The zucchini is a thermophilic vegetable, and the seeds begin to germinate above 13°C, and the seed germination is most favorable at 25-30°C. The suitable temperature for its growth is 18-25°C, and the temperature requirement during flowering is higher than 15°C. The squash is not tolerant to high temperatures, and the flower growth rate is higher than 32°C. When the temperature is below 11°C, the growth stops at above 40°C. After the low-temperature hardening, the seedlings of the zucchini seedlings can tolerate a low temperature of 0° C. for a short period of time during early colonization and survival. Compared with common melons, the zucchini seedlings are tolerant of low temperature ability.
Zucchini is a short-day crop, and the temperature and length of the seedling period have a great influence on the appearance of female flowers in the summer and evening and female flowers. Therefore, in early spring cultivation can be early nursery, promote early melon. Zucchini grows well under well-lit conditions, with thick stems and thick leaves. However, under conditions of high temperature, high humidity, and lack of light, they often cause leggy, plant weakness, internode elongation, thin leaves, susceptible to disease, and affecting sitting. melon. Zucchini has a strong adaptability to strong light, and under other suitable conditions, it also has a certain tolerance to weak light.
Zucchini does not require strict soil conditions. Both sandy loam and clay loam grow normally, but it grows best in fertile neutral or slightly acidic (pH5.5-6.8) sandy soil. Zucchini has a well-developed root system, many lateral roots, rapid growth, and strong absorptive capacity. This is a manifestation of its strong drought tolerance; the roots of zucchini are mainly distributed in the topsoil of the soil surface. As the general cropping layer is shallow, the water storage and storage are shallow. Limited capacity, often easy to dry, de-fertilizer, coupled with the stalks of squash, lush foliage, large leaves, strong transpiration, so the production should pay attention to maintain the appropriate soil moisture content. The suitable soil moisture content is 50% -60%, the soil moisture content is too high, it is easy to cause leggy. In the cultivation of greenhouses, soil moisture is often too large, causing leggy and affecting melons. Zucchini has a large demand for soil nutrients. If the cultivated land is too barren, a large amount of fertilizer should be applied to obtain a satisfactory yield. Due to the concentration of squash and squash, the application of nitrogen fertilizers should be emphasized in the early stage of growth to promote plant growth. If de-fertilization occurs, the melons are small and irregular in shape, affecting the quality and yield of the product.
