One, buckle shed warming. After the peach tree meets its cooling capacity, it can be warmed to relieve sleep. In the area south of 34 degrees north latitude, due to falling leaves, it is also late to enter the dormancy period. The species requiring 600 hours of cold can be warmed up in the first half of January. In the area north of 36 degrees north latitude, advance sheds can be used to cover the sheds during the day and exposing them at night to promote early dormancy. After the cold, it was revealed that the temperature was rising. Second, fertilize water, cover the film. Before warming up, the entire greenhouse was filled with water once. If the application of autumn basal deficiencies or weak trees, can be applied compound fertilizer 0.2-0.5 kg / strain; need to be paclobutazole control, can be applied 0.5-1 g / square meter (15% content), and then irrigated with water. When the topsoil is not sticky, the whole garden film covers. The mulching film is conducive to maintaining the ground temperature, especially after irrigating, and the ground temperature rises faster.
The conditional laying of drip irrigation pipe, and later to the fruit ripening period without flood irrigation, drip irrigation, both water-saving and conducive to control the humidity inside the greenhouse.
Intercropping strawberries. The age of the tree is 1 year old or 2-3 years old, and there is space after the thinning between the rows. It can be interspersed with strawberries. Strawberries need to be planted in the middle or late August, when the temperature rises, they will be covered with plastic film. After the plastic film was flattened, the film was punctured to expose the strawberry seedlings, and then the soil was sealed tightly.
Fourth, adjust the temperature. Temperature control period is mainly germination, the temperature is maintained at about 8-15 °C, the lowest 0-5 °C, the highest 25-28 °C.
In the early days of the solar greenhouse (about 1 week), half of the grasshoppers are pulled up first, and a small amount of light penetrates through them to gradually increase the temperature, so that the peach trees can move slowly, which is beneficial to the balanced metabolism of various hormones and nutrients. Open all the grasshoppers after 1 week and see the light fully. The room temperature is maintained at 10-25°C during the day, 5°C at night, and 15-20°C at the floor temperature. The budding temperature is preferably 5-28°C. It is usually open at 8:00 am and released at 16:00 pm.
Plastic greenhouses should be well insulated at this time, because in the middle and late January, the temperature is very low, easy to snowfall, sprouting long after the cold resistance is extremely low, the temperature below 0 °C will cause cold damage. When conditions are cold, conditional heating and hot air furnaces are used to assist in heating.
Fifth, control the humidity. The relative humidity of the air from the garret to the bud should be kept at about 80%, and it should be controlled at 50%-60% at the flowering stage.
Six, prevention and treatment of pests. Sprouting the 3-5 degree lime sulfur mixture at the beginning of germination can prevent disease and kill winter spiders. Attention should be paid to careful spraying. Lime-sulfur mixture is made of quicklime and sulfur powder. It is made up of reddish-brown liquid added with hydrazine. The active ingredient is calcium polysulfide, which is strongly alkaline and soluble in water. It has strong contact and killing effect on leeches.
The lime-sulfur mixture must be selected from high-quality quicklime, and the lime already used should not be used. The ratio of lime, sulfur and water is 1:2:10.
The preparation method is as follows: first put the quick lime in an iron pot, add a small amount of water and heating after adding a small amount of water, and at the same time, use a small amount of warm water to adjust the sulfur powder into a paste for use. When the water in the pot is almost boiling, pour the sulfur paste into the lime liquor slowly along the side of the pan, stir it down, and record the water level line. The fire was heated and boiled for 40-60 minutes. When the liquid turned to reddish-brown, the fire ceased.
It should be noted that during the boiling process, proper stirring should be performed and hot water be used to make up for the evaporated water. After cooling, the residue is filtered off, and a red-brown lime sulfur stock solution is obtained. Prior to use, the concentration of the stock solution was measured using a Baume pycnometer, and then diluted with water to a desired concentration as needed.
