How much fruit do walnut trees bear?
How do walnut trees bear more fruit? What are the ways to make walnut trees bear more fruit? Also ask experienced netizens to help introduce that walnuts are becoming more and more popular with the improvement of living standards. at the same time, walnuts are also the most new products to play with, but the low fruit setting rate of walnuts is the biggest headache for fruit growers. Three methods that can improve the fruit setting rate of walnut trees are sorted out for this kind of ground net, which are listed below for netizens' reference. Method 1. Improve from the method of fertilization: it is suitable to apply farm manure and nitrogen, phosphorus and potassium compound fertilizer. Fertilize twice a year, the principle of fertilization: should be deep rather than shallow, far should not be near, appropriate amount is not excessive. The amount of fertilizer applied each time can be determined according to the quality of the soil and the tree. High nitrogen compound fertilizer was applied before the result, and potassium sulfate compound fertilizer was applied after the result. Method 2. Improve the management of flowering and fruit stage: 1. Artificial assisted pollination: artificial assisted pollination can increase the fruit setting rate of walnut by 10% to 30%. When the female flower stigma is in the shape of "inverted eight" and the stigma secretes a large amount of mucus, artificial pollination is carried out at 9: 10 am, and the effect is ideal. 2. the method of eliminating male flowers: the development of male and female flowers will consume a lot of nutrition and water stored in the tree, especially when the male inflorescence grows rapidly and the female flowers bloom in large numbers, the water in the tree will become the limiting factor for the growth and development of female flowers. Removing too many male flowers can reduce the consumption of nutrients and water in the tree, and supply more nutrition and water to the development of female flowers, flowering and fruit setting, so as to improve the yield and quality, and benefit the growth of new shoots and enhance the tree potential. It is appropriate to remove male flowers early, and the earlier the yield increase, the more obvious. The thinning effect of male flower bud is better from dormant period to expansion stage, but it is worse when male inflorescence is obviously elongated and then thinned. The number of male flowers should be removed according to the number of male flower buds and the ratio of mixed buds to female flower buds. The suitable ratio of male to female after thinning male flowers is 30 ∶ 1 to 60 ∶ 1. For plants with more mixed buds and fewer or fewer male flower buds, there should be less or no male flowers. The method of thinning male flowers: combined with pruning with hooked poles, pull down the branches and break off male flowers by hand. Method 3: improve it by pruning and spraying: 1. In June, use a blade to skin the trunk of the tree, draw two vertical roads with a trunk diameter of 5 cm, and handle the trunk diameter of more than 5 cm as appropriate, and the peeling place should be more than 30 cm away from the ground. in order to avoid the soil splashed after the rain to pollute the wound, but not ring peeling. 2. 200 × 300 times of paclobutrazol was sprayed every 10 days from the end of June to the beginning of July for 2 times.
