Double-heat-source semi-automatic cultivation facilitating system for large cherries

Abstract

The invention belongs to the technical field of off-season cultivation for large cherries, and relates to a double-heat-source semi-automatic cultivation facilitating system for large cherries. The system comprises a ridge-shaped plastic house, a double-heat-source heating unit and an axial flow fan. Compared with the traditional plastic houses and greenhouses for cultivating the large cherries, the double-heat-source semi-automatic cultivation facilitating system has the advantages that a ground heatable brick bed type supplementary heating mode is adopted, the dimensions (including the roof height of 7.5m and a slope factor of 3 / 10) of a house body are reasonably set, the cultivation environment control volume is increased, internal environmental factors of the house are jointly controlled in a semi-automatic manner, and the temperature of the house is adjusted in a balanced manner, so that a cultivation environment is stable relatively, the quality of the appearance of the fruits is generally improved, the sizes of the fruits are uniform, colors of the large cherries are bright, fruit cracking and freezing injury are prevented, the average yield per mu is higher than 600kg, the average excellent cherry rate is higher than 90%, shortcomings of unstable quality and yield of cherries cultivated in the traditional cultivation plastic houses and greenhouses are overcome, and the economical benefit of the double-heat-source semi-automatic cultivation facilitating system is increased by nearly 10 times as compared with an open-field cultivation mode.

Description

technical field [0001] The invention relates to a semi-automatic cultivation system for large cherries with dual heat sources, and belongs to the technical field of off-season cultivation of large cherries. Background technique [0002] Big cherry (also known as sweet cherry) is a fruit tree species introduced from Europe. After 1995, it developed rapidly in my country. Because of its beautiful appearance, rich nutrition, sweet and delicious taste, it matures earlier than other fruits in a year, so its economic benefits are particularly high. Since 2007, the large cherries cultivated in the open field with full fruit tree age, every 666.7 m 2 The average annual net income is higher than 11,500 yuan; and the use of suitable facilities to promote cultivation can increase the annual net income. After 2000, the domestic cultivation area of ​​large cherry facilities increased rapidly, and various large cherry cultivation greenhouses and greenhouses appeared in various places. ...

AI Technical Summary

Problems solved by technology

It is mainly manifested in four aspects. One is that the natural dormancy cooling capacity of large cherry trees is completely recorded manually, and the human error is large, which leads to inaccurate heating time of the shed. economic benefits)

The second is that the traditional mercury column, kerosene column and mechanical induction detection instruments are generally used in the detection of environmental factors. These instruments are cheap, but have slow response speed and single function. The operating error is very large, especially at night or in rainy and snowy weather, it is difficult to timely and accurately control the environmental factors in the shed

The third is that the structure of the shed is unreasonable, and the slope between the shoulder height and the top height is unscientific, which makes the shed body weak against wind and snow, and there are potential safety hazards

The fourth is to only use solar energy as a single heat source for heating. When encountering continuous cold weather or extremely low temperature, the temperature of the shed exceeds the lower limit requirement, resulting in a serious decline in output and quality.

In production practice, it is found that when the existing heating device is used to heat the shed, the cost is high, the local temperature rises and cools too fast, and the temperature in the shed is not balanced, resulting in inaccurate monitoring results, which ultimately leads to a decrease in fruit yield and quality
