Kiwi fruit is a berry-like vine tree, and it is a new fruit with high nutritional value. The edible value and medicinal value of its fruit are very high, and the cultivation area has expanded year by year in recent years. Kiwifruit grows vigorously, with luxuriant branches and leaves, and the results are many and early. It consumes a lot of nutrients every year, and it needs the soil to supplement effective nutrients in time to meet its growth and development needs.

Base fertilizer: The period of fertilization is generally from October to November. After the fruit is picked, a large amount of nutrients are lost in the leaves, and timely supplement of nutrients is beneficial to increase the nutrient level stored in the tree, and promote the differentiation of flower buds before and after deciduous leaves and a period of time before flowering the following year. Apply 5--8 kg of bio-organic fertilizer to young trees; apply 8--12 kg of bio-organic fertilizer to adult trees in their full fruit period.

Top dressing: Top dressing in time according to the growth characteristics of the kiwi root system and the growth phenology period of the above ground. The saplings are top dressing with a small amount of multiple times. Generally, from before and after germination to July, apply 1 kg of bio-organic fertilizer per month; Topdressing three times.

The first time was in early spring to promote bud fertilizer. Before and after germination from February to March, 3-5 kg of bio-organic fertilizer is applied to the plant to promote the germination of axillary buds and the growth of branches and leaves, and increase the fruit setting rate. The second time is to promote fruit fertilizer after flowering. 30-40 days after flowering is the period of rapid swelling of kiwi fruit, and lack of fertilizer will hinder kiwi fruit's swelling. The fruit-promoting fertilizer should be applied 20-30 days after flowering, and 2-3 kg of bio-organic fertilizer should be applied. Midsummer strong fruit fertilizer: In order to enrich the fruit, increase single fruit weight and improve quality, topdressing phosphorus and potassium fertilizers are applied once in June to July. You can also use 0.5% potassium dihydrogen phosphate, 0.3%-0.5% urea solution and 0.5% calcium nitrate foliar spray.
