Pears during the fruit expansion period
August is the period when the late-ripe pear fruit is rapidly expanding. The fruit grower should achieve fertile soil, strong trees, and rooting. This is not only related to the improvement of quality and efficiency of pear fruit in the year, but also related to the output and income of pear garden in the following year. Fertile soil is fundamental The improvement of soil and fertility are the fundamental measures to ensure the 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. For the pristine pear garden, this time coincides with the rain and heat in the same season, the grass grows lushly, and the grass that grows 30-40 cm in height must be castrated in time, and the height of the cut is 10-20 cm. In areas rich in abundance, dwarf locusts are appropriate, and arid areas are properly maintained. The cut grass is directly covered in the tree tray. During this period, soil microbiological activities are vigorous, organic materials such as straw are decomposed faster, and various types of crop stalks (corn, rice, wheat, bean stalks, etc.), weeds, and waste branches of summer pruning in orchards can be covered in the tree trays. Materials, covering the thickness of 15 cm is appropriate, do not cover the root neck around 20 to 30 cm, so as not to accumulate phlegm caused by root rot suffocation. For orchards planting green manure crops such as sesbania, wolfberry fruit and alfalfa orchards, the local pressure can be turned over at a depth of 10-15 cm; digging fertilization ditch can also be used to dig green manure crops in rows. Pressed into the fertilization ditch, 1 to 3 years old young tree green manure inflicted 3 to 5 kilograms, full fruit tree green manure into the pressure of 20 to 25 kilograms. Strong tree is the key Fertilization is a key measure to ensure the robust growth of trees. During the expansion period of pear fruit, biogas fertilizer can be used to flush and apply 50% of 60% biogas slurry to each plant, flushed once every 15 days, and then flushed with appropriate amount of water. This period is at a critical time for the growth of shoot length, flower bud differentiation and fruit enlargement. To control the application of nitrogenous fertilizer and increase the application of phosphorus and potassium fertilizer, 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, spraying 0.3% to 0.5% urea and 0.3% to 0.5% potassium dihydrogen phosphate. For fruit trees with a deficiency, spray 0.1% to 0.3% borax, 0.5% zinc sulfate, and 0.3% to 0.5% ferrous sulfate can be sprayed as appropriate. Rooting is the foundation Pear is a tree species with poor physiological drought tolerance and requires a large amount of water. This period is the critical period of water requirement for pear trees, and the root system (especially the shallow root system) is susceptible to high temperature and drought. Therefore, proper irrigation should be performed timely and properly. The normal growth of the tree and the rapid expansion of the fruit. 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.
