High-quality and high-yield planting method for rice

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...

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 extinct, resulting in the decline of soil fertility , crop quality deterioration and other defects

In addition, the application of organic fertilizers on the soil where chemical fertilizers have been applied, due to the lack of decomposition of beneficial microorganisms, the nutrients cannot be released for absorption and utilization by crops, so the fertilizer and absorption rate is low, and the fertilizer efficiency is poor.
