Problems solved by technology

Long-term application of simple fertilizers will have adverse effects on soil and crops
In the prior art, the development from farmyard manure to chemical fertilizer, the application of chemical fertilizer has led to a rapid development of agricultural production, but chemical fertilizer pollutes the environment, compacts the soil, destroys the soil structure, and makes many beneficial organisms in the soil gradually extin

Embodiment Construction

[0019] The present invention will be further described below through specific embodiments, but they should not be construed as limiting the protection scope of the present invention.

[0020] A high-quality and high-yield planting method of rice, comprising the following steps:

[0021] (1) Soil preparation: Before planting rice, the soil of the paddy field must be turned over to make it soft, the depth of the plow layer should be 20-25 cm, and the base fertilizer should be applied;

[0022] (2) Seed treatment: use a sodium chloride solution with a mass ratio of 12% to float and select seeds, pull out the plump rice seeds that have settled, wash them with clear water, put the seeds into 1000 times of carbendazim solution and soak for 72 hours, every 6 hours Stir once to make the upper and lower seeds evenly covered with medicine. After the disinfection is completed, remove the seeds, then treat the seeds with hydrogen peroxide for half an hour, then rinse them with clean water...

Abstract

The invention discloses a high-quality and high-yield planting method for rice. The method comprises the steps of: soil preparation, seed treatment, seedling, transplanting, fertilizing management and the like. According to the method disclosed by the invention, the fertilization time of rice is reasonably arranged, so that sufficient fertilizer supply is available in an earlier stage, a middle stage and a later stage. Meanwhile, special fertilizers for two stages respectively after rice seedling and rice transplanting are blended, the utilization ratio of the fertilizers by rice is improved for the demand of rice on nutrition in different growth periods, and nutritional value, and cold-resisting, disease-resisting, drought-resisting and flood-resisting properties of the rice are enhanced.

Description

technical field [0001] The invention relates to crop planting technology, in particular to a rice planting technology. Background technique [0002] Rice is one of the main food crops, and it is also a high-yielding crop. The sown area of ​​rice in my country accounts for about 1 / 4 of the total area of ​​grain crops, and the output is close to 1 / 2 of the total grain output of the country. Therefore, rice plays an important role in my country's grain production. [0003] High-yield and high-quality rice varieties with a yield of 550 kg, 650 kg, and 700 kg per mu have been continuously introduced, but when they are promoted on a large scale, the average yield per unit is only 450 kg. The main reason is that the current fertilization technology of "heavy front, hollow, and late supplement" is used in rice cultivation, coupled with the transplanting of dense seedlings, which leads to the imbalance of rice growth, fertilizer, water and air, the ups and downs of seedlings, and th...
