Apricot tree harvest management
First, soil and fertilizer management
1. The apricot fruit should be combined with weeding after harvesting, and the whole garden is subjected to one-time cultivating loose soil, and the cultivating depth is generally about 10 cm. Before deciduous, the basal fertilizer is combined with deep ploughing, and the depth is 30-40 cm.
2. Fertilizer should be fertilized early after harvest, especially for trees with weaker vigor and more results in the current year. Fertilizer should be applied in time to compensate for nutrient consumption in the tree. Apricot trees are applied with organic-inorganic compound fertilizers immediately after fruit picking. The organic-inorganic compound fertilizers are applied to the plants in an amount of 1 to 3 kg according to the age of the tree and the current year's results, and then watered.
Combine spray spraying with foliar fertilizer and spray 0.3% potassium dihydrogen phosphate and 0.2% urea mixture to increase the nutrient accumulation of the tree and increase the number and quality of flower buds.
From late April to early October, Shiji Fei, based on high-quality farmyard fertilizers, mixed a small amount of compound fertilizer. Generally 5 to 6 years old, the initial result tree is 30 to 50 kilograms per farmer's house manure, 0.3 to 0.5 kilograms of high-nitrogen and high-potassium potassium sulfate compound fertilizer, and 70 to 100 kilograms of high-nitrogen and high-k Potassium sulfate compound fertilizer 0.5 ~ 1.0 kg, water immediately after application.
5. In the first harvest of apricot fruit should be timely irrigation water, so that the soil moisture is most conducive to the growth and development of apricot, this watering can ensure normal flower bud differentiation and shoot growth, aging and maturity. If it is rainy this time, you can not water, but also pay attention to drainage. In places where conditions permit, pour water once before freezing to ensure safe apricot wintering.
2. Diseases and Insect Pest Control Apricot trees are often harmed by pests and diseases after fruit harvesting. They should be sprayed and controlled in time to protect the leaves and increase the nutrient accumulation of the tree according to actual conditions. Can be used 10% imidacloprid 4000 times spray control aphids, with 40% of the water-resistant phosphorothiocite 1500 times or 1000 times liquid Scherin to control spider mites. Spray 2 to 3 times 2000 to 3000 times to kill the pyrethroid, eliminate sweep to prevent the caterpillars and naval caterpillars. From August to October, M-45, thiophanate-methyl, and carbendazim were used to control apricot treatment and bacterial perforation in every 15 days.
