1. After the hard cherry period, the topdressing of soluble potassium sulfate should be carried out along the water, about 6 kg per acre. If the soil is hardened, it will also affect the absorption and utilization of calcium. It can be flushed into no-tillage when watering The preparation can loosen the soil, increase the permeability of the soil, and improve the vitality of the root system. After the big cherry is set, spray a 0.2% potassium dihydrogen phosphate solution + brassinolide + various trace elements amino acid foliar fertilizer once every 7 to 10 days. In the later period, 0.3% soluble potassium sulfate + Tianda 2116+1000 times liquid calcium magnesium zinc boron can be sprayed on the big cherry, which can increase the sugar content of the cherry and improve the appearance of the big cherry.
2. Some farmers grow large cherries, which have a late appearance and poor sweetness. These are mostly related to fertilization and field management. For example, nitrogen fertilizer is one of the commonly used chemical fertilizers. Too much nitrogen fertilizer is applied. The branches of large cherry trees are luxuriant. The vegetative growth prevails, and the reproductive growth is relatively lagging. This will not only reduce the fruit setting rate of large cherries, but also cause large Cherries are colored late and the sweetness is reduced. Therefore, the management of fertilizer and water for large cherries is extremely important. If you want to achieve good coloring, early ripening and high sweetness, you should pay attention to the full rot when fertilizing. Farm fertilizer is the best, reduce the habit of simply using nitrogen fertilizer, and use the three major elements of nitrogen, phosphorus, potassium and a variety of trace elements calcium, zinc, boron, especially in the later stage of the growth of large cherries. There is no shortage of potassium in the soil, and excessive use of nitrogen fertilizer will also affect the absorption and utilization of potassium by big cherries.
3. The large cherries planted in the greenhouse can increase the temperature accumulation of the large cherry fruit. The temperature difference between day and night can be increased. The temperature during the day is kept at about 28-30 degrees, and it is maintained at 10 degrees at night. Sugar content. The widening of the temperature difference between day and night is helpful to increase the sugar content of the fruit. We all know that Xinjiang cantaloupe has high sugar content and good flavor. This is closely related to the local climate and the large temperature difference between day and night. Therefore, the cherries planted in the greenhouse, spring After the results, using the convenience of greenhouse insulation to gradually increase the temperature difference between day and night has a positive significance for increasing the sugar content of large cherry fruits.
