Proom cultivation techniques

Second, the greenhouse requirements Peach greenhouses can be used to cultivate greenhouses or plastic greenhouses, generally span 7 meters -8 meters, 50 meters -80 meters long, top 2.5 meters -3 meters high, spacing 1 meters x 1 meters. Sunlight greenhouses take east-west directions, and plastic greenhouses take north-south directions. They are planted in north-south rows and are planted in double rows or three rows. The distance between the two rows is between 1 and 1.5 meters. Solar greenhouses should be applied north of 33 degrees north latitude.

Third, the main cultivation measures

1. The dwarf seedlings will be planted in peach pots with a diameter of 40 cm in the spring after the anvil is cut. The soil, sand and horse manure are added to the pots to prepare nutritious soil and then exposed to the ground. After the seedlings have survived, cover the mulch and remove the sprouts on the rootstock. When the buds grow to 10 cm to 12 cm, they pick their hearts and trigger the shoots. Select three azimuths with an azimuth angle of about 120 degrees as the primary branch, and when it grows to 15 centimeters to 20 centimeters, perform the second picking. From the secondary shoots germinating at the front end of the primary branch, two symmetric growth shoots were selected as the secondary main shoots. When they reached 20 cm or more, the third picking was performed. Two secondary buds sprouted from the front of the secondary main branch and two were selected as the tertiary branch, and finally a circular tree with 12 tertiary branches was formed. Each time the pincers are picked and sent out as the main shoot, the rest of the visual space is selected and left. In the initial stage of growth, irrigation is performed once every 10 days, and the soil is loosened in time. Before the soil is loosened, 50 grams of chicken manure is applied to each pot, and a total of 2 treatments are applied - 3 times. In late November, peach seedlings were transplanted into the greenhouse and 5,000 kg of fertilizer was applied per mu before transplanting.

2. Results Tree pruning In early December, the diseased, injured or short branches were removed, the long fruit branches retained 6-7 flower buds, and the short fruit branches retained 1-2 flower buds. The fruit-like branches of the bouquet are either lightly cut or not cut, and the overlapping branches are pulled or removed. The standing branches are flattened or short-cut, and the distance between the branches is maintained at about 10 cm. After flowering and fruiting, cut no flowers, little fruit, and fruiting branches. After picking fruit (in early May), the greenhouse plastic film was peeled off, pests and branches were cut off, and the long branch was cut off. From late July to early August, the inner limbs are excessively flattened or evacuated, and the upper and lower branches are short-cut or side-pulled. Make the tree windy. During this period, pruning focuses on thinning, so that the internal spasm, the external sparse, back sparse, back sparse sparse, sparsely crowded, cross, weak, leafless, diseased branches, pull down or remove extension branches, competition branches .

3. Plum and water management Peach trees are discharged once they are dormant and once before flowering, they are irrigated once. It is best to use drip irrigation. After the irrigation, open the air outlet at noon on a sunny day to remove moisture. In the pre-flower, post-flower, fruit expansion period, after each fruiting acre harvested 20 kg of ammonium dihydrogen phosphate, plus 15 kg to 20 kg of potassium sulfate, fertilization by iron brazing, irrigation, soil after application. From the fruit set to the fruit ripening period, spray the 0.2% urea plus 0.2% potassium dihydrogen phosphate solution once every 7 days.

4. Artificial pollination and sparse fruit blossom 1 day - 2 days after flowering, at the 9 o'clock in the morning, use a feather duster to roll on the tree of the pollination variety, then roll on the tree of the main cultivar, and pollinate 2 times - 3 times in the whole flowering period. During the period to eliminate dense flowers. After the natural physiological fruit drop, when the fruit grows to the peanut size, the fruit is thinned, sparse and produce fruit, small fruit, malformed fruit, and yellowish shrivel. The fruit quantity is determined according to age, tree vigor, etc. Small fruit type 5 cm-7 cm to stay 1 fruit, big fruit type 8 cm-12 cm to stay 1 fruit, sunny face, big tree, strong branch appropriate multiple fruit .

5. Pests and diseases Prevention and treatment of premature peaches in the greenhouse are rarely diseases. It was found that the flow phenomenon can be sprayed with a 70% thiophanate-methyl wettable powder 1000 times solution. Insect pests include aphids, hawthorn, and red spider, etc. The key measure for the prevention and control of peach aphid is to spray 20% of extinction at the early stage of germination of peach trees; Hawthorn red spider attacks trees on peach trees and harms the trees and can spray 10% bifenthrin. Emulsion EC (Uranus) 3000-4000 times liquid prevention.

6. After the dormancy and temperature control shelters were lifted, the peach trees in the greenhouse ended their dormancy period in mid-late December and the greenhouse began to heat up. Detain the shed film, close the air hole and open the grasshopper during the day to heat up. When the average temperature reached 7°C-8°C, the peaches began to sprout, and they bloomed at 10°C. The average daily temperature during flowering was controlled at 12°C-14°C. In addition to the good temperature during flowering, but also ventilation and ventilation, open the vent at 7-8 in the morning, ventilation for more than half an hour. During the fruit growth period, the daytime temperature should be controlled between 20°C and 25°C.
