The cultivating loose soil is usually carried out after irrigation and rain; after each irrigation, the cultivator loosens the soil. On the one hand, water can be stored to prevent soil compaction, and on the other hand, weeds can be eliminated; the number of rains increases after entering the rainy season. The grass grows faster, and it should be done several times more properly with a depth of about 5 cm to prevent damage to the rough roots.
During the intercropping of young trees in the orchard, they can be used as economic crops between the rows. Crops suitable for intercropping should be short and short, have a short growth period, and should absorb less water and nutrients. They need a lot of time for water and fruit to stagger, shallow roots, and fewer pests and diseases. Cherry does not have the same pests or diseases, or it cannot be the middle host of the major pests and diseases of cherries; beans, melons, medicinal plants, and green manures are all good, and wheat, corn, sweet potatoes, etc. should not be intercropped; The intercropping time depends on the planting density and the growth of the tree, and it does not affect the growth of the tree. It is generally 1 to 2 years.
The turning of the soil should be carried out after the autumn basal fertility or in combination with the autumn basal fertilization; the turning is done with a depth of about 15 centimeters, and the trunk should be planed to be slightly shallow so as not to damage the large roots; and the flat ground can be used to make the inner surface of the tree crown. Slightly high to prevent the rainy season from accumulating.
When the orchard grows grass and does not cover or intercropping with cash crops, the orchard can grow grass, save labor and time, increase soil organic matter content, prevent water and soil loss, regulate ground temperature, and reduce frost damage and sunburn; Shallow-rooted, low-dry grasses, leguminous or green manures such as clover and alfalfa are best; in the growing season of grass every year, attention should be paid to the addition of chemical fertilizers to prevent grasses from competing with big cherry trees; in summer, grass grows to 20-30. When the centimeter is high, mowing the grass timely and eradicating the high stalk grass between the rows.
Maintenance of terraces For Cherry Blossoms on hilly terraces, the maintenance of a terraced field is usually performed every year in conjunction with the autumn and winter planer or it can be carried out in the rainy season; the mantle is to be repaired and the soil is reinforced; the bamboo trenches, silt pits and reservoirs are cleaned. Sludge, broken grass, rotten leaves, etc., and turn these sediments to the ground.
Covering the film must use different types of plastic film according to different purposes; if the colorless and transparent film is the best for maintaining soil moisture and increasing temperature, the black plastic film has good effect of heat preservation, heat preservation and weed control, and the silver reflective film has heat insulation and strong Reflect the role of sunlight; to be covered before the fruit is about to be colored, in order to increase the internal light intensity of the crown, improve the quality of the fruit.
When the mulching film is covered, it should be noted that: 1 After watering, the water in the ground must be soaked. After cultivating the ripping soil, the mulch film can be covered. Otherwise, the moisture content in the soil will be too large. After the film is covered, the moisture will not easily dissipate, and the air permeability will be reduced. Root rot; 2 mulching film can not be too wide, the general saplings cover only 60 to 80 cm wide, large trees up to cover about 70% of this area; 3 saplings to June to remove the film or film cover grass, to prevent the ground High temperature; 4 pay attention to open drainage after rainfall.
Orchard-covered grass can be covered with grass before the rainy season. The rain can fix the grass. At the same time, the rain can promote the decay of the grass cover. Evenly spread the grass under the canopy and leave 20 cm ventilation holes in the rhizome; For 20 centimeters, the number of grasses required is generally 2000-3000 kilograms per mu; if there is not enough grass source, it can be mainly covered with tree trays; after the grass is covered, a small amount of sparse pressure soil is needed to prevent the wind from scraping grass and grass; Strengthen the prevention and control of subterranean rodents, and pay attention to fire prevention in winter. Open the waterways in the rainy season to facilitate drainage. The tree plate covers the most suitable orchards in the mountains. The flat orchard and soil in the soil are not recommended to cover the grass because the grass is easy to accumulate after the grass is covered. When pests fight drugs, they must take care of the coverings to eliminate the insects that are lurking in the grass.
