Kiwifruit orchards December-January-January-January The two most important farms are pruning and clearing in winter. The best order is to trim first. After that, all the plant residues in the garden will be cleared out of the park for centralized treatment. It is best to turn over the soil. Then the whole park sprayed lime sulfur mixture and finally tied the vine. Previously, we introduced in detail the knowledge and operation of winter pruning of kiwifruit female plants. Afterwards, we have detailed the relevant knowledge and specific operations of Qingyuan.
Entering the dormancy period of kiwi trees in winter, the pathogens and insects that are harmful to kiwifruit are also dormant. They mainly live in places such as diseased foliage, dead leaves, rotten fruit, subtilis, old bark, and shallow soil, and they Extermination is the most critical and effective preventive measure for diseases and pests next year. The most practical and feasible method for exterminating overwintering pathogens and pests is clear gardens. Clear Garden's specific operations are as follows:
1, clear the plant residues in the garden
Most wintering sites of pathogenic bacteria are decaying plant residues, such as branches cut by winter shears, leaves and stalks that remain on trees, old bark, fallen leaves, rotten fruit, and dried weeds. Clearing out of the park for deep burial or incineration can effectively reduce the sources of leaching.
2, loose the topsoil
If labor conditions permit, after the completion of the above work, before spraying the lime sulfur mixture, loosen the topsoil of the garden by 10-15cm to destroy the overwintering environment of pathogens and pests, and then combine with the lime sulfur spray agent, which can greatly improve the clean garden. Pest prevention effect.
3, spray lime sulfur mixture
The whole park sprays 3-5 degrees of lime sulfur, and the trees, weeds, soil, pillars, road trenches, fences or plants must be sprayed. When spraying the tree, spray it from the top to the bottom until the droplets flow. In layman's terms, it is equivalent to using a lime sulfur mixture to bathe the entire garden once.
