First, the medicine is not ambiguous three times after flowering
After flowering to before bagging should be sprayed three times, and the medication during this period should be based on the principle of safety.
The time of the first spraying after flowering is counted from the beginning of the large area of petals in the orchard, and the spraying begins in 7~10 days. If it rains after flowering, start spraying the first medicine after 7 days, and spray it after 10 days without rain, this spraying is mainly to prevent early defoliation and powdery mildew pathogens, and insect pests such as Kang's mealybug, red spider and leaf roller. At the same time, it is necessary to start supplementing young fruits with calcium to meet the normal growth needs of young fruits.
After flowering, the second medicine and the first medicine are separated by 7~10 days, and the second medicine depends on the pest situation of the orchard, no insecticides can be added, but aphids should be treated.
The interval between the third and second times is 7~10 days, and the interval between half a day after spraying should start to cover the film bag, and the 7 days must be completed, otherwise, it is necessary to re-spray and then set.
Second, strict determination of results is to reduce costs and increase efficiency
10 days after flowering, the fruit will be set, the earlier the better, leaving one fruit every 20~25 cm. On a branch, the small fruits in the front and back can also be thinned, and a few large fruits can be left in the middle of the high-quality flower bud segment; When the fruit is set, the center fruit is left without the edge of the flower and fruit; Leave the fruit with a crooked stalk, and leave the fruit with a straight stalk; Leave the fruit with a thick stalk, but not the fruit with a thin stalk; Leave the drooping fruit on both sides, but not the fruit on the back; Fruits with side shoots on the fruit platform, but no fruit without side shoots; leave the fruit shape upright, and leave the deviated fruit; Leave the fruit of the flower bud on the top of the short branch, and leave the fruit of the flower bud on the top of the long branch; Those who leave the fruit mouth tightly wrapped, and those who do not leave the fruit mouth open; The sick, the rusty, and the wounded will not be left behind.
Third, 4 times and 5 times of watering should be paid attention to
Water the orchard lightly by late May. Because in June, the orchard will have to control the water moderately. In June, the spring shoots of the orchard have stopped growing and entered the flower bud differentiation stage. Once watered, new shoots that have stopped growing will grow a second time, which is not conducive to the normal differentiation of flower buds. But it is also a mistake to not water the orchard if it is too dry.
In late May, it is necessary to begin to top dressing fruit trees, June is a root growth peak, is the expansion period of young fruits, is the flower bud differentiation period, is the critical period of nutrients, must be given to the fruit trees in time to supplement nutrition, to prevent nutrient interruption, affect the normal growth of fruit trees, the top dressing should be based on high phosphorus type of fully water-soluble fertilizer, plus medium element water-soluble fertilizer mineral crystals, in the case of can not be watered with a fertilization gun.
Fourth, timely bagging
After spraying the medicine three times, start bagging, the sooner the film bag is set, the better, the paper bag should not be too early, but it is not the later the better, it should be completed before the end of June, it can be extended for a week if it is not finished, and the greening will not be affected, but it is recommended that you do not choose a low-grade paper bag, which will affect the fruit surface and the effect of greening, and you should choose a high-grade paper bag.
