The latest course of field management techniques and methods of yellow skin

Yellow bark is a small tree fruit of Rutaceae, which has been widely planted in the south of China with a long history. The whole fruit can be used to treat phlegm, cough and asthma, chest and diaphragm pain, leaf taste, soothing wind and relieving appearance, and root can treat stomachache and colic. Therefore, the edible value is very high, the cultivation of wampee pay attention to some management, the late maintenance of fruit trees is long-term, need to do a good job in the following aspects.

1. Fertilization

Base fertilizer can be applied after fruit harvest, and base fertilizer can be applied more, so 500 jin of farm compost or wheat bran leaching solution can be applied per mu. Generally, ditch application or furrow fertilizer application or annular ditch application is adopted, and hole application is better absorbed. But the first two methods are better to protect the tree roots, and the fertilizer effect can also be absorbed better. When topdressing is in the autumn shoot, it is necessary to apply fertilizer to promote shoot culture of fruiting branches, mainly applying quick-acting nitrogen fertilizer; before winter, topdressing is needed again, heat preservation and cold protection, generally, it is necessary to bury some rotten forage, usually about 300 jin per mu. 150 jin of compound fertilizer should be applied during flowering. In the end, we have to chase it again.

Second, water control

Flood water once a week before applying base fertilizer, keep the amount of water, and the soil still has 60% water content when applying the best fertilizer. Then it is necessary to cooperate with watering when fertilizing the autumn shoots, without flooding, plants can be drenched through. It is also necessary to flood water once before the beginning of winter, and it is not watered throughout the winter. This water has a heat preservation effect. Do not water during flowering to avoid aggravating physiological falling flowers. The fruiting period can be watered once a week or five days, but it can be decided by the soil.

Third, pruning and clearing the garden

Orchards usually have to cut off diseased fruit and diseased branches in real time or some old leaves, dense branches, withered branches or branches that grow upright and destroy the crown structure. Burn it centrally, then spray it. However, after fruit harvest, we should pay attention to the comprehensive cleaning of the garden, in addition to the usual tasks, but also trim short cut to retain the fruit branches, for many years of old trees, re-truncated roots to rejuvenate.

Fourth, thinning flowers and fruits

Generally speaking, there are many flowers in Rutaceae fruit trees, but not all of them can be retained, and many flowers can not completely set fruit, even if they set fruit, it is difficult to keep them, so the branches should be thinned first, and then the flowers endangered by diseases and insect pests must be removed. then, the flower organs should not be removed, and the flowers with the best clusters and suitable nodes should be kept. Thinning fruit is the excess fruit on the weak branch, the weak fruit on the strong branch, the diseased fruit, and the suitable node fruit.

V. Disease and pest control

The main control of anthracnose, caused by high humidity, can harm fruits, leaves, tender stems, branches and many parts. In general, in addition to timely cutting, it is also necessary to use 50% trimethoprim 500,600 times, or 75% chlorothalonil 700-1000 times. Mainly prevent white moth wax cicada, pruning, burning, and then spray or 10% dimethoate 2000 times liquid, or 40% dimethoate 1000 times liquid.

The main long-term task of wampee field management is the content of these aspects, so, management and maintenance should be as detailed as possible to do a good job of management, more agricultural content, please pay attention to the follow-up update.
