In mid-season mature apple varieties matured in September and the growth of the tree entered the later period. The management points for this period are:
The mid-maturing varieties of Marshal timely harvesting varieties should be harvested about 145 days after the fall, that is, in early September, at this time, the appearance of the fruit luster, full coloring. The golden crown should be collected about 155 days after flowering, that is, in the middle or late September. At this time, the background color of the fruit surface is yellow-green. Picking is generally based on the lower part of the first crown and the upper part of the rear crown; the outer part of the first canopy and the inner canopy of the rear canopy are sequentially carried out, and the result is to protect the result branches and prevent damage to the fruit branches and damage to the flower buds. If the fruit is intact, do not remove the fruit handle and gently handle the fruit to reduce bruising.
Soil and fertilizer water management should strengthen the cultivating soil in order to maintain loose soil and good ventilation, and create a good soil environment for root growth and development. The basal fertilizer is applied in time after the harvest of the medium-maturing varieties of fruit trees. Basal fertilizer is dominated by organic fertilizers, and an appropriate amount of quick-acting fertilizer or fruit tree-specific fertilizer is added. The amount of fertilizer used accounts for 60%-70% of the total amount of fertilizers in the year. Many years of experiments have proved that the Anchile organic nutrient series fertilizer produced by the Golden Camel Pharmaceutical Company in Ordos, Inner Mongolia, has achieved remarkable results and is deeply loved by fruit farmers. Should take the ring groove and strip groove fertilization. The ring groove fertilization can be watered immediately after spreading at the outer edge of the canopy. It is not necessary to dig the ditch, which saves manpower investment and is regarded by the fruit farmer as lazy man quick-dissolving fertilizer. After the mid-maturing varieties were harvested, they were sprayed with foliar fertilizer every 10-15 days to increase the photosynthetic function of the leaves and delay the defoliation. To properly control the supply of water, and pay attention to do a good job of flood prevention work, in order to facilitate fruit coloring and improve the appearance of quality.
Late-maturing varieties of fruit management began in late September, the bagging of red Fuji and other late-maturing varieties of bags, picking leaves, transfer fruit, shop reflective film and other processing. After removing the bag, the leaves of the fruit and the leaves within 5 cm from the fruit were picked, and after 3 to 5 days, other shaded leaves were picked. About 10 days after removing the bag, when the positive side of the fruit has been fully colored, the fruit is gently lifted and turned by 90-180 degrees so that all parts of the fruit can fully see the light and be evenly colored. Picking leaves and turning fruits should be carried out on cloudy or cloudy days. Sunny weather should be carried out after the temperature drops at 4 pm.
