One quick topdressing fertilizer. Fruit buds after cold body,

    shoot, flower and young fruit in varying degrees of damage, tree vigor is weak, should be available as soon as topdressing fertilizer to promote tree vigor recovery germination and shoot again. may be outside the canopy drip line of thin urea,

    nitric acid available potassium and other fertilizers, and composting livestock manure and other farmyard manure or slurry manure, supplementary tree nutrition, fruit cells to improve concentration, enhance tree drought resistance and

    disease resistance. may also be timely spraying fertilizer, leaves and branches to enhance photosynthesis, the growth of multi-nutrient manufactured for fruit trees. Second, the root management. orchards shallow Row crop cultivators timely manner, if water or high water table, to the drainage ditch, to clear the air permeability of soil to root, root in order to facilitate robust growth. Third, flower and fruit processing. re-germination of grape branches, with

    inflorescence to all the reservations, no inflorescence after

    topping in germination, and promote its secondary results. timely removal of cold young fruit, reduce nutrient consumption, even if some child Browning will still be swollen after the cold fruit maturity, but no longer value of the goods shall be promptly removed [4]. on the orchard by frost or plant, an inflorescence to change the annual leave one fruit to stay 2 to 3 results, and strive to maintain the normal production tree. peaches and other fruit trees should also young fruit bagging insulation and reduce frost damage

    effect. Fourth, pollination. Flowering case of low temperature, bees and other pollinating insects become less active, can be sprayed de Copp 6 000 times, and make 1 or 2 times artificial pollination, protecting flowers and fruits.

    Fifth, to improve fruit set. spraying days of 2116 +0.5% +0.2% sucrose and 0.3% borax, to reduce damage, improve fruit set. also in fruit set to fruit ripening after 20 d prior to spray 3 to 4 times 400 times dihydrogen phosphate, in order to improve fruit set, increased single grain weight. part of the axillary buds of fruit trees can also use the results to make up part of the production. 4 References [1] Cao Zhong Seoul.
