Summer and autumn is the most vigorous growth of pomegranate, and it is also the fruiting period of flowering. Its management should pay attention to the following technical links. 1. Fertilization For unsapling saplings, apply one fertilizer after two-thirds of the flowers and one month before the maturity of the fruit. In addition to the fertilization of the trees that have become forested, in addition to the above two fertilization, sprouting occurs. In the early stages of buds, additional fertilizer is needed. The types of fertilizers were mainly nitrogen and phosphorus fertilizers in the early stage and potassium fertilizer in the later stage. The amount of fertilizer to be used depends on the number of results. There are fewer results and the amount of fertilizer can be less, and vice versa. 2. In the summer and autumn, the pomegranate is a kind of tree that is very fond of light. The branches of the canopy are distributed densely and densely so that both the inside and the outside can be airy and transparent. On the basis of winter and spring renovations, topping will be carried out in the summer to shorten or remove tender tips from the shoots. We should also pay attention to brushing off buds to remove excess sprouts in order to reduce the competition for nutrients and at the same time be conducive to the reasonable distribution of branches and leaves. , conducive to air and light. 3, preserved flowers and sparsely flowering and fruiting pomegranate is asexual flower, the abortion rate of pistil is high, generally only 10-25% of the complete flower, so the fruit setting rate is relatively low. The flowering period of pomegranate is more than one month. According to the sooner or later of flowering, it is divided into head lice, two pods, three pods and end pod flowers. The total flowering and fruit setting rate of the first three pods determines the level of yield. The fruits of the head flower are larger in size, while those in the late flower shape are smaller. Therefore, if multiple results are needed to achieve high yield and quality, the total number of flowers and fruit set rates of head lice and second pod flowers must be increased. For this reason, degenerate buds should be eliminated promptly on the basis of rational fertilization and pruning of the four seasons. The difference between a complete flower and a degraded flower is that the fully flowering ovary is hypertrophy, the appearance is peanut-like, the pistil is higher or equal to the anther of the stamen, and the degenerate flower is the ovary thin, the appearance of the horn, the pistil is lower than the anther. 4, the main pest control Pomegranate diseases mainly dry rot and early defoliation. If diseases are found in summer and autumn, Bordeaux liquid can be used before flowering. Tuobujing liquid can be used during flowering. After prolonged flowering, the sterilizing period of young fruit can be sprayed with anti-virus cloth or tetritis, sprayed once every 7-10 days, and sprayed several times in succession. One month before fruit picking, the drug was stopped. In addition, the beginning of bagging at the young fruit period also has a good effect on reducing the condition of dry rot. Pomegranate main insect pest provocation can use sweet and sour liquid to kill during the eclosion period, and can be controlled by killing pine nut liquid during the incubation period.
