There are many areas of zucchini planted, and it has the name of small melon, white melon, melon, and melon. Zucchini is rich in vitamin C, glucose and other substances, many people like to eat. Let's take a look at the cultivation techniques and pest control of the zucchini. First, the requirements for growth conditions of zucchini The optimum growth temperature of zucchini is 20-25 °C. If it is below 15 °C, it will grow slowly. When the temperature is lower than 8 °C, it will stop growing. At the same time, 25-30 °C is the suitable temperature for germination of zucchini seeds. It is prone to length and germination slowly above or below this temperature range. Zucchini is moist, not tolerant to drought, virus disease is easy to occur under high temperature and drought conditions, and high temperature and high humidity are also likely to cause powdery mildew. The soil requirements of the zucchini are not strict, and the sand, loam and clay can be cultivated, and the loam with deep soil is easy to produce high yield. Second, the cultivation technology of zucchini 1. Soil preparation and fertilization Mainly organic fertilizer, add cake fertilizer + compound fertilizer + grass ash, then spread the fertilizer evenly on the ground, deep turn 30 cm, level the ground. After the fixed value, the two parts of the rosette period - three leaves began to topdress, using a small amount of multiple methods. 2, trenching and tidying Mostly adopt deep sorghum and mulch to cover cultivation. The width of the ridge is about 100cm and 20cm respectively, and the width of the groove is about 20cm-30cm. Weeds can be applied to the herbicide before the film is covered. Care should be taken to tighten the cover film and then compact it with soil. 3, colonization In general, the seedlings can be colonized in a month or so at the age of 3 leaves. The time is in mid-March, the seedbed is watered one day before planting, the seedlings and seedlings are selected, and the roots are transplanted as much as possible. When the planting is done, the roots should be stretched normally. The roots should be poured and fixed with fine soil. The cover is tight, and the water is poured once a day after the meal until the seedlings survive. 4, temperature The slow seedling stage can be properly ventilated, then increase the indoor temperature of the greenhouse and promote root growth. The temperature in the greenhouse is best maintained at 25-28 ° C during the day and 15-20 ° C in the evening. When the indoor temperature in the greenhouse exceeds 30 ° C It is necessary to cool down the ventilation. Appropriate reduction in temperature after slow seedling is beneficial to the differentiation of female flowers and early sitting. After the fruit is set, the temperature should be increased, 22-26 °C during the day, 12-17 °C at night, and at least 10 °C. 5, fruit and fertilizer water After the spring, artificial pollination should be carried out. The pollination time is usually before 9:00 on the same day. The male flowers opened on the day are removed, the corolla is removed, and the female flower stigma is gently applied. In addition, the fertilizer can be applied in a large amount, or a little foliar fertilizer is sprayed, and the watering is determined according to the soil condition. Third, pest control Powdery mildew: imipenem, flusilazole. Viral toxicity: morpholinium hydrochloride (treatment), sinamide (prevention). Downy mildew: chlorothalonil (prevention), imipenem (treatment). Gray mold: iprodione, violacein. Aphids, whitefly mites: imidacloprid, acetamiprid, clothianidin. Red spider: avermectin, scorpion, guanidine, thiazolone. Liriomyza: avermectin, chlortetracycline. The above is the introduction of the cultivation and management technology of zucchini. As long as the above points are completed, the yield and quality are guaranteed.
