Problems solved by technology

In recent years, with the large-scale popularization of hybrid rice and super rice, problems such as poor tillering, lodging, serious pests and diseases, and yield not reaching the ideal level are often encountered during the cultivation process, and the emergence of these problems also seriously limits High-yield and high-quality production of rice
[0003] When planting rice, rice lodging is a very common problem. This will not only increase the difficulty of rice harvesting, but also cause rice yield reduction. There are various reasons for rice lodging, which has caused great difficulties in the prevention and control work.

Embodiment Construction

[0011] A rice lodging resistance planting method, comprises the following steps:

[0012] (1) Seedling raising: Choose the Longjing 21 rice variety with excellent rice quality and strong lodging resistance. When raising seedlings, pay attention to the application of potassium fertilizer. In the entire seedling raising period, the ratio of nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer is 2:1:2;

[0013] (2) Growth period: When fertilizing during the growth period, strictly control the amount of nitrogen fertilizer applied. The amount of nitrogen fertilizer applied per mu during the entire growth period is 40-50kg. Spray foliar fertilizer once at the tillering and jointing stages. The foliar fertilizer formula is potassium sulfate, sulfuric acid Zinc and ammonium molybdate, the ratio is 15:3:1, dosage per mu: mix 5kg of potassium sulfate, zinc sulfate and ammonium molybdate in proportion to 60L of tax water and spray it in the paddy field; spray at tillerin...

Abstract

The invention discloses an anti-lodging rice planting method. A good anti-lodging rice variety is selected, and scientific fertilization and chemical stuntedness are combined, so that overhigh stems of rice are avoided during the growth of rice, and the purpose of lodging resistance is reached. Through practice observation of many years, the probability of occurrence of lodging is less than 1%.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a rice lodging-resistant planting method. Background technique [0002] As one of the main food crops in my country, rice has the characteristics of wide planting area and large area, which is of great significance to my country's food security, so rice production has always been a hot field of research. In recent years, with the large-scale popularization of hybrid rice and super rice, problems such as poor tillering, lodging, serious pests and diseases, and yield not reaching the ideal level are often encountered during the cultivation process, and the emergence of these problems also seriously limits High-yield and high-quality rice production. [0003] When planting rice, rice lodging is a very common problem. This will not only increase the difficulty of rice harvesting, but also cause rice yield reduction. There are various reasons for rice lodging, which has caused great diff...
