How to grow high quality Yali pear?

How to grow high-quality pear? If you want to grow high-quality pear, please refer to the following pear planting methods: 1. Apply basal fertilizer early, increase phosphorus fertilizer, control nitrogen fertilizer, and ensure three waters. (1) Early application of base fertilizer: In the past, the traditional application of base fertilizer should be advanced to the autumn fruit harvest (September-October). Because at this time the fruit tree nutrition consumption has been very large, the root system will appear the last growth peak of the year, early application of appropriate base fertilizer, can achieve tree nutrition deficiency, restore tree vigor, enrich flower buds for the next year to lay the foundation for flowering. (2) Increasing phosphorus fertilizer: increasing the amount of phosphorus fertilizer applied when applying base fertilizer and topdressing can obviously improve the quality of Yali pear. Generally, 0.3 kg of pure nitrogen is applied per 100 kg of fruit, and the fertilizer ratio of nitrogen, phosphorus and potassium is 1: 1.5: 1. Topdressing is applied twice in the whole year, once before germination (in the middle and late March) and once during the young fruit expansion period (in May). (3) Control nitrogen fertilizer: nitrogen fertilizer should be fully applied before wheat harvest (before June), controlled after June, and excessive nitrogen fertilizer application in the later period will cause fruit quality to decline and flavor to fade. (IV) Ensure three waters: water three times a year in combination with fertilization in general years, and irrigate thoroughly. After wheat harvest weather conditions such as persistent drought can be watered again. Control watering from July to September. II. Grass covering under trees to increase fat and moisture Covering trees with grass before the rainy season can keep soil moisture and inhibit weed growth. After straw rot into the ground, can increase soil humus, improve soil structure, improve soil fertility, promote pear growth and development. III. Reasonable pruning, adjustment of tree vigor and illumination The tree in full fruiting period is mainly to adjust the branch group, control the tree height not to exceed 3.5 meters, open the hierarchy to solve the illumination, make the large, medium and small branch groups evenly configured, and renew and rejuvenate the weak branch group. IV. Artificial pollination, flower thinning and fruit thinning shall be carried out, and the fruit retention index shall be strictly controlled. (1) Artificial pollination: Pollen of Guangli and Xuehua pear is the best pollination combination of pear varieties, not only the pollen quantity is large, the affinity is strong, but also the fruit color is good, and the quality is good, which is better than other pollination varieties. Pollen should be collected 2 - 3 days before flowering. Yali pear has strong fertilization ability within three days after flowering, so artificial pollination should be carried out during this critical period within three days after flowering, and it is better to carry out artificial pollination in the morning. (II) Thinning flowers and fruits: Generally, thinning flowers begins at the inflorescence separation stage, thinning fruits begins two weeks after flower drop, and is completed before the end of May. 5. Bagging period of pear generally starts from May 20 after thinning fruit, and ends before June 10. Before bagging, spray the pesticide mixture once, and bag at the same time. When bagging, the bag mouth should be close to the base of the fruit stalk, tightly tied, but do not hurt the fruit stalk to prevent the fruit from falling off. It is better to use double-layer black paper bags. Click for more pear planting technology Click for more fruit planting technology
