How to eliminate the age of bayberry by planting bayberry

Red bayberry is a famous characteristic fruit tree in China, which is mainly distributed in the south of the Yangtze River Basin.

1. In the year of fertilizer and water management, annual vegetables or green manure can be planted in woodland to improve soil fertility. Young trees are mainly quick-acting fertilizers, with combined application of nitrogen, phosphorus and potassium, and adult trees are topdressing twice a year, the first in late winter and early spring before sprouting and shoots, and the second after fruit harvest, accounting for 50% of the annual fertilizer application. In addition, we should do a good job in soil improvement and eliminate waterlogging to ensure the high quality and high yield of red bayberry.

Second, the shape of the red bayberry tree is mainly natural round head. The pruning of young trees is mainly a fixed dry shape to cultivate early-bearing and high-yielding trees. Generally use "one stem and three main branches" natural happy crown. The pruning of adult trees is mainly to cultivate the population structure of high yield, adjust the relationship between growth and fruiting, and promote sustainability, high quality and high yield.

Third, the annual control of red bayberry is a typical fruit tree with regular alternate fruit year after year, so overcoming the annual fruit is an important project in the production of red bayberry, which can be regulated by technical measures such as ring cutting, promoting flower and fruit protection, thinning flower and fruit and so on. The main results are as follows: 1. the traditional measure of ring cutting, promoting flower and fruit, promoting flower and fruit is peeling or using chemical hormone, this method can get good short-term benefit, but it does great harm to the tree potential, and serious can lead to the phenomenon of dead tree. At present, the technology of ring cutting and smearing pollution-free cationic surfactant "Huawang 2" is widely used to control shoots and promote flowers, improve fruit setting rate, and eradicate years. 2. Big branch pruning for adult bayberry trees with laissez-faire growth, the methods of "cutting high branches, controlling tree crown", "cutting inner branches and opening skylight" are adopted for adult bayberry trees. For newly planted young trees, the method of "first release and then pruning" can be implemented, that is, growth is allowed in the first year, and then gradually adjusted to dwarf and open tree shape after the beginning of fruit in the fourth year. 3. More potash fertilizer should be applied scientifically, once a year. Less phosphate fertilizer, because too much phosphate fertilizer, often resulting in more fruit, a small, poor quality, aggravating the phenomenon of big and small years. Suitable application of nitrogen fertilizer to promote the expansion of young fruit. Young trees are suitable to apply chemical fertilizer, while adult trees mainly apply farm manure.

Fourth, the resistance of bayberry to diseases and insect pests is strong, and there are few diseases and insect pests. The main pests are scale, leaf roll moth and bag moth. The main diseases are brown spot, cancer and so on. 1, chemical prevention and treatment: cancer disease: after the rain in spring and autumn, the disease can be removed with a sharp knife, and then "tree protection general" lotion is applied to the wound to quickly dry up and peel off the disease spot and remove the bacterial source. Brown spot, at the initial stage of the disease, use 50% carbendazim 500 color 600 times solution or 70% methyl topiramate 800 times solution or 65% Desen zinc 600 times solution + "new high fat membrane", spray the crown, spray once in 10 days, spray 2 times for 3 times. 2. Strengthen cultivation and management, strengthen tree potential, cut off diseased branches and dead branches in time, smear "callus anticorrosive film" in time to protect the wound, 3, clear the garden in winter, remove fallen leaves and weeds, and concentrate on burning. then the whole garden was sprayed with 100-fold solution of "tree protection general" to sterilize and disinfect.
