Problems solved by technology

Therefore, utilize the common fertilizer formula on the market, according to the common compound fertilizer formula on the market (the ratio of the nitrogen, phosphorus and potassium content of the general compound fertilizer is respectively calculated with the ratio of the mass percentage composition of nitrogen element, phosphorus pentoxide and potassium oxide as 15:15:15 or 16:16:16) not only causes a lot of waste of fertilizer, but also easily causes the lodging of water-saving and drought-resistant rice
Lodging will greatly increase farmers' harvesting costs and affect the commodity value of rice, which may lead to failure to harvest in severe cases

Embodiment 1

[0030] A special compound fertilizer for water-saving and drought-resistant rice, characterized in that the compound fertilizer includes main fertilizer and auxiliary fertilizer, and the main fertilizer includes 6.47kg slow-release urea, 10kg ammonium dihydrogen phosphate, 19.6kg potassium chloride and 37.2kg chlorine Ammonium chloride, the auxiliary fertilizer includes 3kg zinc sulfate monohydrate, 5kg humic acid and 2kg water-retaining agent carboxymethyl cellulose, and the nitrogen, phosphorus and potassium content ratio in the main fertilizer is represented by nitrogen element, phosphorus pentoxide and potassium oxide respectively The ratio of the mass percent content of the calculation is 18:6:16. Wherein the nitrogen content in the urea is 46%, the nitrogen content in the slow-release urea is 44%, the nitrogen content in the monoammonium or ammonium dihydrogen phosphate is 11% and the phosphorus pentoxide content is 44%, and the nitrogen content in the potash fertilizer i...

Embodiment 2

[0032] A special compound fertilizer for water-saving and drought-resistant rice, characterized in that the compound fertilizer includes main fertilizer and auxiliary fertilizer, and the main fertilizer includes 5.51kg urea, 10kg ammonium dihydrogen phosphate, 19.6kg potassium chloride and 38.4kg ammonium chloride , the auxiliary fertilizer includes 4kg zinc sulfate heptahydrate, 7kg humic acid and 3kg water-retaining agent carboxymethyl cellulose, and the nitrogen, phosphorus and potassium content ratio in the main fertilizer is based on the quality of nitrogen element, phosphorus pentoxide and potassium oxide respectively The ratio of percentage content is calculated as 18:6:16. Wherein the nitrogen content in the urea is 46%, the nitrogen content in the slow-release urea is 44%, the nitrogen content in the monoammonium or ammonium dihydrogen phosphate is 11% and the phosphorus pentoxide content is 44%, and the nitrogen content in the potash fertilizer is 60%, and the nitrog...

Abstract

The invention provides a special compound fertilizer for water-saving and drought-resistant rice.The compound fertilizer comprises a main fertilizer and an auxiliary fertilizer, wherein the main fertilizer comprises urea and / or slow-release urea, ammonium dihydrogen phosphate, potassium chloride and ammonium chloride; the auxiliary fertilizer comprises a zinc fertilizer, humic acid and a water retaining agent; and the ratio of nitrogen to phosphorus to potassium in the main fertilizer is (16-20):(5-8):(14-18) based on the mass percentage of nitrogen, phosphorus pentoxide and potassium oxide. Acertain amount of zinc fertilizer is added correspondingly while the content of the phosphate fertilizer in the main fertilizer of the composite fertilizer is reduced. The means of 'phosphorus reduction and zinc addition' effectively reduces the zinc-phosphorus antagonism in the compound fertilizer, so that the zinc fertilizer in the water-saving and drought-resistant rice can be fully absorbed.The plants are tall, robust and strong in stress tolerance, and the grains are thick and full. Therefore, the compound fertilizer is beneficial to improvements on the quality and yield per mu of the water-saving and drought-resistant rice.

Description

technical field [0001] The invention relates to the field of rice compound fertilizer, and in particular to a special compound fertilizer for water-saving and drought-resistant rice. Background technique [0002] "Water-saving and Drought Tolerance Rice (WDR)" is a new type of cultivated rice. In 2015, the Ministry of Agriculture officially promulgated the "Terms of Water-saving and Drought-resistant Rice" and "Drought Resistance Identification Technology of Water-saving and Drought-resistant Rice". Specifications, two industry standards define the term. [0003] The water-saving and drought-resistant rice has both the high-quality and high-yield rice and the water-saving and stress-resistant characteristics of upland rice. And it specifically includes three basic features: First, it is planted in high-yield fields with better irrigation conditions. The yield and rice quality are the same as ordinary rice, but it can save 50% of water and greatly reduce the use of pesticide...
