In the golden pear planting, the rate of good fruit is not high, mainly malformed fruit and rusty fruit. Summer management is a critical period for improving the quality of fruit. The major technical measures are now described as follows:
1, from the middle of June to late August is the period of fruit enlargement, the gold pears need more water. Under drought conditions, pears shrink wrinkled skin during the day and supplement with water at night, then they can be restored or increased. Otherwise, the fruit is small or wrinkled skin is always formed. In late July, if there is a long period of drought and no rain, fruit cracking occurs in varying degrees. Therefore, during this period, depending on the weather conditions and soil moisture, continuous irrigation, in order to facilitate the increase of fruit and prevent the production of molting fruit. Golden pear is more resistant, but it should be drained in time.
2. In mid-June, fruit enlargement should be pursued. Generally, 1.5 to 2 kilograms of compound fertilizer is applied to each tree, depending on the size of the tree. Open the ditch and water after spreading. Early July is the beginning of fruit rapid expansion, to recover foliar fertilizer, control of nitrogen fertilizer, usually spraying potassium dihydrogen phosphate 0.1-0.2 kg per tree, in order to improve fruit quality.
3, prevention and control of pests and diseases is an important guarantee for raising the output of Golden Pear. The main diseases in June-August were black spot disease, brown spot disease, and ring rot, and the main pests were Pyrosphaeridae, Scarab, Mudu, Pear-tree, and Starscream. The control method is: spraying carbendazim + awei insect clear (or pyrethrin) in mid-June. In the first half of July, imidacloprid + triadimefon was sprayed; in the second half of July, mancozeb-zinc + peach sow was sprayed. In the first half of August, the sweep + carbendazim was sprayed. At the same time, sweet vinegar can be hung to kill pear pests, beetles, pears, etc.
In early June, the top of the spring shoots will stop growing. Summer pruning, picking, thinning, and pulling branches are needed to prevent poor ventilation due to dense foliage and branches. In the young fruit period, fruit rust is likely to occur due to excess water and high humidity. The average branch weight is 1000-2000 pieces per plant.
