The plan of the year lies in the spring management of Hongyang kiwifruit in spring.

Hongyang kiwifruit, fruit core like the sun, red meat type, very early varieties, in recent years, popular growers favor, has been widely introduced. But there is no scientific management method, and there is no expected benefit. Therefore, we must do a good job in the cultivation and management of kiwifruit every spring.

Hongyang kiwifruit spring tube

1) Timely watering. The water requirement of Hongyang kiwifruit in spring is very large to meet the needs of germination, shoot, leaf development, flowering and fruit setting. When the water content in the field is lower than 75~80%, it must be watered in time. At the same time, attention should be paid to waterlogging prevention and drainage, and the ditches of the garden should be cleaned to avoid ponding in the garden.

(2) Fertilization in spring. On the basis of good application of autumn base fertilizer. 15 days before the kiwifruit germinates, the spring fertilizer is applied once in combination with irrigation, and is determined according to tree vigor, age, soil fertility and water content, and the quick-acting fertilizer is mainly used, and the ratio of nitrogen, phosphorus and potassium required is 4:2:1. 150- 200g urea, 250g calcium superphosphate and 100- 150g potassium chloride are applied to each plant, and 80- 120kg water is applied to each plant. When seedlings germinate, dressing germination fertilizer is critical, it can promote more and better spring shoots, adult trees per plant dressing: urea 150~200g, calcium superphosphate 400~500g, potassium chloride 100~150g.

(3) Seedling pruning. 2-3 plump and healthy buds are selected and reserved on the mating interface of the seedlings planted in spring for pruning, and the pruning is finished before germination.

(4) Sparse flower buds. Hongyang kiwifruit flower rate is high, early bud thinning, can save nutrients. When the flower bud grows to the pea grain big, start thinning the bud, combine thinning the bud, and prune the branch at the same time. Before thinning branches, first distinguish between fruit branches and vegetative branches. The branches that are drawn out on the fruit mother branches and can bear fruit are called fruit branches, and the branches that do not bear fruit are called vegetative branches. The bud branches with few leaves or no leaves, the buds and twigs on the trunk, the first and last bud on the fruiting branch, and the flower buds with diseases and insect pests are all removed.

(5) Flowering management. The flowering period is about mid-late April. It is suggested that artificial pollination should be carried out for self-flowering and difficult breeding of kiwifruit. Artificial pollination can be done by dry powder method and liquid method. Dry powder method is to stick the prepared pollen with cotton ball or chicken brush after 8:00 in the morning, and gently touch the stigma of female flower. Each dip can give 5-10 flowers. Liquid teaching method: glucose: borax: water: 5:3:2:20 mix well, so that pollen fully suspended in water, operation method as above. In spring drought areas, liquid method is recommended. 3-5 days before pollination, bud thinning and flower thinning can be carried out according to the load amount, and fruit leaf surface can be sprayed with fruit and fruit strengthening spirit liquid at full flowering stage to increase nutrient transmission amount and self-regulate nutrition matching.

(6) Pest control. (1) The ability of resistance to canker disease of Hongyang kiwifruit is weak. In addition to strengthening tree management and enhancing resistance, pesticide + tree protection general should be sprayed timely before and after germination in spring to prevent pests from biting bark and bud tip and preventing disease invasion. If it has occurred and the disease is serious, cut off the diseased branches and burn them. The tree protector can be sprayed on a large scale to form a protective film, suffocating sterilization and preventing germs from being infected again. (2) For root rot and root rot disease, root irrigation can be used to kill soil pathogens in winter and spring, and soil-borne pathogens can be controlled by digging and drying roots in growing season.③ Red sun resistance is weak, spraying pesticides and foliar fertilizer, the concentration should not be too large.

In a word, the plan of a year lies in spring. Only by doing well spring management can we lay a good foundation for the high yield of Hongyang kiwifruit.
