Fruit Tree Spring Management
First, Shi Shi Shi Chun fertilizer application of good spring fertilizer is conducive to promoting the development of spring shoots, improve the quality of flowers, lay the foundation for this year's fruit production and stable production. Peach, grape, pear, apricot, navel orange and other fruit trees in the spring fertilizer to fruit trees special fertilizer or special tree species active strong fertilizer can be, and then with the cleansing water 1000-2000 pounds applied to the tree dripping as the boundary, and then cover the fertilization nest. The tree manure is actually a steady fruit fertilizer. Phosphate fertilizers should be used as much as possible to minimize the application of nitrogen fertilizer to promote fruit enlargement and overcome the contradiction of the fruit. The grape result tree should pay attention to nitrogen control before flowering and control the growth of the tree. Increase the use of special fertilizer for grapes to promote sprouting, larvae, and flowering. The purpose of this fertilization is to increase the quality of flowers and to supplement the consumption of nutrients. In order to ensure the normal growth and development of all kinds of fruit trees, such as flowering, shoots, and fruit growth and development, timely irrigation should be performed to ensure the water requirement of the fruit trees. The degree of irrigation can be performed according to the drought conditions, and it can also be used for the application of spring fertilizer. get on. Sapling management should be applied sparingly and thinly to fertilize water. Once every half a month of defecation water, add 1 to 2 urea (2 to 4 strains). When the shoots shoot up and shoot out, the amount of foliage is already available, and less nitrogen should be applied. Phosphorus and potassium were applied to supplement the branch buds and early results were achieved. Second, pest and disease prevention spring As the temperature rises, a variety of pests and diseases will gradually pick up, this time should seize the favorable opportunity for chemical control. 1. Peach: Time: The buds are green and the top of the flower buds is red. Methods: The main treatment was leaf shriveling, and the crown spray was applied with Baume 0.8-1.5 degree lime sulfur or 500 times fungicides. Leafminer control: Occurs in late March and can be controlled by Kangfudu 3000 times liquid. 2, grapes: to control gray mold, black pox, anthrax, brown spot mainly. Before germination, it was treated with Baume 1-2 degrees lime sulfur or 800 times carbendazim. 3, pears: to control black spot disease, rust, pear small borer heartworm-based. (1) Control with Fortune 4000 to 6000 times solution. (2) The powder spray can be sprayed with 1000 times of powder rust. (3) Use the enemy to kill or 1000 to 1500 times the liquid to spray the crown, 4, and (1) the locust control; Each time the shoots are harmful young leaves, suck the leaf juice, make the leaves shrink Anti-volume, prevention and control of drugs have a net, Mobilang 1500 ~ 2000 times liquid for prevention and treatment. (2) Yellow caterpillars and navy caterpillars. This larva eats young leaves with larvae. The larvae are nicked. Large larvae directly feed on the old leaves and can be killed by hand. They can also be controlled by chemicals, and can be used to control 1600-2000 times liquids. . 5, navel orange: mainly red, yellow spider prevention and control, available Nisuolang 1000-1500 times control. Third, Baohuabao fruit technical points l, peaches: (1), before or after flower can be used 300 to 500 times the amount of fruit Feng Ling Feng or yield-producing fruit spray, this can increase the nutrient level of the tree, achieve stable fruit effect . (2) Artificial pollination (3), using pollen solution, bee sugar (0.2 kg) and pollen (2 g) plus water (2 kg). (4) Spraying 0. s% of borax (peach, pear). (5) Eliminate the buds and the buds. (6), fruit thinning, 2~3 long fruit sticks, 2 kg fruit fruit, 1 short fruit stick. 2. Grapes: (1) Wiping buds: When the grape buds are drawn to 3 to 5 inches in length, the weak buds and shaded buds are wiped off, and 5000 to 5500 buds are left in the mu. (2) Topping: Generally, 6-8 leaves above the ear should be picked up. Note that the diameter of the leaf to be picked must be about 8cm. (3) Spike: Remove the spike and remove the spike tip. 3. Pears: (1) Open branch angle (2) Artificial pollination (3) Use pollen solution to increase fruit set rate (4) Thinning fruit: After the first physiological fruit drop, leave 8000 to 10,000 fruits. 4, navel orange: (1) before flowering cut, cut off the leaves without flowers, sticks, weak branches, and according to 3 draw 1,5 pumping 2 shoots to dredging. (2) use ba-ga to preserve fruit. a, coated fruit type: 1 litres of water early l pounds, after the young fruit flower fruit fruit or fruit b, spray cloth type: 1 (10 ml) watered 20 kg, flower Xie 70 ~ 80% spray once, Xie spend 20 days after spraying again. c, to prevent umbilical yellow fruit drop: with fows umbilical yellow inhibitor, in the navel orange young fruit by 1cm, 1 (10 ml) watered 0.6 kg plus 0.3 ml enemy killed, plus a small amount of fungicide (carbendazim ) Tu fruit navel. d, fruit thinning: 8000-lo000 acres of fruit.
