Cultivation of greenhouse ripe peaches

The cultivation of early ripe peaches in greenhouse is one of the main methods for the cultivation of fruit trees in China in recent years, and can obtain high economic benefits. Solar greenhouses or plastic greenhouses can be cultivated. The main management measures are as follows:

The timely addition of membranes is a key technology to ensure the early maturing, high yield and high quality of greenhouse peach trees. The film must be applied after the peach dormancy period. In order to make early-mature peaches available in the morning market, the peach seedlings will be planted in the greenhouse in late November, and the grass will not be covered with grasshoppers. The natural dormancy period ended in late December and the greenhouse began to heat up. In the first half of January, decals were applied, and at the same time, mulching was used to cover the ground and the contradiction of physiological incompatibility between the ground and the underground was eliminated.

The peach tree began to sprout when the room temperature was adjusted and the average temperature on the day of light reached 7-8Â°C. Germination period at room temperature during the day to maintain 20 ~ 30 Â°C, the night is not at the end of 5 Â°C, the most suitable flowering time at room temperature is 12 ~ 14 Â°C, fruit setting during the daytime temperature is appropriate to 20 ~ 25 Â°C. Should use a good light-transmitting non-dropping film, timely removal of grasshoppers during the day, full illumination.

The scientific management of water, peach and peach trees was lifted once after dormancy, once before flowering, and once after flowering. Drip irrigation was used lastly. After the irrigation, open the air outlet at noon on a sunny day to remove moisture. After flowering and during the period of fruit enlargement, 20 kg of diammonium phosphate and 15 kg of potassium sulfate are applied separately after each fruit planted with acre, perforated and fertilized, and then watered and covered. Foliar application of 0.2% urea plus 0.2% potassium dihydrogen phosphate solution was applied once every 15 days from fruit setting to fruit ripening. Do not water it 20 days before peach picking to prevent fruit drop and cracking.

Pruning in greenhouses Peach trees are dwarfed and can be planted in cups. In early December, sparsely ill, injured branches or short cuts, long fruit branches retain 6-7 buds. After flowering and fruiting, the branches are cut without flowers and with little fruit. After harvesting the fruit, the branches and branches of the pests are cut and the branches are renewed.

Prevention and control of pests and pests are mainly locusts, red spiders, borerworms, etc. The control of aphids is to spray 20% sprayed or killed 2.5% enemies to kill 1500 times liquid in the germination period of peach trees; Can be sprayed with 10% bifenthrin EC 3000--4000 times solution; use 25% of deltamethrin or fenvalerate 25% liquid control.
