What fertilizer is better for rice? What to look out for?

Thank you for the invitation, this question is divided into two parts, one is the law of rice fertilizer demand, although there are differences in cultivation methods and rice varieties, but the growth nature of rice has not changed, but the amount of fertilizer and time will be somewhat different; Second, what fertilizer is better to use? How to choose a good fertilizer?

First of all, we will talk about the law of fertilizer demand of rice: rice is one of the crops that need more fertilizer, generally every 100 kg of rice needs nitrogen (N) kg, phosphorus (P2O5) kg, potassium (K2O) kg, and the proportion of nitrogen, phosphorus and potassium fertilizer demand is about 2 1 3. In addition, silicon and zinc micro-fertilizers had a great impact on the yield and quality of rice.

The application of silicon and zinc fertilizers was more obvious in newly modified paddy fields, acidic soils, and cold-soaked fields.

The nitrogen uptake of rice peaked at the peak tillering stage and heading and flowering stage. There was little difference in the uptake of phosphorus in rice at different growth stages, and the period with the largest uptake was from tillering to spikelet differentiation. The potassium uptake in rice was mainly from panicle differentiation to heading and flowering, followed by tillering to panicle differentiation.

Second, what fertilizer is better? The principle of rice fertilization should be organic fertilizer, phosphorus fertilizer as base fertilizer, compound fertilizer plus calcium, magnesium and phosphorus fertilizer, potassium fertilizer mainly as tillering fertilizer, nitrogen fertilizer using multiple uniform application, special attention to good buds, strong seed fertilizer, in the full ear at the same time, attack the large spike and large grains. In the early stage of tillering, pay attention to the application of silicon-zinc fertilizer, such as Wuhan Puruifeng's Mengfa Dou (silicon-zinc fertilizer), to promote tillering, lodging resistance, and increase yield.

In the selection of fertilizers, it is recommended not to be greedy for cheap, choose regular manufacturers and brands of fertilizers, good fertilizers, fertilizer utilization rate is high, that is, the same application rate, good brand fertilizer effect is better and longer! In addition, now the soil testing formula is based on the measurement of the content of nitrogen, phosphorus, potassium, silicon, zinc and other elements in the field, what is lacking and how much to make up, aiming to improve the utilization rate of fertilizer, relatively speaking, the soil testing formula fertilizer is better.

Rice is a silicon-loving crop, and the spraying of foliar silica fertilizer can effectively improve the yield of rice and improve the ability of rice to resist lodging, diseases and pests.

Instructions for use of foliar silicon fertilizer:

Spraying time: depending on the degree of cultivated land pollution, you can choose to spray cadmium foliar fertilizer 1-2 times 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.

Precautions for the use of foliar fertilizer in rice:

1. When using, it should be used now, and the prepared cadmium foliar fertilizer should not be stored for a long time.

2. Foliar spraying is required with a sprayer with good atomization effect.

3. Do not use it in rainy days, if it rains 24 hours after spraying, it needs to be supplemented. Do not spray when exposed to the sun to avoid burning the leaves.

4. Do not spray with pesticides or other foliar fertilizers, so as not to affect the effect.

5. Store in a ventilated and cool place. When spraying, you need to wear gloves, masks, and work clothes to prevent the entrance from entering the eyes, and splashing ** should be quickly cleaned with water.

6. Keep out of reach of children to prevent children from eating by mistake.

Hope it helps

Rice is a relatively wide range of food in China's planting area, at present, rice needs a lot of fertilization in planting, and it is indispensable, fertilization is carried out when rice is planted, which is conducive to the development of rice roots, strong growth, and improve its ability to resist stress. Now there are many fertilizers suitable for rice on the market, but the seedling fertilization of rice, in principle, is the use of organic fertilizer, organic and inorganic combination, most of the rural urea fertilizer as the main nitrogen fertilizer for rice planting, the fertilizer containing nitrogen is indeed conducive to improving soil moisture and nutrients, more conducive to rice planting, but only using one fertilizer is not very suitable for rice planting. <>

Basal fertilizer as an organic deficiency fertilizer, when planting rice, 50% to 60% of the rice fertilizer amount is nitrogen and phosphorus, potassium, etc., these chemical components come from the soil, so the soil has a great influence on rice planting, need to apply an appropriate amount of fertilizer according to the situation, each kind of rice fertilizer is different during the action period, according to the development of rice seedlings, the second fertilization is carried out against the growing soil, rice needs a lot of water, and the soil in the rice field needs to contain a lot of potassium, Therefore, the fertilizer used for rice planting can also be potassium fertilizer, phosphate fertilizer, etc., and it is not possible to stick to one type. <>

In the process of rice growth, if the nitrogen fertilizer ** is insufficient, it will cause its leaf color to turn yellow, and the yield of the plant is small, resulting in low yield, but nitrogen fertilizer can not be applied too much, which will also cause the leaves of rice to be too long, resulting in lodging, infection with diseases and insects, thereby reducing the yield. What kind of fertilizer is good for rice seedling raising, not only need to look at the rice variety, but also look at the rise of rice in the development and the soil condition of the planting, and combine a variety of factors to carry out appropriate fertilization to ensure the balance of growth. <>

Rice fertilization, need to be carried out in a timely manner after rice transplanting, generally in a week or so, when using fertilizer, to be carried out according to the growth of rice, using too much will affect the growth and development of rice, special attention is that rainy days are not suitable for fertilization, a large amount of rain erosion will reduce the concentration and content of fertilizer, affect the absorption and utilization of fertilizer by rice plants, after fertilization, to keep at least one day is sunny weather, so that fertilizer stays in the soil, convenient for plant roots to absorb.

It is best to choose ternary compound fertilizer. This fertilizer has a lot of nutrients, which is very helpful for the growth of plants and can avoid root rot.

Rice is a common food crop, in the process of rice seedling raising and stooling, try to choose organic fertilizers such as sock travel urea. In this way, we can help rice breed good varieties.

It is better to use synthetic fertilizers or animal manure, which is green and polluting and more helpful to rice.

In my opinion, we should avoid rice "love green", also called "greedy green", and second, to prevent waste, do soil testing formula fertilizer, accurate fertilizer, and improve fertilizer use efficiency. Third, fertilizer should be carried out according to different periods of rice growth and development.

Before the rice is closed, nitrogen fertilizer is the most important, before direct seeding or planting, nitrogen, phosphorus and potassium compound fertilizer should be used as base fertilizer, 15 kg per mu, rice has little demand for organic fertilizer for farmers, and the application of organic fertilizer for farmers is very easy to "secondary fermentation" in rice fields, there is a problem of "burning seedlings" and slow seedlings for a long time, there are too many organic matter, excess nutrition, rice "love green", and lodging problems occur in the middle and late stages. Therefore, generally speaking, 15 kg of nitrogen, phosphorus and potassium compound fertilizer, 5 kg of potassium chloride and 15 kg of superphosphate can be applied per mu of base fertilizer.

7 days after rice planting, the use of manual weeding, nitrogen fertilizer, 5 kg of urea per mu, used as rice tillering, after the gradual tilling of rice, the second nitrogen fertilizer is applied, 10 kg of urea per mu is applied, and the use of manual weeding is carried out. Before the rice is sealed, apply the third nitrogen fertilizer, apply 15 kg of urea per mu, and reduce the drug as appropriate if the rice seedlings are more vigorous.

After the rice is sealed, generally speaking, nitrogen fertilizer will not be applied again, if the rice seedlings grow more vigorously, there is a problem of vigorous growth, it is necessary to "dry the field" as soon as possible, and the rice will stop irrigating for 7 days - 10 days or so, so as to promote the effective tillering of rice, the growth and development of roots, control the vigorous growth of rice, and avoid the lodging of rice "love green". At the booting stage, 5 kg of potassium chloride and 15 kg of superphosphate can be applied to promote rice heading and flowering. At the full heading stage of rice, it is necessary to avoid high temperature and high stuffiness and dampness, and avoid the interference of heat damage on rice pollination, and generally use pumped irrigation to reduce the field temperature.

At the full heading stage and flowering stage of rice, the leaves can be sprayed with potassium dihydrogen phosphate, brassinolides, amino acids, etc., and the leaves can be sprayed with plant growth regulators and trace elements. 300 g of 98% potassium dihydrogen phosphate + 20 g of brassinolide diluted 30 kg leaf spray.

Rice fertilizer, depending on the length of rice seedlings, the seedlings are more vigorous, nitrogen fertilizer can be applied a little less, and the seedling growth is weaker, and a little more nitrogen fertilizer can be applied before the closure. After the closure of the row, apply a little more potassium fertilizer and phosphate fertilizer, and focus on the application of trace elements and plant growth regulators in the middle and later stages.

Rice fertilizer can not be blindly applied, can not be over-applied, to prevent waste, resulting in an increase in production costs, and at the same time overnutrition, resulting in "love green" lodging. In addition, in the rice planting process, pest control is also a top priority, pest control is good, and the amount of chemical fertilizer can also be saved.

Balanced fertilization and fertilization according to the amount, balanced fertilization can supplement the elements, and the amount of fertilization can supplement nutrients in time.

Pay attention to nitrogen fertilizer control. Excessive application of nitrogen fertilizer in rice will cause lodging, aggravation of diseases and pests, resulting in more empty grains and a decrease in seed setting rate, which will affect rice yield. Do not fertilize in rainy days, fertilize cautiously in hot weather and high temperature seasons to prevent fertilizer from accumulating in large quantities in the pond and causing hypoxia in the water body.

Fertilize with caution during turbid water conditions and fish disease outbreaks. Fertilization should not be overdone at one time, especially when dissolved oxygen is low.

I think we should pay attention to the amount of fertilizer applied and the depth of fertilizer. Because if the amount is too much, the seedlings will be burned, and if the amount is too small, the development will not be good. The right depth is conducive to the growth of rice.

1. It is recommended to use nitrogen, phosphorus, and potassium fertilizers to mix and fertilize by yourself. Fertilization should be carried out according to local conditions, and the soil conditions in each region are different, so it is not possible to completely copy the fertilization strategies of other regions.

2. First of all, it is necessary to apply plantar fertilizer, and the combination of organic fertilizer and chemical fertilizer has a better effect. Generally, about 40% of the available nitrogen fertilizer, all the phosphate fertilizer and 60% of the potassium fertilizer are used as base fertilizers. The other 30% of nitrogen fertilizer is used as evil fertilizer.

Finally, the remaining 30% of nitrogen fertilizer and 40% of potassium fertilizer can be used as ear fertilizer.

Generally, rice can be applied basal fertilizer, tillering fertilizer, ear fertilizer and grain fertilizer, it is best to apply organic fertilizer to rice under most conditions and conditions, which can increase the fertility of the soil, and also increase the high yield and stable yield of rice, and the rice needs to apply basal fertilizer before planting, and it is necessary to spray foliar fertilizer to supplement trace elements after half a month of transplanting, nitrogen fertilizer and flower-preserving fertilizer need to be applied at the panicle stage of rice, and a small amount of urea needs to be applied at the grain stage of rice.

Rice fertilizer. Rice is a dust shed and fertilizer-loving plants, from growth to maturity when fertilizer is needed to provide nutrients, generally rice can be applied basal fertilizer, tillering fertilizer, ear pie staring fertilizer and grain fertilizer, in most cases to rice to apply organic fertilizer is the best, can increase the fertility of the soil, but also another rice high yield and stable yield.

Compound fertilizer for rice.

Rice can be used compound fertilizer, the amount of compound fertilizer should be used according to soil fertility to refer to, usually compound fertilizer is used as base fertilizer when rice is just planted, generally rice will have a special compound fertilizer, not only lodging resistance, disease and pest resistance, but also can increase rice yield.

Rice fertilization time.

Rice needs to apply basal fertilizer before planting, need to spray foliar fertilizer to supplement trace elements after half a month of transplanting, need to apply nitrogen fertilizer and flower-preserving fertilizer at the panicle stage of rice, and need to apply a small amount of urea at the grain stage of rice.

Rice fertilization methods and tips.

1. When applying basal fertilizer to rice, the dosage must be sufficient.

2. One week after rice transplanting, it is necessary to apply accelerated organic fertilizer, urea and manure.

3. Potassium fertilizer and nitrogen fertilizer need to be applied to rice at the panicle stage to ensure the yield of rice.

4. Phosphate fertilizer and potassium fertilizer need to be applied after rice grains, which can make the rice grains fuller.

Sprinkle the fertilizer in the water, so that the fertilizer can melt faster and allow the rice to absorb.

When fertilizing, the fertilization method must be selected according to the nutrient demand of the soil and the specific situation of the fertilizer, and the type of fertilization should be selected according to the law of fertilizer demand of crops. In order to make the nutrients in the soil sufficient, the use of basal fertilizer and top dressing should be combined as the principle, and the use of fertilizer can use some organic fertilizer or some inorganic fertilizer for common use. Organic fertilizer is some rotten fermented farm fertilizer produced by farmers for their own use, and these farm fertilizers must be harmless, so as to kill some insect egg pathogens in the soil, as well as the seeds of some weeds, farm fertilizer is the most natural fertilizer.

Rice fertilizer. Rice is a fertilizer-loving plant and needs fertilizers to provide nutrients from growth to maturity. Rice can generally be applied basal fertilizer, tillering fertilizer, ear fertilizer, and grain fertilizer. In most cases, it is best to apply organic fertilizer to rice, which can increase soil fertility and increase high and stable rice yield.

Compound fertilizer for rice.

Rice can be used with compound fertilizer. The dosage of compound fertilizer should be referred to according to soil fertility. Usually when rice is first planted, compound fertilizer is used as a base fertilizer. Generally, rice will have special compound fertilizers, which are not only resistant to lodging, diseases and pests, but also can improve rice yield.

Rice fertilization time.

Rice should be applied basal fertilizer before planting, and foliar fertilizer should be sprayed to supplement trace elements after transplanting for half a month. Nitrogen fertilizer and flower-preserving fertilizer should be applied at the panicle stage, and a small amount of urea should be applied at the rice grain stage.

Rice fertilization methods and tips.

1.When applying basal fertilizer to rice, the amount must be sufficient. 2.

One week after rice transplanting, fast-acting organic fertilizer, urea, and manure should be applied. 3.Potassium fertilizer and nitrogen fertilizer should be applied at the heading stage of rice to ensure rice yield.

4.Phosphate and potassium fertilizers need to be applied after the rice grains come out, which can make the rice grains fuller.
