First, the requirements of zucchini on temperature conditions
The optimum temperature for the growth and development of zucchini is 18 ~ 25℃. If it is below 15℃, it will grow slowly, and basically stop growing below 8℃, while if the ambient temperature is above 30℃, it will also grow slowly, which is prone to viral diseases.
In different growth stages, zucchini has different requirements on temperature.
◆ The optimum temperature for pumpkin seed germination is between 25℃ and 30℃. When the temperature is lower than 13℃, it is not easy to germinate. When the temperature is higher than 35℃, the bud is very thin, but it is not easy to grow into a strong seedling.
◆ The optimum temperature for the flowering and fruiting period of zucchini is 22 ~ 25℃. When the temperature is lower than 15℃, it is not easy to fertilize, or there are many abnormal melons. When the temperature is lower than 10℃, the growth stops, and when the temperature is higher than 30℃, the flowers of zucchini can't develop normally and are easy to be infected with virus diseases.
◆ The optimum temperature for the development and expansion of zucchini is 22 ~ 30℃.
◆ The growth of pumpkin roots also needs temperature, and the minimum ground temperature should be above 12℃. When the temperature is lower than 12℃, the root system will develop slowly or not at all, and it will be damaged in severe cases. If zucchini seedlings are trained at low temperature, they can tolerate the low temperature of 0℃ in a short time.
Generally speaking, in the growing season of zucchini, the daytime temperature is about 25℃, and the most suitable temperature at night is about 15℃.
Second, the requirements of zucchini for light conditions
Zucchini prefers plenty of sunshine, but it is also more tolerant of weak light.
◆ At the seedling stage of zucchini, sufficient light can promote the first female flower to open early, and then it can bear fruit early.
◆ Sufficient sunlight during the fruit-bearing period of zucchini can reduce the appearance of melons, which is beneficial to the rapid growth and expansion of melons.
The length of light time also affects the growth and development of zucchini.
The seedling stage requires 8 ~ 10 hours of light every day. Short sunshine is beneficial to the early differentiation and development of female flowers of zucchini, and of course, it can also bloom and bear melons early in the future. But it should also be noted that the shorter the illumination time, the better. If the light time is a little more than 7 hours a day, the growth of seedlings will not be very good.
During the flowering and fruiting of zucchini, long-term illumination (daily illumination time is 1 1 hour) is very beneficial to flowering and fruiting. Another point is that long-term light every day can also make up for the adverse effects of insufficient light intensity on the growth of zucchini.
When cultivating zucchini in solar greenhouse, it is usually required to uncover the straw cover in the morning and cover it as much as possible at night to prolong the illumination time, but it should be noted that the longer the illumination time, the better. If the daily light time exceeds 18 hours, the zucchini will not sit on the melon.
Third, the requirements of zucchini for water conditions
Because the root system of zucchini is relatively developed, it also has strong water absorption and drought resistance. Everyone knows that the leaves of zucchini are relatively large, and a lot of water will be lost through the leaves, so its drought resistance is relative. Zucchini prefers an environment with wet soil but dry air, especially in arid areas with irrigation conditions. Pay attention to the fact that zucchini should not be watered too much at the beginning of fruit. If irrigation is too much, it will easily lead to excessive growth (that is, crazy seedlings), which will affect melon sitting. Pumpkin needs a lot of water during the expansion period, so it should be watered in time. However, if it is cultivated in a protected field, it should be ventilated in time after watering to eliminate moisture and reduce air humidity, otherwise it will cause other diseases of zucchini.
Fourthly, the requirements of zucchini on soil conditions.
Zucchini is most suitable for planting in loam with good aeration and strong water and fertility conservation. However, because the root system of zucchini is relatively developed, its ability to absorb water and nutrients is also relatively strong. It can grow normally in sandy soil or cohesive soil, and sometimes even in mild saline-alkali soil, as long as more farmyard manure is applied, better yield can be obtained.
Five, zucchini requirements for fertilizer conditions
Zucchini has a strong ability to like fat. Too much nitrogen fertilizer will easily lead to the virtual growth of stems and leaves, which will lead to the flowering, melon melting or disease of zucchini. Therefore, attention should be paid to the reasonable collocation of nitrogen, phosphorus and potassium fertilizer when applying fertilizer, and it should be applied several times at the right time. The demand for fertilizer in the early growth stage of zucchini is relatively small, mainly because the demand is relatively large after entering the fruiting stage, and the demand for potassium fertilizer is obviously increased.
When applying fertilizer, it is required to give priority to farmyard manure with a small amount of compound fertilizer. In the early flowering stage of pumpkin, a small amount of nitrogen fertilizer can be topdressing according to the plant growth. After entering the fruiting period, nitrogen fertilizer should be topdressing regularly. After the melon bears fruit in the middle and late stage, we should pay attention to increasing the amount of potassium fertilizer and phosphorus fertilizer, and if necessary, we can apply potassium dihydrogen phosphate and other topdressing to the leaves.
The above are the requirements for the growth conditions and environment of zucchini. I hope I can help you. If you have any questions, you can also leave a message in the comment area, and we will discuss it together.
