Frost-damage-preventing light-introduced-decomposition-type planting method for overwintering crops

Abstract

The invention discloses a frost-damage-preventing light-introduced-decomposition-type planting method for overwintering crops and belongs to the technical field of agricultural production. According to the frost-damage-preventing light-introduced-decomposition-type planting method for the overwintering crops, light-introducing heat conducting sticks can be pre-buried at adjacent positions of the overwintering crops to introduce outside light to deep places of soil, photodecomposition coatings on photodecomposition antifrost spheres gradually decompose and liberate oxygen in case of being exposed to light, the oxygen enters multiple sections of internal-arranged heat-release control tubes and then be in contact with a self-heating material so as to trigger heating actions, meanwhile, innercores of fertilizers are assisted to independently disintegrate from outside to inside and provide nutrients for roots of the crops, thus, the light-introducing heat conducting sticks can introduce the light and then trigger heating action and feeding action of the photodecomposition antifrost spheres at a low temperature stage, the soil is heated up, an appropriate growth temperature for the crops is maintained, meanwhile, the nutrients and oxygen essential to growth are provided, the traditional passive defense mode is changed into an active light introducing mode, and the yield of the overwintering crops can be greatly increased while frost damage is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of agricultural production, and more specifically relates to a planting method for overwintering crops to prevent freezing damage and light-induced decomposition. Background technique [0002] Freezing injury is a kind of agricultural meteorological disaster, that is, the low temperature below 0 ℃ makes the body of the crop freeze, causing damage to the crop. Frost damage to overwintering crops, fruit tree freeze damage and economic forest tree freeze damage often occur. Freezing damage is a great threat to agriculture. In my country, it mainly occurs in the northwest, north, east, and south-central regions. The main victims are economic fruit trees such as winter wheat, rapeseed, vegetables, grapes, citrus, camellia oleifera, and tea trees. [0003] China is most affected by freezing damage in the northern part of the northern winter wheat region, mainly in the northern Xinjiang freezing damage area on the...

AI Technical Summary

Problems solved by technology

In the Yangtze River Basin and South China, although the frequency of freezing damage is small, the blocking effect of the hills and mountains on the cold air from the south often makes the cold air accumulate, resulting in a relatively low temperature for a long time, accompanied by snowfall and freezing rain. Beans, rapeseed, broad beans, peas and citrus were severely damaged by freezing

[0004] The current solutions are divided into several types. One is to cultivate cold-resistant varieties, but the investment is high and the cycle is long. The other is to cover the film or other heat preservation measures, but the effect is poor, and the problem of freezing damage cannot be fundamentally solved. The other is Using more fertilization and more watering to assist crops to resist freezing damage, the above methods are too passive and can only reduce the loss of freezing damage, the effect of preventing freezing damage is poor, and the cost is high
