The demand for nitrogen, phosphorus, and potassium of zucchini was the most potassium, nitrogen and phosphorus. In spring and summer, the temperature is high, and the zucchini grows vigorously. If the nitrogen fertilizer is too much, it can easily cause leggy squash, vegetative growth and reproductive growth disorders, causing melons. Therefore, at the turn of the spring and summer, the zucchini dressing must pay attention to less nitrogen fertilizer, mainly based on high potassium compound fertilizer.
Zucchini is not heat-tolerant, and high-temperature drought not only reduces the yield but also induces viral disease. The temperature is high. If the ventilation and watering are not timely, it will easily lead to high temperature and drought, resulting in the occurrence of virus disease. In addition, the high temperature of squash is easy and prolonged, causing melons. Therefore, in the spring and summer, when the drought in the field should be watered in time, after the watering, timely cultivation of loose soil.
Zucchini should pay attention at any time during the cultivation process to remove lateral buds and lateral branches, in the period of fruiting melons to prevent too much results and falling pods, generally 2 leaves and 1 melon as an appropriate amount of fruits to carry out fruit thinning. In the later period of the squash, old leaves and diseased leaves should be promptly blown to promote ventilation.
VTM sampling kits are designed for the collection, preservation, and transport of viruses, chlamydia, mycoplasma, and ureaplasma urea. They are now widely used for sampling and transporting prior to virus detection. MandeLab's VTM kits provide a safe and convenient way to collect and transport virus samples.
