Disease-resistant and lodging-resistant rice-dressing nutritional fertilizer

Abstract

The invention discloses a disease-resistant and lodging-resistant rice-dressing nutritional fertilizer. The disease-resistant and lodging-resistant rice-dressing nutritional fertilizer is prepared from, by weight, 35-37 parts of urea, 12-14 parts of potassium sulfate, 11-13 parts of ammonium nitrate, 7-9 parts of copper sulfate, 16-18 parts of diammonium phosphate, 2.6-2.8 parts of sodium gluconate, 11-13 parts of corn straws, 6-8 parts of soybean hulls, 0.7-0.9 part of cellulase, 5-7 parts of coconut shell activated carbon and 2.1-2.3 parts of traditional Chinese medicine additive. The raw materials for the nutritional fertilizer include the traditional Chinese medicine additive, are scientific in compatibility and complement each other in effect, and the nutritional fertilizer can not only make rice roots and stems strong and not easily lodge and can also effectively improve disease resistance and reduce the disease rate. The coconut shell activated carbon is added in the fertilizer so that the traditional Chinese medicine additive and other nutrients can immerse pores of the coconut shell activated carbon to achieve slow release, nutrient absorption and utilization of rice can be not only promoted and the fertilizer efficiency of the fertilizer can be prolonged, the disease resistance and lodging resistance of the nutritional fertilizer are enhanced, and thus the yield of the rice is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a disease-resistant and lodging-resistant topdressing nutrient fertilizer for rice. Background technique [0002] Paddy rice originates in Tropical Asia, is annual gramineous plant, 24 chromosomes, and the rice grain of end is called rice or rice after shelling. Nearly half of the world's population feeds on rice. There are various ways to eat rice, such as rice, rice porridge, rice cakes, rice cakes, rice noodles, rice wine and so on. In addition to being edible, rice can also be used for starch production, wine making, and vinegar production. Rice bran can be used for sugar production, oil extraction, and furfural extraction for industrial and medical purposes. Rice husk and rice straw also have many uses. [0003] In the process of rice planting, due to the use of unreasonable fertilizers, not only the absorption rate of rice to fertilizers is low, but also lead to slow ...

AI Technical Summary

Problems solved by technology

[0003] In the process of rice planting, due to the use of unreasonable fertilizers, not only the absorption rate of rice to fertilizers is low, but also lead to slow growth, poor disease resistance, and easy lodging, which leads to a decline in yield and reduces the economy of growers. In addition, the fertilizers used by some growers contain harmful ingredients that are difficult to degrade, which may cause certain harm to the human body when eaten, and cause certain panic to people
