How to prevent and cure the cracked fruit of yellow skin?

How to prevent and cure the cracked fruit of yellow skin? Please give guidance that the growth rate of wampee fruit trees is slower than that of other general fruit trees, and the ability to shoot every year is not strong, generally about 3 times a year. If it is a fruited plant, the shoot is about 2 to 3 times a year, and the first time is the spring shoot, with spikes on the top of the spring shoot. So the spring shoot is regarded as a fruiting branch. The second time is summer shoot. If the plant has been hung with fruit, the summer shoot is usually rarely produced. Only those plants with little or no fruit in that year will sprout summer shoots. The third time is the autumn shoot, under the condition of good water and fertilizer management, the autumn shoot can be attacked twice, that is, the spring shoot can be extracted on the basis of last year's autumn shoot and become the fruiting branch of the following year. The flower bud differentiation period of wampee plants is generally from December to January of the following year after the autumn shoots are mature, so the autumn shoots are generally extracted from the fruit harvest to the middle of October. Chicken heart yellow skin includes big chicken heart yellow skin, selected big chicken heart yellow skin or long chicken heart yellow skin, and its fruit ripening period is about mid-July (the ripening period of selected chicken heart yellow skin variety is about early July). If you want wampee to release autumn shoots twice, its fertilizer and water management should be relatively strict. For example, before fruit harvest in early July, fertilizer should be applied before fruit application, so that the plant after fruit harvest can quickly restore the tree potential. However, as your wampee plant does not hang fruit this year, it is appropriate to apply fertilizer in early July and prune in the middle of July. So that the latent buds of the plant can be extracted as scheduled at the beginning of August. After the autumn shoot germinated, fertilizing again and spraying foliar fertilizer on the crown many times, in order to promote the first autumn shoot to mature as soon as possible and shoot again for the second time. However, as it is already the end of July, if the first autumn shoot is difficult to be pulled out in early August. After entering September, the temperature gradually turns cool, and the amount of rain decreases in autumn, and the humidity is relatively low. in case the second autumn shoot can not be released as scheduled at the end of September and the beginning of October, but delayed to be pulled out after the middle of October, the second autumn shoot will affect the flower bud differentiation of the plant and the flower formation of the following year when the second autumn shoot is difficult to mature and enrich in the middle and late November. To say the least, spring shoots have been produced in your yellow orchard this year, but the summer shoots are not very neat, which indicates that the tree strength of the plant is not very uniform. However, if you draw strong autumn shoots on the basis of spring and summer shoots, the normal growth of three shoots can basically accumulate nutrients that can make flowers grow next year. To take a step back, the root system of wampee tree is relatively shallow, that is, in the case of normal drought in winter, it has a greater degree of inhibition on the root system of wampee. Therefore, wampee plants are generally not easy to shoot in winter and can enter flower bud differentiation smoothly. Therefore, if you orchard irrigation system irrigation capacity. When there is not enough assurance to meet the sufficient water supply needs of the plant in the autumn drought, it is not appropriate to consider putting the autumn shoot twice. In addition, the reference fertilizer application amount and types of autumn shoots. It is suggested that autumn shoot fertilizer should not be applied too much organic fertilizer, but should be reserved for next year before and after Greater Cold. Each plant can consider to choose 0.2kg compound fertilizer at 15:15:15, add 0.2kg urea to rarefied fecal water, and cover the soil after opening a shallow trench under the crown dripping line. When the autumn bud is about 3-5 mm, attention should be paid to the spraying control of leaf miner moth. Foliar fertilizer should be added to use drugs, such as humic acid Kangbao, or algin Waldeb, etc. The drugs for the control of leaf miner moth can be selected as follows: 50% tiger frog EC (difluoronitrile) 500x solution, or 3.2% jinmevir salt microemulsion (methamidazole chloride) 5000 times solution, or 20% chlorpyrifos EC (chlorpyrifos) 800x solution, every 7 days, alternate drug control, spray 3 times for 4 times.
