Fertile soil is a fundamental measure to fundamentally improve soil and fertility, which is to ensure robust growth of trees and good fruit development. Sapling between pear orchard, tree cover and overturning green manure are effective measures to cultivate pear soil in this period.
Zhuangshu is the key for pears to expand and mature, and can be used for biogas fertilizer. Each plant applies 50% of 60% biogas slurry and is applied every 15 days. After flushing, it is poured with appropriate amount of water. To control the application of nitrogenous fertilizers and increase phosphorus and potassium fertilizers, 100 kg of high-potassium compound fertilizer or 10 kg of high-potassium water-soluble fertilizer can be applied per acre. Fertilizer can also be sprayed at this time, can spray 0.3% ~ 0.5% of urea, 0.3% ~ 0.5% of potassium dihydrogen phosphate, for fruit trees with a deficiency, can be sprayed with 0.1% ~ 0.3% of borax , 0.5% of zinc sulfate and 0.3% to 0.5% of ferrous sulfate.
Rooting is the basic pear tree is the physiological drought tolerance of the tree species, a large amount of water, so timely irrigation. For low-lying pear orchards with high groundwater levels or pear orchards that have accumulated water in the rainy season, they must clear the ditch and drain the ditch in time. The pear orchards that have caused damage must loosen the soil accumulated in the tree plates in time, and properly break open the soil in the rhizosphere. Root 2 to 3 days to ensure normal breathing of the root system.
