Temperature control apparatus for watermelon planting

Abstract

The invention discloses a temperature control apparatus for watermelon planting. The temperature control apparatus comprises a greenhouse body which is provided with an air inlet and an air outlet and is also inside provided with a temperature-adjusting channel, a temperature-adjusting mechanism and a temperature-homogenizing mechanism, the air inlet communicates with one end of the temperature-adjusting channel, the other end of the temperature-adjusting channel communicates with the temperature-adjusting mechanism, the other end of the temperature-adjusting mechanism communicates with one end of the temperature-homogenizing mechanism, and the other end of the temperature-homogenizing mechanism communicates with the air outlet. Compared with the prior art, by arranging the temperature-adjusting channel and the temperature-adjusting mechanism, adjustment of the growth temperature of watermelons is facilitated. After the wind enters the temperature-homogenizing mechanism, the wind has relatively small temperature difference variation during flowing in the whole channel and enables the whole greenhouse body to receive the air with a substantially same temperature, thereby preventing plants close to the air inlet and plants close to the air outlet from forming an obvious temperature difference. Temperature adjustment in the greenhouse body is relatively convenient and uniform, so that the watermelons stay in an environment with a proper growth temperature, and thus growth of the watermelons is accelerated.

Description

technical field [0001] The invention relates to the technical field of plant planting buildings, in particular to a watermelon planting temperature control device. Background technique [0002] Since the greenhouse can be suitable for the growth needs of most varieties of watermelon, and has the characteristics of reducing pests and diseases and promoting high yield, more and more watermelons are planted in the greenhouse. The traditional watermelon cultivation technology is to let the watermelon vines grow naturally close to the ground, which has a narrow range of adaptation to humidity and temperature, is vulnerable to pests and diseases, and is not conducive to the development and maturity of watermelons. In addition, watermelon must have a certain intensity of light during the normal growth period. When the sunshine is insufficient, it will make it difficult for the plant to set fruit and cause "melon melting", and the fruit produced will have less photosynthetic product...

AI Technical Summary

Problems solved by technology

[0004] Although the above scheme solves the problems of watermelons not being able to climb and lack of light, there are still the following problems in this scheme: because watermelons like warm and dry climates, are not cold-resistant, and the optimum temperature for growth and development is 24-30 degrees, it is not suitable for watermelon greenhouses. Controlling the temperature in the watermelon can speed up the growth of the watermelon, and the above-mentioned scheme is to adjust the temperature of the watermelon by increasing the height of the watermelon. The temperature accepted by the watermelon is different at different heights, and the operator needs to constantly adjust the height of the watermelon. It is very troublesome, time-consuming and labor-intensive. If it is not adjusted in time, it will affect the growth rate of watermelon
