Ammonium polyphosphate rice foliage fertilizer and preparation method thereof

Abstract

The invention relates to ammonium polyphosphate rice foliage fertilizer and a preparation method thereof. The ammonium polyphosphate rice foliage fertilizer is prepared from the following raw materials in parts by weight: 13-15 parts of ammonium polyphosphate, 24-27 parts of urea, 18-20 parts of potassium chloride, 1-2 parts of biochemical potassium fulvate, 0.04-0.06 part of magnesium nitrate, 0.03-0.05 part of calcium nitrate, 0.3-0.5 part of trace elements, 0.05-0.1 part of brown sugar, 20-30 parts of a bactericidal insect repellent agent, 0.1-0.15 part of tea saponin and 150-200 parts of water. The ammonium polyphosphate rice foliage fertilizer prepared by the method is rich and balanced in nutrition and rich in various nutrients as well as medium and trace elements, and can rapidly supplement the nutrients needed by rice; the fertilizer efficiency of the rice foliage fertilizer is good and lasting. After being sprayed onto the rice, the foliage fertilizer can promote rice seedlings to grow strongly, realizes effective tillering, enables the stems to be thick and strong, and can improve the diseases resistance, insect damage resistance and lodging tolerance of the rice; furthermore, after the foliage fertilizer is sprayed onto the rice at the later stage of growth, the pollination rate and ripening rate of the rice can be improved, empty grains and abortive grains are reduced, the seed kernel weight and the thousand seed weight are increased, and the quality of the rice is improved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an ammonium polyphosphate rice leaf fertilizer and a preparation method thereof, belonging to the technical field of fertilizer production. Background technique [0002] Rice is an annual grass plant with long and flat leaves and panicles composed of many spikelets. It is an important food resource. People in many parts of the world rely on it as a staple food. Especially in my country, rice is the mainstay of my country's agriculture. The main crops play an important role in the adjustment of my country's agricultural structure and food security. The sown area of ​​rice in my country accounts for about 29 percent of all food crops, and about 60 percent of the population uses it as a staple food. However, at present, my country's population is growing rapidly and the area of ​​cultivated land continues to decrease. This also puts great pressure on the cultivation and supply of rice. We must cultiv...

AI Technical Summary

Problems solved by technology

However, in the current foliar fertilizer varieties, most of the foliar fertilizers have problems such as single fertilizer effect, narrow application range, difficult storage and transportation, poor stability, and high cost.

Moreover, the effect of foliar fertilizer with single fertilizer effect on rice is not ideal, it cannot meet the growth needs of rice, and the production cost of fertilizer is relatively high, which lacks economy.

Moreover, most of the trace elements supplemented in the foliar fertilizer of rice are added to the fertilizer in the form of inorganic salts, and its utilization rate is easily affected by the phosphate added together, which reduces the absorption efficiency of rice to trace elements and also Affects the uptake efficiency of phosphorus in rice
