Spring apple tree management technology points!

The management of apple trees in spring should focus on scientific fertilization, guarantee of fruit setting and control of diseases and insects, so as to ensure the high yield of the orchard. Fruit pollination pollen manufacturers have arranged specific technical points.
1. Scientific fertilization
Now comes the spring bud germinating pear weeding period, when weeds is broken. In order to prevent the competition between weeds and fruit trees, nutrients should be removed before fertilization. Weeding according to the growth law of pear roots is conducive to the growth of new roots. Weeding can be done by weeding or chemical weeding.
Fertilize the grass after the tree is fertilized. The best young Qin Shi and Bo Shi, with the maturity of animal manure and urea, dig into the hole after the soil; the result tree at the end of February the germination of fertilizer, mid March to mid April application of spikelet promoting fertilizer, applying fertilizer during fruit development. Every time with the maturity of animal manure, plus 0.5 kg urea per pick; early results 4 strains of trees; in the full fruit period 2 tree strains, 1 strains of tree application, canopy drip at the hole or furrow fertilization timely complex soil. In case of drought, but also ensure timely watering, germination, sprouting, flowering and young fruit, wet to clean up the drains to prevent root water expansion.
Two, guarantee the rate of fruit sitting
The best time of flower bud thinning flower Lulei prior to flowering, the sooner the better. Interval 25 to 30 cm, leave a inflorescence, after inflorescence separation, each inflorescence with 3 flowers on the base, try to select the inflorescence on both sides, leaving the inflorescence quantity slightly larger than the remaining fruit.
In flower thinning, fruit quantity according to the varieties, ages and vigor and. Each inflorescence was sparsely into fruit, fruit shape, length of fruit stalk, no damage and pest of fruit, try to choose the left base of the 2 and 3 order fruit. As a result, the middle and lower part of the branch remained more, and the shoot tip remained less; the side fruit remained more and the lower fruit remained less.
Pollination of apple trees with scientific pollination directly affects pear malformation and yield. Pollination and artificial pollination can be adopted for pollination. In the 5 to 7 days before flowering, bees are pollinated, and the bees are placed in apple orchard. Especially in close planting pear orchard, the best effect is that artificial pollination should be done early, and pollination flowers should be collected as early as possible, then pollen can be removed, and a small amount of pollen should be dipped with brush or paper stick. You can start early flowering pollination, each inflorescence point base of the 1 - 2 flower best, the flowering at 2 - 3 times.
Three. Prevention and control of diseases and insects
Pest control of apple tree and widespread occurrence of severe diseases pests have scab, rust and rot, rot, black spot, they will lead to the growth of apple trees, the breakdown delay, production decline, excellent fruit rate is low.
The following specific prevention measures: germination, spray 2 - 3 degrees LSSS once, can prevent overwintering of apple trees, scale insects and other pests by March; flower bud crack period, 50% carbendazim spraying 500 times liquid, disease prevention and treatment of solid food such as apple tree insect pest and bud anthophagy black star, black spot, spot; the end of the mid March, with 65% zineb 500 times liquid spray; in early April, fruit period with bayleton plus 500 times liquid avermectin 2000 times liquid spray, the control of apple tree rust.
