Good-quality and high-yield planting method for rice

Abstract

The invention discloses a good-quality and high-yield planting method for rice. The planting method is characterized in that a nutrient is applied in a growth period of the rice, wherein the nutrient mainly comprises the following components by weight percent: 10-80% of nucleotide potassium salts and deoxynucleotide potassium salts and 20-90% of sugar and / or amino acid; 10-30g of the nutrient is added with 10-54l of water and is applied in each mu (unit of area) of farmland in a spraying manner; and the timings for applying the nutrient are that the nutrient is sprayed twice in the growth period of the rice, specifically the nutrient is sprayed for the first time when the head of the rice sprouts by 10% and is sprayed for the second time after 5-6 days of the first spraying. The good-quality and high-yield planting method has the advantages that the nutrient has no toxicity, harm, residue and any adverse side effect to the rice; the nutrient is beneficial to increasing of the yield and the income and improving the efficiency and has good effects of enhancing the resistance and improving the quality for plants; and the method has a simple process, the cost is low and large-scale production and promotion are easy.

Description

[0001] This application is a divisional application with application number 201010514217.6, application date: October 21, 2010, and the title of the invention is "a nutrient for promoting plant growth and its preparation method". technical field [0002] The invention relates to a planting method of food crops, in particular to a high-quality and high-yield planting method of rice. Background technique [0003] Vigorously developing planting and forestry, increasing crop production and income, and greening the motherland are issues that scientists from all over the world are concerned about. The growth of plants is inseparable from supplementary nutrition. The current planting industry mainly relies on the application of nitrogen, phosphorus, potassium fertilizers and organic fertilizers. To promote the growth of crops, excessive application of fertilizers has a great impact on the quality and flavor of crops, which is not conducive to the development of green agriculture, fo...

Problems solved by technology

[0004] There are nucleosides, nucleotides, purines, pyrimidines and other small nucleic acid molecules and a small amount of reducing sugars and very few large, medium and trace elements. Ribonucleic acid is used as raw material and enzymatically hydrolyzed, which has high production costs, incomplete degradation, very little deoxynucleotide content, low yield of nucleotide salts in the mixed system, various nucleotide salts and deoxynucleotide salts Mutual matching ratio is out of balance, which has a great influence on the use effect

Chinese patent document (publication number: 101050143) discloses a nutrient that promotes the growth of crops, which is composed of ribavirin and glucose. The production of ribavirin is closely related to guanosine. The cost of ribavirin in this patent is too high , the problem that the actual use effect is not obvious; Chinese patent literature (publication number: 1238323) discloses a preparation method of nucleic acid foliar fertilizer, the degradation of its nucleic acid adopts the method of alkaline hydrolysis, and the degradation products are purine and pyrimidine. There are also problems that the cost of nucleic acid is too high, and the ratio of various nucleotide salts and deoxynucleotide salts is unreasonable, which affects the use effect.
