The time of cultivating and weeding is at a time when the spring buds of pear trees are sprouting and when weeds are broken. In order to prevent weeds and fruit trees from competing for nutrients, weeding and weeding should be carried out before fertilizing. Weeding based on the growth law of pear roots is conducive to the growth of new roots. Weeding can be done manually or with weeds.
After fertilizing and weeding trees, fertilize. Saplings are best used for grounds and thin, with decomposing human dung, urea, etc., digging points into the soil after the application; the results of the tree in the end of February to promote germination bud fertilizer, in mid-March to promote flowering fertilizer, in mid-April to develop fruit fertilizer. Each time the decomposed human animal dung is used, 0.5 pounds of urea is added for each pick; 4 trees are planted in the initial result; 2 trees are applied in the full fruit period, 1 tree is applied in the big tree, and the crown can be applied at the drip point or in the ditch. . In case of spring drought, watering should be done in time to ensure that buds, shoots, blossoms, and young fruit inflate. Rainy days should be cleared of drains to prevent water swelling in the roots.
Sparse and thinning fruit sparse flowering time is best carried out from flower bud buds to flowering, the sooner the better. An interval of 25-30 cm left an inflorescence. After the inflorescence is separated, three flowers are left at each base of the inflorescence. The inflorescences on both sides are left as far as possible. The amount of left inflorescence may be slightly larger than the amount of fruit left.
Thinning of fruit is carried out after flowering. The amount of fruit remaining depends on the species, age, and tree vigor. Each inflorescence is sparsely single fruit, leaving fruit shape, fruit stalk length, no damage and pest and disease, as far as possible to choose to leave the base of the 2, 3 order fruit. The result is that the lower part of the branch stays more and the branch shoots stay less; the lateral fruit stays more and the lower fruit stays less.
Scientific pollination pear tree pollination directly affects the pear deformity rate and yield, pollination can be taken pollination and artificial pollination.
Put bee pollination, generally in the 5-7 days before flowering, the bees are placed in the pear garden, especially the best planting pear garden; artificial pollination, pollinating flowers should be collected early, and then remove the pollen, with a brush or paper stick A small amount of pollen awarded. The pollination can be started at the beginning of flowering. The 1-2 at the base of each inflorescence is the best, and the whole flowering period is 2-3 times.
Pest control Pests commonly occurring and severely hazardous are black spot, rust, ringworm, rot, black spot, etc., which can lead to poor growth of pears, delayed results, reduced yields, and low yields. .
The specific prevention and control measures are as follows: Before the sprouting of fruit trees, spray 2-3 degrees lime sulfur once, which can prevent winter diseases such as pear wood worms, scale insects, etc.; March flower buds open period, spray with 50% carbendazim 500 times, control Pear-bearing insects such as pears, pears, etc., and diseases such as black stars, black spots, brown spots, etc.; at the end of mid-March, spraying 65% of zein-zinc 500 times to prevent and control pear plague and flower rot; 4 In early young fruit period, it is sprayed with 500 times solution of rust and 200 times solution of insect pests to prevent pear rust, pear hibiscus, pear locust, and pear.
