Method for preventing and controlling flower freezing and fruit freezing of armeniaca sibirica due to late frost by Chinese pine big umbrella forest

Abstract

The invention provides a method for preventing and controlling flower freezing and fruit freezing of armeniaca sibirica due to late frost by a Chinese pine big umbrella forest. According to the method, Chinese pines are planted on the periphery of an armeniaca sibirica forest and in vacant spaces inside the forest; the height of the Chinese pines is more than 50cm higher than the height of the armeniaca sibirica; the planting row spacing of the Chinese pines is (5 to 6)*(6 to 8); the plant number ratio of the armeniaca sibirica to the Chinese pines is (6 to 8):1; and before the Chinese pines are planted, the planting density of the armeniaca sibirica is controlled to be 110 plants / mu. The method provided by the invention is used for a large-area armeniaca sibirica forest with possibility of suffering from late frost disasters; an umbrella-shaped protection forest formed by planting the Chinese pines can effectively decelerate the wind speed to achieve the effects of a plurality of small wind barriers, and can be used for effectively weakening cold air in winter, shading the burning sun in summer and shielding late frost and early frost in spring and autumn; the site conditions canbe improved; the seedling preserving rate, the fruiting rate and the yield can be improved; the natural environment can also be beautified; no any pollution and no safety hazard can be generated; andthe method conforms to an ecological civilization development mode.

Description

technical field [0001] The invention relates to a method for preventing and controlling late frost, flower and frozen fruit disasters of mountain apricot, in particular to a method for preventing and controlling late frost, flower and fruit of mountain apricot by using large umbrella forests of Chinese pine. Background technique [0002] Prunus apricot can not only beautify the green environment, but also increase farmers' income. It is a pioneer tree species and an economic tree species for afforestation in the semi-arid areas of northern my country. During the flowering period, apricots often encounter late frost hazards, which seriously affect the growth and fruiting of apricots, resulting in reduced production or even no harvest. The harm of apricot late frost is a worldwide problem. Researchers at home and abroad have carried out a large number of experimental studies and developed a variety of anti-frost methods and technologies with different ideas, but each of these ...

AI Technical Summary

Problems solved by technology

The adaptation of cold-resistant apricot flat varieties is mainly aimed at places with fertile soil, gentle slopes, and good site conditions. It cannot be used in places where the site conditions are poor and cannot meet the needs of cultivating varieties.

Technical measures such as spraying antifreeze, spraying water, root irrigation with antifreeze, watering, and whitewashing require water source conditions, but also consume a lot of labor and material energy. The input cost is too high, and it is difficult to achieve large-scale application

The blower needs a power source, and the smoke is easy to cause certain pollution and fire
