Cold dew solar terms have quietly passed. In the eyes of peasant friends, cold dew solar terms are not only an important period for autumn harvest, autumn planting, and autumn tube management, but also a key period for fruit tree management. Many fruit trees are the most important time for growth and development before and after the cold dew. The management at this time will directly affect the yield and quality of the fruit tree that year, so how to manage the consequence tree before the cold dew?
1. Citrus
(1) Early-harvest fertilizer should be applied in the middle and late varieties.
(2) Late autumn shoots are erased in mid-late varieties. Very early maturing varieties are thinned and cut in time after harvest, and the fruiting branches are cut short and thick.
(3) Do a good job in the prevention and control of red spiders, rust ticks, whiteflies and other pests. The mountain orchards should do a good job of controlling the fruit-sucking nightworms, and pay attention to the control of ulcer and anthracnose.
(4) Harvest and fertilize early-maturing varieties.
2.Myrica rubra
(1) Yangmeiyuan's deep soil conversion should be carried out according to local conditions. Deep turning depth of 30-40 cm, combined with soil modification, turf and weeds are buried in the soil.
(2) Continue to control the giant moth and disease.
(3) Continue to pay attention to typhoon damage. After the typhoon, cut off the branches promptly, straighten the plants and cultivate the soil in the rhizosphere to restore the tree vigor as soon as possible.
(4) Do a good job in planning and constructing the new development of Yangmeiyuan. The garden should be selected for convenient transportation, deep and fertile soil layers, and slightly acidic or neutral shady slopes or semi-shade slopes (northeast slopes) for planting. Ladder fields with a width of 3-4 meters should be built on gentle slopes, and fish scale pits can be used for steep slopes.
3. 枇æ·
Continue to apply fertilizer before flowering, and make labor arrangements and material preparations for thinning buds, thinning flowers, whitening tree trunks, clearing gardens, and preventing frost.
4.Peach
Late maturing varieties continued to be basal fertilizer. New orchards are ready for construction.
5.Grapes
Focusing on basal fertilizer application, make preparations for the development of new vineyards.
6.Pear
Continue to maintain the maximum leaf area and the center of optimal photosynthetic efficiency, apply topdressing outside the roots, re-apply over-wintering base fertilizer after harvesting, and strengthen pest control work such as army insects. Preventing fallen leaves too early and inducing secondary flowering affects the amount and yield of flowers the following year. Develop winter pruning plans and production plans for the coming year.
The above are the main points of the management of the consequence tree before the cold dew. Farmers should strengthen the management before the cold dew, and timely prevent the impact of the weather changes on the fruit trees. Pay attention to the prevention of fruit tree diseases and insect pests and achieve the goal of high yield and high yield.
