Measures of summer tube of golden pear

In the cultivation of golden pear, the low rate of excellent fruit is mainly due to more deformed fruit and pericarp fruit. Summer management is a key period to improve fruit quality. The main technical measures are introduced as follows:

The main results are as follows: 1. The fruit expansion period is from mid-June to late August, and the golden pear needs more water. In the case of drought, if the pear shrinks and wrinkles during the day and absorbs water at night, it can recover or grow, otherwise the fruit is small or wrinkled all the time. In late July, if there is no rain for a long time, different degrees of fruit cracking often occur. Therefore, during this period, according to the weather conditions and soil moisture, continuous irrigation, in order to increase the fruit and prevent the production of toad skin. Golden pear is more resistant to waterlogging, but it should be drained in time after a long rain.

In the middle of June, fruit expansion fertilizer should be applied. Generally, 1.5-2kg compound fertilizer should be applied to each tree, depending on the size of the tree. The shooting ditch should be opened and watered after sprinkling. The first ten days of July is the beginning of rapid fruit expansion, foliar fertilizer should be applied, nitrogen fertilizer should be controlled, and potassium dihydrogen phosphate should be sprayed 0.1-0.2 kg per tree to improve fruit quality.

3. Prevention and control of diseases and insect pests is an important guarantee to increase the yield of golden pear. The main diseases from June to August were scab, brown spot, ring rot and so on, and the main pests were pear heart borer, beetle, wood lice, pear aphid, red spider and so on. The control method is to spray carbendazim + abamectin (or pyrethroid) in the middle of June. Spray imidacloprid + Fen Ning in early July and mancozeb + Taoxiaoling in late July. Spray Surel + carbendazim in the first ten days of August. At the same time, can hang sugar and vinegar solution to kill pear heart borer, beetle, pear aphid and so on.

In April and early June, the top of the spring shoot stops growing, and summer pruning, coring, thinning and pulling branches should be carried out, so as to prevent poor ventilation due to dense canopy branches and leaves. In the young fruit stage, it is easy to produce fruit when there is too much water and high humidity in the air. The general number of branches is 1000 to 2000 per plant.
