Description

Rice planting method

Technical Field

The invention relates to the field of rice planting.

Background

With the improvement of the living standard of people, the basic solution of the problem of satiety and the gradual realization of the goal of well-being, the health consumption demand of people is increasing day by day, the quality safety of agricultural products becomes a global concern, the safety and the physical health of people are directly related, and the market competition of the agricultural products is also influenced. Therefore, the method protects resources and environment, establishes a production system for saving resources, strengthens agricultural pollution-free standardized production, is an important way for continuously improving the level of agricultural industry and enhancing market competitiveness, is also an important way for enhancing the physical health of urban and rural people, realizing economic, ecological and social benefits and promoting the sustainable development of national economy and society. Therefore, the research on the planting method of high-yield and high-quality rice is the key point of the future work of rice researchers.

disclosure of Invention

the invention aims to provide a rice planting method, which has the advantages of high reliability, environmental protection, high yield and the like, and has wide market prospect in the application and popularization of rice planting.

In order to achieve the purpose, the invention adopts the following technical scheme:

A method for planting rice comprises the following steps:

(1) Seed treatment: selecting rice seeds which have no plant diseases and insect pests and are strong and have plump seeds, soaking the rice seeds in a sodium peroxide aqueous solution for 30-40min, soaking the seeds in a carbendazim wettable powder solution of 400-fold and 450-fold for 18-22 h, cleaning and airing.

(2) Sowing and raising seedlings: adopting a seedling raising tray to raise seedlings, mixing plant ash, peat, fine sand and humus according to a mixing ratio of 8-10:4-6:6-7:10-15, fully and uniformly stirring, adjusting the humidity of culture soil to be 50% -60%, uniformly paving the culture soil in the seedling raising tray, slightly pressing seeds into the culture soil, sowing 2 seeds in each seedling raising tray according to the standard that the seeds are just covered by sludge, covering a layer of film on the surface of the seedling raising tray after sowing is finished, lifting the film after the rice seedlings sprout, ensuring that the rice seedlings are irradiated with light for 4-5 hours every day, controlling the temperature at 25-30 ℃ in the daytime and controlling the temperature at 20-22 ℃ at night; replenishing water in a proper time during the growth period of rice seedlings, keeping the water content in a seedling raising plate to be 45-50%, and simultaneously performing additional fertilization once, wherein the additional fertilization is performed by spraying 0.08-0.12% of urea and 0.15-0.22% of monopotassium phosphate solution after rooting; when the seedlings grow to 5-6cm, transplanting the seedlings together with the soil matrix.

(3) Transplanting and inserting seeds and putting fields: 1 month before transplanting, applying 1200kg of base fertilizer to each mu of a planting field, deeply ploughing for 25-30cm, transplanting with a seedling culture medium during transplanting, planting rice in wide and narrow rows with the row spacing of 12cm multiplied by 50cm, and watering after transplanting; after transplanting and planting for 16-18 days, starting to put the field when the number of seedlings per mu reaches 15-16 ten thousand, and lasting for 5-7 days.

(4) Field management: applying 25kg of urea and 10kg of potassium chloride per mu 7-10 days after transplanting; after 10-12 days, applying 10kg of compound fertilizer as balance fertilizer per mu; when 4 leaves are poured and the tips are exposed, 10-15kg of urea and 5kg of compound fertilizer are applied to each mu of land as the flower promoting fertilizer; when 2 leaves are poured and the tips are exposed, applying 10kg of compound fertilizer per mu to serve as flower protection fertilizer; the annual pure nitrogen fertilizing amount is 30-32 kg.

(5) irrigation and drainage: the shallow water layer is still kept in the field in the early stage of irrigation, the physiological water demand of the rice is reduced after the rice is ripened by wax, the requirement can be met when the soil moisture is wet, and the water is cut off in the field one week before harvest.

(6) Harvesting: when the rice ears hang down and are golden and full, the rice can be harvested.

The invention has the beneficial effects that: the invention can not only improve the yield of the rice, but also improve the safety and the taste of the rice without using pesticides and medicines, and simultaneously improve the nutritional value of the rice.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below.

Example 1

(1) Seed treatment: selecting strong and plump rice seeds without plant diseases and insect pests, soaking in sodium peroxide water solution for 30-40min, soaking in 400 times of carbendazim wettable powder for 20 hr, cleaning, and air drying.

(2) Sowing and raising seedlings: adopting a seedling raising tray to raise seedlings, mixing plant ash, peat, fine sand and humus according to a mixing ratio of 8:6:6:12, fully and uniformly stirring, adjusting the humidity of culture soil to be 50% -60%, then uniformly paving the culture soil in the seedling raising tray, slightly pressing seeds into the culture soil, seeding 2 seeds in each seedling raising tray according to the standard that the seeds are just covered by sludge, covering a layer of film on the surface of the seedling raising tray after seeding is completed, lifting the film after the rice is raised and germinated, ensuring that the rice seedlings are irradiated for 4-5 hours every day, controlling the temperature at 25-30 ℃ in the daytime and controlling the temperature at 20-22 ℃ at night; replenishing water in a proper time during the growth period of rice seedlings, keeping the water content in a seedling raising plate to be 45-50%, and simultaneously performing additional fertilization once, wherein the additional fertilization is performed by spraying 0.08-0.12% of urea and 0.15-0.22% of monopotassium phosphate solution after rooting; when the seedlings grow to 5-6cm, transplanting the seedlings together with the soil matrix.
