1. Trim
In summer, pruning was performed twice in the bud. The first time the bud was grown to 5 cm, the buds were selected to retain the weak buds, double buds, three buds, and improperly positioned buds. The second time the new shoots grow to about 15 cm in length and combine with thinning flowers. The ratio of shoots to vegetative shoots was 3:1. According to the target yield, it is decided that the amount of shoots will be set. Generally, 3500 sticks will be set per mu.
In winter, pruning is mainly based on short shoots, combined with pruning in the middle shoots, leaving 6,000 buds per mu. During the cutting process, 3 to 5 cm protective piles are left above the clipped shoots, and the trees are subjected to short cuts and retractions according to the resulting parts and the maturity of shoots.
2. Flower and fruit management
Before flowering, trim the inflorescences, remove the 1 to 2 branches of the deputy panicles and the base, and cut back the longer branches. Remove 1 to 2 cm of the tip to make the ears perfectly compact. Sunshine rose natural fruiting is very good, to be stable fruit after the fruit size is clear when the fruit thinning.
After fruit thinning, use 40% pyrimethanil 1000 times + 20% difenoconazole 3000 times dip inflorescence, until the liquid is dry, bagging within 1 to 3 days. The bag should be kept away from the hot weather.
3. Fertilizer management
Before the sprout, topdressing 15 kg urea per acre, digging shallow ditch applied to the cover soil and pouring sprouting water. During the growth period of new shoots, 20 kg of nitrogen, phosphorus and potassium compound fertilizer was applied per acre. During the fruit expansion period, 25 kg of NPK fertilizer is applied per acre. During the color change period, 25 kg of potassium sulfate fertilizer was applied per acre. To the end of September Shiji Fei, applied per mu 4 cubic meters of chicken manure, 50 kg of NPK fertilizer. Every time after top dressing, it must be irrigated. In November, winter water is poured.
4. Harvest
After ripening, it can be hung up to the frost, no change in taste, no fruit cracking, no threshing, no fading, cool weather, and better food quality. However, the long hanging time of the tree not only affects the safe wintering of the tree, but also affects the output of the second year.
