Fruit tree application "magic" technical guidance

1. Prevention measures for root cancer in fruit trees

A. The trunk showed that the secreted resin was grayish-brown after drying, and the epidermis was epiphyseal at the late stage. On the side of the disease, the new leaf was wilting and even died.

B, rhizomes appear as fold-like piles, shaped like mustard.

C. Control methods:

(1) Scrape the skin and apply medicine. Scrape the diseased part first with a knife to expose the formation layer without causing injury. If the formation layer has become blackened, then how much blackening occurs will scrape off much. In the upper part of the lesion, it is 1-2 cm longer to the healthy part, and the healthy part below the lesion is 2-3 cm longer. Then apply the following formula. Gene activator 100 times + "magic square" 6 60 times + 50% disinfectant to escape 30-50 times + "magic square" 10 times, brushing the scraped skin, can be effectively controlled on the trunk in advance.

(2) Treatment of rooty mustardous neoplasms: Disperse the topsoil of the tree discs, expose the roots, remove the neoplastic lesions with a quick knife, and then use pyrimidine peptomycin 500 times (or pentachloronitrobenzene) + ". The Rubik's cube 500 times 500 times seaweed 1000 times liquid and smeared and mixed into the roots, control 3-5 days, then poured once again according to the above concentration of 50%, the water seepage and then sealed soil recovery.

(3) When fertilizing fruit before harvest or in early spring, add 1/3-1/4 of active bio-fertilizer to the total amount of base fertilizer, and the farmyard fertilizer must be fully fermented, and also “magic cube” No. 1 1000 times liquid spray. In the base fertilizer after fermentation, it is of great benefit to improve the rhizosphere soil environment.

(4) Adding “magic cube” No. 1 800 times liquid while pouring root water, control the disease and delay root premature aging.

2. Trunk turbulent glue

In terms of physiology and infestation, this is controlled by infection.

Before each year without flowering, scrape off the flow plastic block and mix thoroughly with 50 % 50 g + 50 % sulfur suspension 250 g + "Magic" No. 6 50 ml cold water 100 - 150 ml. Diseased part. Combined with 70% thiophanate-methyl 1000-fold + "magic square" 6-800-fold + gene-activator 1000-fold + seaweed-fine 1000-fold mixed with whole plant, in the dry season or in the rainy or lightless season, 10-15 days apart 1 time, 2 times.

3, solid root, anti-aging benefits early

In the early freezing season, early and late freezing, and in the case of noonization, first water the "magic square" No. 1 800 times liquid + Shirfu 500 times mixed liquid, 2-5 kg ​​per plant, and then drain water after netting. When sprouting in spring, the mixture is poured into the roots before watering. The formula is 800 times the "magic square" No. 1 + 1000 times seaweed extract + 150 times Schiffuine or potassium dihydrogen phosphate + 800 times more than Baixe. It is conducive to the establishment of a good root environment that can be regulated for years.

4, control of physiological deficiency

In the young fruit development process, such as the encounter more than one week of drought (provided that the base fertilizer in the high phosphorus content before the high partial amount) can be used "magic" 1 600 times liquid + urea 150-300 times + seaweed 400 times to the foliage spray. Interval 3-4 days, once or more than 2 times, can control longitudinal cracking (if cracking fruit has been seen once every 3 days for 3 consecutive times) 10 days after fruit picking, use gene activator 1000 times + "cubes "2 800 times + 600 times seaweed and other suitable foliar fertilizers, spraying to the whole plant, once every 15 days. In other developmental stages, such as pre-flowering, post-flowering, and young-fruiting period, spraying according to this method will avoid the occurrence of deficiency of fruit trees. It can not only improve the quality, insect resistance, disease resistance, but also increase the yield.

5, pest control

(1) Adopt black light trapping and bait trapping for adults. The formula for bait trapping is: 125 grams of white sugar, 125 milliliters of vinegar, 5 grams of crystal trichlorfon (using 100 milliliters of boiling water above 85°C) 5 milliliters of white wine , are dissolved in 1250 ml of water, that is, trapping liquid. Placed in the shallow shrews with sawdust or rice husk as a carrier, placed in the middle of the crown. 3 days to add a killing liquid.

(2) Adding 1000-1500 times of green-crystal azadirachtin to conventional insecticides in normal spraying and fertilizer spraying, especially in the middle and late May to the middle and late of August, can provide antifeedant to pests. Repelling effect, the amount of less and less, and can promote the growth of fruit trees, is a good way to prevent long-Jian.

6. Prevention and control of other diseases

(1) Viral diseases: The branches and leaves are not long, and the leaves are small. They can be used to disinfect and escape 1200 times + "magic cube" No. 2 800 times, spaced once every 5-8 days, or mixed with other pesticides, and the concentration is halved.

(2) Botrytis cinerea: Fruit, flowers, early pods from the top, gray fungal spores. Spray 600 times with Terec 600 times and 600 times with Rubik's Cube 2 in the evening sunlight. Interval 6-8 days, 1-2 times.

(3) fruit, from the fruit surface, ulceration, tasteless: use "magic formula" No. 2 800 times + chloramphenicol 300 times + foliar fertilizer amount, 1 can be effective.

(4) Starscream and thrips were sprayed with 500 times the "magic square" No. 2 with corresponding chemical agents, and sprayed three times at intervals of 3 days (7-9 am, 3-5 pm) during spraying. , Note that the surrounding land, vegetables, and weeds are also sprayed to control the host's secondary hazards.

7, see Tianzhu disease

(1) Fog: There are fogs within 2 hours in the morning. The fog should be sprayed on the afternoon of the next morning with more than 3 hours of fog in the morning. Recipe: "Magic Cube" No. 2 600 times + seaweed extract + 800 times oxygen.

(2) Drought and fierce sun day: spray formula: "magic square" No. 2 800 times + sugar 150 times + 150 times vinegar + 1200 times fledging disinfection.

8, see nutrition

Apples, pears, peaches, apricots, cherries, and plums look 3-7 leaves from the top and 4-8 leaves from the grapes. Look for a gradual gradient of the color. If the heart leaves no gradients When the yellow veins, yellow veins, sharp tips, and brown veins between the yellow veins and flower veins are in sharp contrast, the entire plant is sprayed and sprayed: "magic cube" 800 times 800 times seaweed 600 times or "magic square" 800 800 times Schröffer 300 times, 1 more time interval of 5 days.

9, leaf disease perspective in the morning, root fever observed at noon. Look at the auxiliary tip, petiole angle, and the color of the apical shoot. The dark green color of the petiole is sick, and vice versa. In the morning, if the blades are all the same color, no mottle is disease-free. Otherwise, the disease is sick.

10, field effect

Leave a control (1 strain) in advance and cover it with plastic so that it will not receive any medicine. After 6 days of spraying, the leaf color and upturned nature were observed in the same position, and the effect of disease control was observed. The sign was attached between the diseased leaf and the healthy leaf to see the effect after spraying.
