitrogen fertilizer, which generally accounts for 20% to 30% of the entire growth period.

Urea 6 10 kg mu, or ammonium sulfate 15 20 kg mu. Generally, plots with high soil fertility can be applied less, plots with low soil fertility can be applied more, strong seedlings can be planted early can be applied less, and weak seedlings can be planted late.

2.Fertilization method. First, it should be applied early, because the fertilizer effect of nitrogen fertilizer is slow, it takes a period of time to take effect after fertilization, so tillering fertilizer should be applied early, and it should be applied immediately after returning to green.

The second is to look at the seedling fertilization, first use 80% of the tillering fertilizer to spread evenly in the whole field, and the remaining 20% depends on the growth of the field. In this way, the growth potential of the whole field is basically the same. After fertilization, the field should retain a water layer, which cannot be drained, and irrigated after it dries naturally.
