Because the temperature in the shed is still high during the daytime, many vegetable farmers are still using hormones to control the length of the squash, resulting in slow growth of squash, and some even appear hormonal poisoning. Because it has entered the winter season, the temperature difference between day and night in the shed is relatively large. The vegetable grower can completely control the temperature and use non-pollution cationic active agents without hormones.
Grass drapes have been installed on the current sheds. After the straw drapes were all put down at night, the minimum temperature in the sheds was 16°C and the night temperatures were high, which led to the growth of the zucchini. In this way, the farmers can not put down the straw curtain when they are in the shed. Instead, they can control the temperature by putting the straw curtain on the two thirds or the front face of the greenhouse. The straw curtain can also be put down, but the shed is ventilated. The mouth should be properly opened and the night temperature in the shed should be controlled at about 12°C to reduce the consumption of nutrients. During the day, if the temperature in the booth is higher than 22°C, the ventilation temperature must be reduced to a maximum of 25°C. Then spray the plant cationic activator to promote Kao No. 3, forcing the top quinoa essence nutrient backflow instead of hormone killing. This can not only inhibit the growth of squash, but also promote their reproductive growth, thus effectively controlling the growth of the squash.
For the zucchini that has already begun to produce melon, the vegetable farmer can control the daytime temperature in the shed at 20°C~22°C, control the night temperature at around 15°C, and spray the guttatine, thicken the guadi, and strengthen the nutrition orientation. Promote fruit development.
