Pear spring management technology

Pear spring management to scientific fertilization, pest control, protection setting and so on, to ensure high yield orchard. The specific technical points include:
Now comes the spring bud germinating pear weeding period, when weeds is broken. In order to prevent weeds and trees to compete for nutrients, weeding fertilizing, weeding according to the growth rule in favor of the new pear root, root growth, weed control by artificial weeding and chemical weeding.
Press the tree to fertilize and weed. 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.
The best time of flower bud thinning flower Lulei prior to flowering, the sooner the better. Interval 25 - 30 cm to leave a inflorescence, inflorescence separation, each inflorescence to stay at the base of the 3 flowers, as far as possible to choose the left side of the inflorescence, leaving a little more than the amount of inflorescence.
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. The branches in the lower part of leave, leaving less side branches; fruit to stay back, leaving less fruit.
Pear pollination can affect pear pollination scientific malformation rate and yield directly, can take on pollination bee pollination and artificial pollination.
Bee pollination, generally in the 5 - 7 days before flowering, the colony in the opera, especially the best Planting Orchard effect; artificial pollination, early acquisition of pollinated flowers, then remove the pollen, take a small amount of pollen points granted with brush or wand dip. You can start early flowering pollination, each inflorescence point base of the 1 - 2 flower best, the flowering at 2 - 3 times.
The widespread occurrence of pests and diseases and insect pests of pear severe pests have scab, rust and rot, rot, black spot, they will lead to weak growth, the delay, pear production decline, excellent fruit rate is low.
The following specific prevention measures: germination, spray 2 - 3 degrees LSSS once, can prevent the winter pear Psylla, scale insects and other pests; March flower bud splitting period, 50% carbendazim spraying 500 times liquid, disease prevention and treatment of solid worms, tiger pear pear bud - eating pests and black star, anthophagy black and brown spots; the end of the mid March, with 65% zineb 500 times liquid spray, prevention and cure of bee flower pear fruit rot; in early April, fruit period with bayleton plus 500 times liquid avermectin 2000 times liquid spray, control of Pear Rust, pear Psylla, pear aphid, pear tiger etc..
