Greenhouse body structure for fruit tree rainproof cultivation

Abstract

The invention discloses a greenhouse body structure for fruit tree rainproof cultivation. The greenhouse body structure is structurally composed of multiple greenhouse body units, each greenhouse bodyunit is arranged independently, and a gap is formed between every two greenhouse bodies; on one hand, in natural rainfall, rainwater falls into spaces between lines of fruit trees, so that natural rainfall is effectively utilized, on the other hand, the size of the whole greenhouse body structure can be adjusted according to an actual planting area, and in other words, the number of the greenhouse body units and the length of each greenhouse body unit are adjusted; the greenhouse body structure is designed into an integral through transverse rods in an orchard and is an open structure, in this way, the anti-wind capacity of a greenhouse is enhanced, and the greenhouse body structure is firm and durable.

Description

【Technical field】 [0001] The invention belongs to the technical field of agricultural facility cultivation, and relates to a shed structure for rainproof cultivation of fruit trees. 【Background technique】 [0002] Jujubes, grapes, apples and other fruit trees are extremely vulnerable to rain damage during production and produce cracked fruit. For example, in northern Shaanxi jujube areas, the loss of cracked fruit in a normal year is 30-70%, and grapes in rainy years, cracked and rotten fruit is also more than 30%. Regarding jujube fruit cracking, domestic scholars have conducted a lot of research in terms of mechanism and control countermeasures. At present, they mainly use comprehensive agricultural technology methods for prevention and control, such as balanced fertilization, chemical control, early harvesting, etc., but these methods can reduce fruit cracking. It has a certain control effect, but it cannot fundamentally solve the problem of fruit cracking. For example, i...

Regarding jujube fruit cracking, domestic scholars have conducted a lot of research in terms of mechanism and control countermeasures. At present, they mainly use comprehensive agricultural technology methods for prevention and control, such as balanced fertilization, chemical control, early harvesting, etc., but these methods can reduce fruit cracking. It has a certain control effect, but it cannot fundamentally solve the fruit cracking problem. For example, in the cultivation and production of jujube, the fruit cracking rate of jujube can be reduced by about 10% by adding organic fertilizer or bacterial fertilizer

In recent years, facility rainproof technology has been widely used in production, such as bamboo and wood structure rainproof sheds and steel frame structure rainproof sheds. rice, covering 3-5 rows of fruit trees, they have three major disadvantages, one is that the rainwater cannot enter the orchard after covering, so that the natural precipitation cannot be fully utilized; The air is used to reduce the temperature inside the shed, which increases the cost of labor input; the third is that the shed is huge, if there is no air outlet, it is easy to cause the shed to collapse in windy weather
