First, excellent construction of the park: Although the crystal pear is drought-resistant, cold-resistant, thin-resistant, and highly adaptable, it is necessary to choose the best cultivated land for efficient cultivation. The soil layer of the cultivated pear must be deep, and the soil should be fertile. It is rich in organic matter. Sandy loam or loam is the best cultivation soil. It is best to have a certain amount of irrigation and drainage capacity. The terrain should be flat and should be avoided at the ridges and tuyere.

Second, to be equipped with adequate pollination varieties: crystal pear pollen, and fortunate water, July crisp strong affinity, pollination varieties are insufficient, the crystal pear fruit set rate is low, a small fruit, poor quality, and therefore in the cultivation to have sufficient The pollination varieties to improve the fruit setting rate and fruit quality, pollination varieties should account for more than 20% of the total number of plants.

Third, it should be closely planted: Crystal pear into the early stage of results, Shuzi slightly upright, weak budding, into the branch medium, suitable for close planting, in the production should be close planting, to promote the rise of early production, can be used 2 meters 4 meters Or 2 meters 3 meters of row spacing cultivation, in order to increase the coverage as soon as possible, increase the accumulation of photosynthate and promote premature birth.

Fourth, the sapling period should pay attention to open angle, branching: crystal pears weak budding, into the branch medium, slightly stand upright in the tree, in the sapling period should pay attention to opening angle, in order to ease the branching potential should be appropriately increased short cut pruning The proportion of stimulating growth, increasing the amount of branches, increasing coverage, and increasing material accumulation.

5. To prevent tree vigor from weakening: Crystal pears are prone to excessive results, resulting in debilitating tree vigor. In the production, it is necessary to prevent the phenomenon of declining tree vigor. The debilitating tree vigor, on the one hand, results in excessive results, leading to a large consumption of nutrients in the tree. On the other hand, lack of nutrition, and on the other hand, the result is that the branches are not updated in time, and the aging phenomenon is severe. Therefore, to prevent the tree vigor from weakening, we should proceed from the following three aspects:

1. Strictly control the load: The output of the mu should be controlled at about 3000 kg, and the surplus flowers should be removed promptly.

2. Timely supply of nutrients: 3,000 kg of high-quality farmyard fertilizer is used as the base fertilizer each year after fruit harvesting. Before germination, the quick-acting chemical fertilizers are applied in June and the expansion fruit period to supplement the nutrients. The level of yield and soil fertility depend on the standard of producing 100 kg of fruit, 0.5 kg of nitrogen, 0.2 kg of phosphorus, and 0.3 kg of potassium.

3, to strengthen the update of pruning: in the production of three sets of branches to be used to trim, the results of the control of the age of the branches within 2-3 years, the aging results of more than 3 years, the branches should be updated, each year to grasp the updated branch accounted for the total Approximately 1/3 of the branch amount maintains the dynamic balance between the result branches, squid branches and auxiliary branches, preventing tree vigor from weakening.

Six, we must strengthen the prevention and control of pests and diseases to ensure high yield and high quality: Crystal pear is more resistant to disease, especially for the black pear, anthrax, and ringworm disease, which is a serious threat to pear production. However, it is prone to fruit rust. Insect pests are mainly maggots, beetles, scale insects, carnivores, pear stem bees and other hazards. Prevention and control should be strengthened in production. Pest diseases and pests should be mainly prevention. Before the budding, the lime sulfur can be sprayed once for 5 times. In order to kill overwintering pathogenic eggs and reduce the number of disease and insects overwintering base, lay a solid foundation for prevention and control throughout the year. In the first month after flowering, bagging is carried out to protect the fruit surface to prevent the occurrence of fruit rust and harm to the fruitworm. Leaf diseases should be promptly sprayed to prevent and treat the young urea No. 3 and the enemy to kill to prevent harm.
