In the apple orchards, the plants with more fruits are subjected to post-harvest top dressing, watering, and sparse flowering, and the bee is sprayed with a boron fertilizer during flowering. According to the principle of setting trees according to branches, according to the principle of quantification, the work of thinning and fruit thinning should be carried out. Flowering period spraying of high-post or propalin or beautiful fruit dew. Do a good job of grafting the buds and branches to protect, sowing green manure, control of red spider, aphids, leaf curl insects, star caterpillars, gold moth, beetles, powdery mildew, flower rot, mold heart disease. The pear orchard is irrigated once in the flowering period to prevent frost. Artificial pollination, spraying of boron fertilizer, sparse flowering, in early April the inflorescence separation period, sparsely weaker, more inflorescence, leaving the leaves shoots, the inflorescence can be removed when the formation of flower buds. The left inflorescence should be removed from the center of the flower, leaving 2 to 3 flowers. The diseased shoots, diseased shoots, diseased fruits, and diseased leaves were removed. Manually catch pests: Regularly inspect the branches and find the worms as soon as possible, and use the injection needle to inject 50-fold diluted dichlorvos or kill pine. Using a sharp knife to cut the skin to kill the gudgeon, catch the beetle in the evening before and after flowering, and shake off the pear on the branch in the morning to catch and destroy. Prevention of scab, black spot, ring sputum, rust, pear hibiscus, pear borer, two-spotted spider mite, chafer, pear stem bee, and yellowfly. Vineyard 1 is on the shelves: when the grapes are fresh, the branches are soft and they should be put on the shelves as soon as possible. When they are on the shelves, the old vines are tied and the old vines are distributed evenly. The result is best placed at a position over 50 cm above the ground; the branches are tied according to the requirements of the tree. And add trim. 2 new garden colonization: planting seedlings with 25 mg / kg naphthalene acetic acid immersion roots, after planting film, application of available nitrogen fertilizer, irrigation prime water. 3 Soil fertilizer and water management: Green manure, overturning green manure; clear tillage, weeding once again closed herbicide before weeding; to protect the soil temperature and prevent pests, can be a layer of plastic film underground. After the grapes are put on the shelves, topdressing the bud before applying fertilizer, urea or 40-50 kg of diammonium phosphate is applied to 667 square meters of mature gardens and watered after fertilization. Such as spring drought in late April and then irrigation, cultivating after irrigation. 4Pest control: When the Scales of the bud are split and the buds are in a viscous shape, the spray may be sprayed with 3 to 5 degrees lime sulfur and 240 times half Bordeaux mixture (but the two cannot be used together. The interval is more than half a month. ), Prevention of black-pox, felt disease, white rot disease, and spider mites, scale insects and other pests and diseases. The operation must be detailed and the branches and buds should be sprayed with medicine. 5 smear buds: The first time the leaf is budded. The buds that sprouted on old vines, the weak branches that sprouted at the base of the mother twigs, and the buds that sprouted on the surface of the secondary buds except for the ones that were left as renewal were all removed. When young twigs are not covered, the resulting buds on the mother twigs have inflorescences, which can be preserved. Afterwards, different picking treatments are performed. Taoyuan 1 pre-flower dressing: mature tree (peach more than five years) before flowering can be appropriate fertilizer to make up for tree nutrient deficiencies, and quick-acting nitrogen fertilizer (such as urea, agricultural ammonia, etc.) as well, increase the proportion of potash fertilizer (not to mention Chlorine-containing fertilizer was used, and the amount was determined according to the age of the trees and the amount of the results. Top dressing was performed at 0.5 kg/plant. 2 control of pests: before flowering (big bud stage) spray imidacloprid 1500 times + 500 times enzymatic zinc, to control aphids and other pests; scarab serious orchard can be hung more sweet and sour cans, or placed in the park mixed Xin Phosphorus spinach, according to the phenomenon of suspended animation of chafers, in the evening or early morning shake the tree to kill. The specific method is to put a thick plastic film under the tree, shake the tree to shake off the beetle, lift the plastic and pour it into the container to kill. Application of phoxim and kerosene emulsions to prevent and control Giardia infestation by Giardia. 5 to 7 days after flowering, spray 5% Shida Emulsion 1500 times liquid + 50% Wanwenning WP 800 to 1000 times or 70% Mancozeb WP 800 to 1000 times or 80% Dasheng M- 45WP800 times liquid. Control of aphids, leaf roller insects, leaf leaf moth, bacterial perforation and so on. 3 Thinning and thinning fruit: The sparse flowering should be carried out during the period when the flower buds are blooming, the flowers on the sparse flowering tree, the flowers in the lower part of the canopy, and the flowers on both sides of the middle part of the branch and under the back. 4 foliar spray fertilizer: Sand easy to lack of Taoyuan, there shoots top dead and fruit deformities, flowering spray 0.2 ~ 0.3% of borax or boric acid can be solved. After Xiehua, spraying amino acid micro-fertilizer and potassium dihydrogen phosphate 300 times every 15 days, even spraying 3 to 4 times can reduce peach, especially late ripe peach cracking fruit, and can increase production. 5 Summer cut: In the middle and late April, the cut spores and branches of disease and insects shall be wiped off in time, the young shoots of the saplings shall be budded, and the good shoots shall be left to cultivate the resulting branches and the buds on the rootstock shall be completely wiped off. Apricot orchard, cherry orchard, and winter jujube orchard 1 sheet of apricot orchard are prepared to protect the smoked grass from frost. Spraying borax and urea during flowering. Prevention of beetles, almond bees, aphids, apricot weevil, caterpillars, apricot apricots, leaf curlers, etc. 2 The cherry orchard sprays boron fertilizer during flowering. The control of adult hairy beetle, oriental beetle, big gray weevil (young fruit orchard), early defoliation, leaf spot, turtle wax, and leaf lice are used to block the wormhole on the stem and prevent red neck beetles. Young trees spray paclobutrazol. 3 In the early stage of germination of winter jujube garden, 0.3-0.5 Baume degree lime sulfur was sprayed. The black light traps and kills the jujube adult. In the middle and late of the prevention and treatment of jujube, red spider, date stickworm, jujube-like weevil, jujube cockroach and other mosquitoes.
