Pruning of pruned early-maturing varieties of walnuts in the sapling stage is dominated by cultivating trees to prevent premature formation of small old trees, and at the same time opening the angles, the branches of the branches should be appropriately shortened to promote their growth and make them grow as soon as possible. Forming; For the early fruits of the full fruit period, the walnut should be moderately shortened and retracted to maintain the growth potential of the branches and the resulting sticks and extend the resulting lifespan. Late maturing cultivars are more prosperous during the sapling period, and the results of the terminal buds are the main factors. Therefore, in the sapling stage, the long and open angles should be lightly cut to increase the proportion of short and middle branches, and promote the early results of multiple flowering; During the fruit period, the pruning of mid-late maturing varieties should pay attention to opening angles, removing dense auxiliary supporting branches, and improving the ventilation and light transmission conditions of the tree body. For many consecutive years, the result branches should be moderately retracted to maintain its strong growth potential. . After being pruned, it was promptly cleaned up, rubbed wounds and anti-corrosion films were applied at the big wounds to protect the healing tissue and prevent infection. Fertilizer management After the soil is thawed, the tree body is poured with germinating water before germination to supplement the loss of moisture in winter and promote shoot growth and flower bud differentiation. At this time, watering can also reduce ground temperature delay flowering period and avoid late frost damage. Spring fertilization is mainly based on topdressing available nitrogen (urea). Pest Control 1. Clean up the litter and weeds in the park and burn them in a concentrated manner. 2. In the early spring, the whole tree is sprayed with 1000 times liquid to protect the tree, preventing frost and overwintering pathogens. 3. To strengthen the prevention of rot and ulcer disease. If you find that there are dangerous symptoms, use a blade to gently scribe on the diseased skin (vibration can make the spores sporadically fly), and use a brush to apply the general tree of the tree, so that the diseased skin can begin to dry after 3 days and the dead spores can be stained in 30 days. The diseased skin began to fall off. Erythritol For Juice,Organic Erythritol For Juice,Liquid Erythritol,Puresweet Erythritol Ningxia Eppen Biotec CO.,LTD , https://www.nxeppen.com
Walnut tree spring pipe grasp three points
The management of walnut trees in the spring is mainly for fertilizer and water management. At the same time, spring pruning and sprout water irrigation are needed. The control of pests and diseases will ensure the high yield of walnuts. How to manage the walnuts in the spring? Recently, the reporter interviewed the researcher of the Forestry College of Northwest Agriculture and Forestry University. Lu Zhoumin.
