Zhang Zongqin, associate professor of the College of Forestry at Northwest A&F University, reminded fruit growers that the management of the orchard after grape picking is very important, and timely management of fertilization and pest control should be done to lay the foundation for high and stable production in the coming year.
Clear the garden in time, prevent diseases and insect pests and remove the weeds in the garden, collect the litter and leaves of the orchard and the pruned branches and leaves, and the diseased fruit, diseased ears, diseased leaves and diseased branches discarded in the orchard after fruit picking. Buried deep outside or burned to eliminate the source of disease and insects. In addition, this year the grapes are affected by downy mildew, powdery mildew, white rot and brown spots. Therefore, after the grape fruit is picked, it can be sprayed alternately with 500 times liquid of 50% Kejunte WP, 500 times liquid of 65% Zinc WP, and 1000 times liquid of 70% Thiophanate-Methyl WP. Spray once every ten days.
Controlling the growth of branches and vines will consume a lot of nutrients in the tree body. Measures should be taken to control its growth, such as topping and erasing the secondary shoots, so as to reduce the ineffective consumption of nutrients, and promote the main vines and the retained secondary shoots to be thick, and the buds are full and full . It is also possible to spray 0.05% Bijiu solution to inhibit the growth. At the same time, the branches and vines should be pruned reasonably. The thick branches should be kept more, and the thin branches should be kept less.
Spray the post-harvest fertilizer in time â‘ After the grapes are harvested, spray the foliage fertilizer in time to restore the tree vigor. Spray a mixture of 0.2% urea, 0.1% magnesium sulfate and 0.2% potassium dihydrogen phosphate every ten days or so. Spray three times. â‘¡Reapply base fertilizer. Before the grape leaves fall, the base fertilizer should be reapplied, and the soil manure, circle manure, compost, etc. should be used per acre, and the decomposed human and livestock manure, nitrogen, phosphorus and potassium compound fertilizer, and potassium dihydrogen phosphate should be used.
Timely loosen the soil, prevent waterlogging and drought prevention due to picking management, the soil is easy to be solidified, and the soil should be loosened by cultivating immediately after picking the fruit. Deep plowing and loosening the soil should be carried out from September to October. Deep plowing can be combined with fertilization. When there is a lot of rain, the ditch should be cleared and drained in time. In case of autumn drought, timely irrigation should be carried out to maintain suitable soil moisture. In the autumn orchard, weeds grow and the soil has poor air permeability. Therefore, after picking the fruit, weeding and deep ploughing are carried out in time, which is conducive to the loosening of the soil in the orchard, water and fertilizer retention, and the growth of new roots and shoots.
Reduce damage. After harvesting grapes, some fruit farmers cut off a large number of secondary shoots and old leaves, which not only affects the maturity of the branches in the year, but also forces the winter buds, which seriously affects the growth and results of the plants in the next year. Generally, they do not pick leaves and remove fewer shoots after harvest. Keep strong foliage. At the same time, prevent mechanical damage to branches and leaves during field operations, and ensure that branches and vines mature normally.
