When grapes are grown in winter, the trunk is required to have a diameter greater than 2 cm, the main chicken is about 0. 9 cm in diameter, is not too thick (greater than 1 cm), is not too thin (smaller than 0. 8 cm) and grows evenly. It's only in the second year that these plants will come to fruition. To meet these requirements, we need to start with fertilizers, water, pests, etc. Fertilizer growth, prevention of water fertilisation (1) fertilisation management: 15 gills of grape seedlings, 20 days after they sprouts, and new leaves, which grow into 6 gills of eight leaves, then water them when they grow properly
In order to promote strong growth and early formation of plants, nitrogen fertilizer should be the primary fertilizer at an early stage. At the same time, 300-500 marine psychoactive agents (roots) should be used every 10-15 days, in keeping with the principle of “more before and after” and in the later stages of growth, in order to increase plant nutrient accumulation, increase root systems, enrich the main vines, and increase the woody level, growth should be controlled. At this stage, the supply of nitrogen fertilizer can be stopped, appropriate phosphorus and potassium fertilizer can be used at the root and leaves can be applied to the face of the leaf. (2) water management: water is more conducive to the growth of the seedlings of the year than fertilizer and should be noted. After the first two waterings, the seedlings can exercise properly to force the root to dig. After growing to 10-20 cm, water is poured every half month. When the bud grows to 30 to 40 centimeters
Water is poured every 20 days to keep the soil wet and water is not watered when it is well. In the later stages of growth, the amount of water being poured down or even stopped. (3) soil management: in november, when applying the base fertilizer, the soil was covered with black cover or horticultural cloth in order to maintain moisture, increase the temperature of the ground, suppress weeds, promote the rapid growth of grapes and remove the cover. Autumn seasons, high-breed crops, melons, etc. Are not allowed to grow. Weeding in time, not growing. Set up the vines in time to guide the main vines. Good pest control can affect the growth of trees as long as one pest occurs. In the facility planting area, facilities should be built as early as possible to plant large sheds, which should cover grapes with old sheeting before they sprout. As long as the vines and leaves are not exposed to the rain, the shrubs should be removed in october. For example, in field cultivation, prior to the planting of grape seedlings, branches and vines are immersed in a 5-percent sulfur mixture and care that roots cannot be immersed, thereby killing pathogens on the seedlings and reducing morbidity。
