September is the second swelling period of kiwifruit, and it is also the period when early-maturing varieties are about to mature. Kiwifruit should be supplemented with sufficient nutrients in time. During this period, the fruit trees are mainly supplemented with potassium and calcium. Potassium can promote fruit expansion and promote sugar. Calcium is mainly used to increase the hardness of the fruit, so that the fruit is resistant to storage and transportation. This period is still hot weather, it is reasonable to use the following methods to fertilize: One is to use flushing fertilization, which can be combined with irrigation for flushing; The second is to use the opportunity of rainfall to spray the flushing fertilizer on the ground or spread it throughout the garden to infiltrate the soil without deep turning. The third is foliar spraying. Two types of foliar fertilizers with high potassium content and high calcium content are used for mixed spraying, but due to limited absorption, they must be used three times, once a week, and there are many types of foliar fertilizers. You can choose imported potassium dihydrogen phosphate and good calcium fertilizer for foliar spraying. Disclaimer: Some articles on this website are transferred from the Internet.
