Phosphate fertilizer spraying phosphorus in the late growth stage of rice can increase the seed-setting rate and 1000-grain weight and promote early maturing. Generally, 2% of superphosphate leaching solution is sprayed twice at the heading to filling stage. Preparation method: Take 2 kg of high-quality superphosphate, crush it, pour it into 10 kg of water and soak it for 24 hours (frequently stir), filter it, and spray 60 kg of fertilizer per acre. In the nitrogen-depleted field block, a suitable amount of urea mixed spray can be added to the prepared phosphate fertilizer solution.
Potassium fertilizer sprayed with potassium fertilizer solution once during the booting and heading stages of rice could promote heading and increase seed setting rate. Take 5 kg of fresh grass ash, add 100 kg of fresh water, soak for 12 to 24 hours after mixing thoroughly, and then take the clear liquid spray. Each time about 50 kg of fertilizer solution per acre, 1% potassium chloride solution can also be used.
Zinc fertilizer rice is a sensitive zinc crop. Spraying zinc fertilizer solution once at the heading stage and heading stage can promote the orderly heading, strengthen the blade stamina, accelerate the nutrient operation, and is conducive to irrigation. Each time, 100 grams of zinc sulfate is used per acre, and 50 kg of water is diluted and sprayed. The effect of mixing with potassium dihydrogen phosphate is better and should not be mixed with phosphorus fertilizer.
During the filling stage of rice, boron fertilizer has sufficient supply of boron nutrition, high seed setting rate, and less empty pods, especially in the application of hybrid rice. Generally, 0.1% to 0.2% borax solution is sprayed once at the heading stage and filling stage, which can increase the production by about 10%. For the low-temperature and rainy weather that is not conducive to rice irrigation, it is better to spray boron fertilizer.
Rice leaf surface fertilization effect is good
Nitrogen fertilization after spraying nitrogenous fertilizer at the later stage of rice can extend the functional life and prevent premature denitrification. Generally, 1% urea solution is sprayed once at the booting stage and at the initial stage of grouting.
