When the method of applying fertilizer is lack of potassium, the fruit is small.

Turn it for 30 cm deep, and make it into a flat field border(plug tray nursery). After the water seeps dry, scatter the dry seeds to cover the fine soil for 1 cm, and the sowing amount per mu is about 1 kg, and water in time after planting.
Due to not paying attention to the problem of drug use under high temperature and drought, water the seedlings in time before and after slowing down(40 cell plug tray wholesale). The metabolism of crops is also strong, which is conducive to the penetration of chemicals into their tissues and easy to produce drug damage(4.33inch plastic nursery pots).
