Description
Technical Field
the invention relates to the technical field of rice planting, in particular to a rice planting method.
Background
the rice is the main grain crop in China, the sowing area of the rice in China is about 1/4 of the total area of the grain crop, and the rice yield is 1/2 of the total grain yield. Therefore, rice production plays a significant role in grain crop production. Rice has high nutritive value, and the rice bran as the by-product after processing contains about 14% of protein, about 15% of fat, about 2% of phosphide and a considerable amount of vitamins, is a concentrated feed for livestock and poultry, and is closely related to the supply of meat, eggs and milk of people in cities and countryside. Therefore, the development of rice production and the increase of rice yield have very important significance for improving the life of people and promoting the development of national economy.
the rice planting is generally divided into a seeding stage, a seedling stage, a tillering stage, a spike growing stage and a maturing stage, wherein the steps of pre-treatment including airing, seed selection, disinfection and germination acceleration are needed before seeding, and because the pre-treatment process has randomness and the yield of the existing rice planting method is low, the yield is improved from rice varieties to a certain effect, but the yield cannot be improved from the rice planting method to achieve an ideal effect.
disclosure of Invention
the invention aims to provide a rice planting method with strong disease resistance, high yield and early breeding.
A method for planting rice comprises the following steps:

Because the temperature in the soil is lower, the soil is ploughed and aired, the temperature in the soil can be improved, the growth of crops is facilitated, and the root cause of plant diseases and insect pests can be reduced from the soil layer.
Further, in the step (1), the fertilizer is prepared from the following raw materials in parts by weight: 5-8 parts of eggshells, 20-30 parts of fermented organic fertilizer, 1-3 parts of EM (effective microorganisms), 10-15 parts of urea, 3-5 parts of ferrous sulfate and 3-5 parts of manganese sulfate.
the fertilizer adopted by the invention can provide rich nutrient components for seedlings, improve soil, improve the air permeability of the soil, reduce the growth resistance of roots and stems, increase beneficial microbial populations in the soil, inhibit the growth of pathogenic bacteria, promote the photosynthesis of crops and accelerate the growth of root crops.
preferably, in the step (1), the fertilizer consists of the following raw materials in parts by weight: 6 parts of eggshells, 25 parts of fermented organic fertilizer, 2 parts of EM (effective microorganisms) bacteria, 12 parts of urea, 4 parts of ferrous sulfate and 4 parts of manganese sulfate.
Further, in the step (2), the disinfectant is a plant ash aqueous solution, and the weight ratio of the plant ash to the water is 6-8: 100.
Preferably, the rice seeds are soaked in the disinfectant for 2-3 days, and the weight ratio of the soaked rice seeds to the wood ash in the disinfectant is 1: 1-2.
the plant ash has strong effect of killing pathogenic bacteria and viruses, has the effect similar to that of common strong disinfectant caustic soda, has good effect of preventing and treating rice blast, bakanae disease and bacterial leaf blight, and can ensure that seeds germinate fast, emerge uniformly and grow robustly.
Further, in the step (2), the disinfected rice seeds are put into warm water with the temperature of 35-38 ℃ for soaking for 25-35 min.
Further, in the step (3), the nutrient soil is prepared from the following raw materials in parts by weight: 100-300 parts of sand soil, 20-30 parts of livestock manure, 50-80 parts of bean cake powder, 10-30 parts of urea and 3-8 parts of EM (effective microorganisms) bacteria.
further, in the step (3), the nutrient soil is prepared from the following raw materials in parts by weight: 200 parts of sandy soil, 25 parts of livestock manure, 65 parts of bean cake powder, 20 parts of urea and 5 parts of EM (effective microorganisms).
Further, in the step (3), the temperature of the greenhouse culture is 28-30 ℃, and the humidity is 55-60%.
The invention has the beneficial effects that: the rice field is treated before rice transplanting, so that the incidence rate of diseases and insect pests of rice seedlings is reduced, and rich nutritional ingredients are provided for the growth of the rice seedlings; the method has the advantages that the rice seeds are soaked in the plant ash aqueous solution in the rice seed treatment process, pathogenic bacteria and viruses are killed from the root source, in the seedling raising process, the adopted nutrient soil can enable the root systems of the rice seedlings to be robust and developed, the nutrient absorption is faster, the rice seedlings do not damage the roots in the transplanting process, the seedling revival is not needed, the survival rate of the rice seedlings can be improved, and the yield of the rice is further improved.
the rice planting method provided by the invention improves the survival rate of seedlings, radically reduces the occurrence of plant diseases and insect pests, does not need to revive the seedlings in the transplanting process, and can absorb rich nutrient components from soil, so that the rice has the characteristics of early breeding and high yield.
