Apple flower management
Every fruit grower is eager to grow apples from their own homes. However, the quality of apples needs to be managed after flowering.
Three times after the flower, the drug is vague
The first time after the flowering, the time of spraying from the large area of ​​the orchard will begin to spray the first time in 7-10 days. If it rains after flowering, the first medicine will be started after 7 days. It can be sprayed after 10 days without rain. The main prevention of this spray is the pathogen of early defoliation and the pathogen of powdery mildew. The insect pest is Kangshi powder and red spider. And other pests such as leaf curlers. At the same time, it is necessary to start to add calcium to the young fruit. After the flowering, M-JFN and the fully water-soluble Subermeimei are added to meet the normal growth of the young fruit.
The second pass after the flower is separated from the first pass by 7-10 days. The second pass depends on the insect pest in your orchard. You can add no pesticide, but remember to add the remedy for the mites.
The third pass and the second pass are separated by 7-10 days. After the spraying, the film bag should be started in the first half of the interval. It must be finished in 7 days. Otherwise, it must be re-sprayed and must not be sprayed. How many days will it take?
Strictly set the result is to reduce the cost
Set the fruit 10 days after flowering, the sooner the better, leave a fruit every 20-25 cm. On a branch, the small fruit before and after can be removed, and several large fruits are concentrated in the middle of the high-quality flower buds; when the fruit is fixed, the center fruit is left without leaving the flowers; the fruit with the fruit handle is bent, leaving the fruit handle straight. The fruit of the fruit stalk is thick, and the fruit with the fruit stalk is not left; the fruit is dripped on both sides, and the fruit on the back is not left; the fruit with the fruit tip of the fruit table is left, and the fruit without the side shoot is left; The shape is positive, the fruit is not skewed; the short-branched top flower bud fruit does not leave the fruit of the long-branched top flower bud; the fruit-bearing fruit is tight, leaving no fruit open; fruity, Rust, wounded, and will not stay.
Pay attention to watering
From the end of April to the beginning of May, the orchard should be lightly watered. Because in May and June, the orchard will have moderate water control. If there is no watering from the end of April to the beginning of May, there may be a drought in the orchard in June, but at this time the spring shoots have stopped and entered the flower bud differentiation period. Once watered, the long-term new shoots will grow twice, which is not conducive to the normal differentiation of flower buds.
In late May, the fruit trees should be topdressed in early June. June is a root growth peak, which is the period of young fruit expansion, which is the flower bud differentiation stage. It is the nutrient critical period. The fruit trees must be supplemented in time to prevent nutrient interruption and affect the fruit trees. The normal growth, this topdressing should be based on the high-phosphorus type of water-soluble fertilizer in the Zhongnongle series, combined with Mengli 28 or marine fertility, combined with medium-level elemental water-soluble minerals, can not be watered In the case, use a fertilizing gun.
Timely bagging
After three times of spraying, the bag will start to be bagged. The sooner the film bag is set, the better. The paper bag should not be too early, but it is not the sooner the better. It should be the best on June 30, but it can be extended. One week, de-greening will not be affected, but it is recommended that you do not choose low-grade paper bags, which will affect the fruit surface and de-greening effect. You should choose medium-to-high-end paper bags.
