The weather changes greatly in early spring. What is the management method of kiwifruit production in early spring?

Kiwi is a perennial vine, which grows vigorously and bears early fruits. Kiwifruit plants selectively absorb soil nutrients. For example, kiwifruit plants have high chlorine content and high demand for iron, which easily leads to soil nutrient imbalance. Generally, it blooms from May to June and matures in September-10. After beginning of spring, kiwifruit entered a new year's growing season. From early spring germination to flowering, fruiting and harvesting, water and fertilizer management must be in place to ensure the high yield of kiwifruit and the healthy growth of trees.

Generally, it is divided into spring fertilization (germination stage), flowering stage, fruiting stage and confinement stage, which can be compared to the nutritional needs of men and women during pregnancy and the nutritional supply of women during the first, second and confinement stages. Each stage needs nitrogen, phosphorus and potassium, and the demand ratio is different. Combining soil, water source and kiwifruit, it needs water and is afraid of waterlogging, so it belongs to a fruit tree with weak physiological drought tolerance and moisture tolerance. So when watering, it should be decided according to the actual situation. Water it when it is dry, and water it frequently to keep the soil moist. If the rain is too heavy, drainage should be carried out in time.

The watering of kiwifruit in spring is mainly divided into three stages: germination stage, before flowering and after flowering. Because kiwifruit has a high demand for water during germination, especially in the north, there is not much rain at this time, so watering is needed at this time to meet the water demand of kiwifruit germination. In spring, kiwifruit can be watered about a week after flowering, that is, sitting on the fruit and watering it. Now drip irrigation and intelligent drip irrigation are advocated, and fertilizers and medicines can also be washed through drip irrigation.

Prevent early spring frost and late frost, kiwifruit producing area in spring. Late frost and freezing injury occur frequently. Especially some orchards in low-lying areas. The freezing damage is more serious. It is necessary to do a good job of prevention in time. Pruning is only done in summer and winter. Summer pruning is mainly to cut off long branches, long vegetative branches or long fruiting branches. In winter, the old branches and fruiting branches are mainly updated or cut off to promote the germination of healthy new shoots in the coming year.
