Sufficient water and fertilizer supply. Fertilization for walnuts is divided into base fertilizer and top dressing. The base fertilizer should be done early and should be completed after harvest and before deciduous. Apply 100-200 kg of high-quality organic fertilizer to each adult tree. Topdressing is applied during the walnut growth period. The first topdressing is applied before germination, 1500 kg of pig manure water and 20 kg of urea are applied per mu; the second topdressing is applied during the hard-core period (June to July) to help increase fruit weight and weight. To promote flower bud differentiation, 2500 kg of pig manure water, 30 kg of urea, 20 kg of potassium sulfate and 20 kg of superphosphate can be applied per mu.
Foliar spraying nutrient solution Spray 0.3%~0.5% urea plus 0.3% potassium dihydrogen phosphate solution before flowering, young fruit stage and fruit expansion stage of walnut trees, and 0.1~0.2 kg of urea on the plant , Supplement the nutrients needed for fruit growth and improve the quality of grouting.
Enhancing tree vigor In the middle and late stages of walnut fruit setting (July to August), high temperature and drought are often encountered, which affects the quality of walnut fruit grouting. You can spray 800 times the "new high-fat film" emulsion, and spray again every 10 days to resist drought , Moisture preservation, water resistance and transpiration, strengthen tree vigor.
Proper pruning and pruning should be combined with scion picking, with short cuts as the mainstay. The length of the branches should be up to 3 cm, and the outer or lateral buds should be kept, and the layer spacing should be reserved; the dense branches should be thinned out and the hanging branches should be retracted. After cutting, the wound must be protected to prevent the tree from being weakened by pests and diseases, and the wound should be protected with a "wound antiseptic film" to prevent dryness and water evaporation.
Timely prevention of diseases and insects During the growth period of walnut trees, it is necessary to prevent and control diseases and insects, reduce the bearing capacity of the tree, and concentrate nutrients to supply flowers and fruits. During the growth period, spray "General of the Trees" + spray 1:0.5:200 times Bordeaux mixture, or use 50% thiophanate methyl wettable powder before flowering, after flowering and young fruit stage.
