I. Garden selection
Soil fertility, sunny, sandy soil should be chosen. The soil pH 6.5-8.0 should be suitable. The soil drainage is better. Most of the regions in north latitude between 40°C and 32°C can be planted. The area is the best at an altitude of 400 metres. The establishment of gardens is strictly forbidden in stonefruit trees.
Second, a reasonable choice of seedling stock combinations
At present, large stocks of cherry seedlings on the market are disorderly and can be broadly divided into European wild cherry (Mahali, Gisena), Chinese cherry (Benxi wild cherry, Laiyang dwarf), sour cherry (Daqingye, ZY-1) and so on. According to local conditions, choose the seedlings you need.
Third, a reasonable close planting
Fertile soil areas, extensive management, can be used to set up 4 to 5 row spacing, slightly poor soil conditions can choose 3 ~ 4m row spacing to build gardens, dwarfing fine management, can be used 2m ~ 4m row spacing establishment.
Fourth, the use of advanced tree
At present, the world's most advanced countries in the production of large cherries are free-spindle or slender spindles. The height of the rod is 80 to 90cm. Evenly, 10 to 15 main branches are scattered along the main rod 20 to 30cm. The main branch is flattened to 90 degrees, and the heart is picked in time. Urging the branch.
Five, Qiao Shui fertilizer
1 Large cherry roots are generally distributed within 1m of the soil, and the roots are shallow. Irrigation can be used for furrow irrigation. Drip irrigation and micro-spraying techniques are available where conditions permit.
2 fertilization can be divided into three times: the first winter basal fertilization should be dominated by farmyard manure. The second flowering topdressing, generally spraying foliar fertilizer at the early stage of full bloom, spraying 300 times borax or 600 times potassium dihydrogen phosphate every 5 days, can increase the fruit setting rate. Generally do not top-dressing during hard-core development to avoid affecting fruit quality. The third time after top dressing after fruit-picking, when flower bud differentiation is critical, 2 kg of compound fertilizer can be applied per plant.
3 should pay attention to the application of nitrogen fertilizer, more scale potassium fertilizer.
Six, pay attention to pest control
Big cherries have a short history of planting in China and have fewer pests and diseases. The detection of pests and diseases should be based on local conditions and symptomatic control.
One of the main pests of Prunus persicae was mainly Prunus persicae, Pseudrachosanthes, Daqingye, P. oleifera, pests of leaf buds, beetles, stink bugs, yellow moths, and peach moths.
2 Diseases mainly include cherry cancer disease, perforated brown spot disease, fluidized gum disease, and special attention to pear ring spot necrosis disease. It is a key target of national quarantine inspection. Special attention should be paid to the introduction of nursery stock. Once it is discovered that the whole garden is completely destroyed.
(3) Underground pests have devoured the roots of sakura seedlings, causing serious deaths of the saplings. The oil squash monocultures the roots of the roots of the larvae, and it is also easy to cause saplings to die.
