Planting method for preventing cold damage of rice

Abstract

The invention discloses a planting method for preventing cold damage of rice. The planting method for preventing cold damage of rice comprises the following steps: 1, sowing seeds in good time to avoid cold damage; 2, selecting an anti-cold variety; 3, carrying out dry nursery and sparse seeding to cultivate strong seedlings; 4, applying fertilizers reasonably to ensure premature; 5, regulating temperature by using water to relieve cold damage; and 6, spraying with a self-made leaf fertilizer in a whole process to accelerate rapid filling and prematurity. The rice cultivated by the method canbe protected from being affected by low temperature, the yield of the rice is greatly higher than the yield of rice cultivated conventionally, and the economic benefit and the social benefit are obvious.

Description

technical field [0001] The invention belongs to the technical field of rice planting methods, and in particular relates to a planting method for preventing low-temperature chilling damage of rice. Background technique [0002] Chilling injury is one of the common meteorological disasters in rice production in my country. Due to the impact of low temperature and chilling damage, it often causes heavy losses to rice production. After the seedling stage is damaged by low temperature, the leaves of the whole plant turn yellow, the lower part of the plant produces yellow leaves, some leaves appear brown, and some leaves appear white or yellow to yellow-white horizontal stripes, commonly known as "section yellow" or "section white". ". In the 2-3 leaf seedling stage, if the daily average temperature continues to be lower than 12°C, rotten seedlings are prone to occur. After chilling injury at the booting stage, the number of spikelets was reduced and the development of young pa...
