During the period of rapid pear fruit expansion, fruit growers should achieve the "three in one" of fertile soil, strong trees and roots. This is not only related to the improvement of the quality and efficiency of the pear fruit that year, but also the output and income of the pear orchard in the following year. Fertile soil is fundamental For pear orchards with grass growing between rows, at this time it coincides with the same season of rain and heat, and the grass grows luxuriantly. The grass with a growth height of 30-40 cm should be mowed in time, and the stubble height should be 10-20 cm, and the rain is abundant. Keep short stubble in areas and high stubble in arid areas. The mowed grass directly covers the tree tray. During this period, soil microbial activities are vigorous, and organic materials such as straws decompose faster. Various crop straws (such as corn, rice, wheat, bean straw, etc.), weeds, and discarded branches pruned in summer in the orchard can be covered in the tree trays. For organic materials, the thickness of the cover should be 15 cm, and the root neck should not be covered within 20-30 cm, so as to avoid waterlogging and suffocation and rot of the root neck. For pear orchards where green manure crops such as sesame seeds, vetch and alfalfa are grown, in-situ pressing can be carried out at a depth of 10-15 cm; fertilization trenches can also be dug in the row to cut the green manure crops. Press into the fertilization ditch, the pressing amount of green manure for 1-3 year-old young trees is 3 to 5 kg, and the pressing amount of green manure for big trees in full fruit period is 20-25 kg. Strong tree is the key Fertilization is a key measure to ensure the healthy growth of the tree. During the pear fruit swelling period, it can be flushed with biogas slurry fertilizer, each plant flushed with 5 kg of 60% biogas slurry, flushed once every 15 days, after flushing, watered with appropriate amount of water. This period is the critical period for the growth of new shoots, the differentiation of flower buds and the swelling of fruits. To control the application of nitrogen fertilizer and increase the application of phosphorus and potassium fertilizers, 100 kilograms of high-potassium compound fertilizer or 10 kilograms of high-potassium water-soluble fertilizer can be applied per acre. At this time, leaf fertilizer can also be sprayed, 0.3% to 0.5% urea, 0.3% to 0.5% potassium dihydrogen phosphate can be sprayed, for fruit trees with nutrient deficiency, 0.1% to 0.3% borax can be sprayed as appropriate , 0.5% zinc sulfate and 0.3% to 0.5% ferrous sulfate.
