Planting method of Myrica rubra

1, soil fertility. Young trees are mainly quick-acting fertilizers, which are applied 2-3 times a year. Adult trees are fertilized twice a year. 1. Apply 25-30kg; Burnt mud after harvest. The second is spring fertilizer, which lasts from February to March. Potassium sulfate 1.0 kg and urea 0.2 kg were applied to plants. In addition, topdressing 0.2%-0.3% potassium dihydrogen phosphate or applying 600 times liquid foliar fertilizer 1-2 times during the fruit growth period.

2, plastic trimming. In order to achieve high quality and high yield, we should give priority to popularization in the early stage, so that it can become a crown early. After the crown is formed, it is necessary to effectively control the growth, promote the formation of flower buds, achieve three-dimensional results and achieve high yield every year. Young trees usually cultivate a natural and happy crown with "one stem and three main branches" after planting, cut it off at 30-40cm, and then select 3-4 branches with vigorous growth and uniform distribution as main branches, and cultivate 2-3 auxiliary main branches on each main branch to make it distribute reasonably and clearly, and basically form a crown skeleton within 3-4 years. After the results, it is advisable to cut and lengthen lightly, mainly by thinning and deleting, to loosen the tree potential and open side branches. The upper part of the branch should be thin and the lower part should be dense, resulting in a three-dimensional effect. Pruning is mainly in February in spring, supplemented by summer (after fruit picking). Cut off branches of diseases and pests, dead branches and weak branches, sparse dense branches, retract and update drooping branches and bear weak branches.

3. When the height of the flower-promoting tree is 2.0-2.5 meters, the shoot control method is adopted to promote the formation of flower buds and realize early fruit and high yield. Branching can be used to open the crown and relieve the tree potential. At the same time, in the early period of 10 to the late period of 12, paclobutrazol is used to control shoots and promote flowers, or when the shoot growth length is 1.0cm in July and September, paclobutrazol is sprayed on the crown to inhibit the shoot growth in summer and autumn and promote flower bud formation.

Eliminate pests and diseases

Myrica rubra has fewer pests and diseases. The main pests are oyster scale, white scale, leaf roller moth, bag moth and so on. The main diseases are brown spot, cancer, etc., which should be prevented and controlled in time according to the occurrence of pests and diseases.

1. Strengthen cultivation management: improve ventilation and light transmission conditions, enhance tree vigor and improve tree disease resistance;

2. Clear the garden in time: trim and remove pests and dead branches, burn them centrally to reduce the infection of pests and diseases, or use pine alkali mixture and sulfur mixture for prevention and control;

3. Chemical control: spraying 1 0,500 times of 40% quick-killing EC or 800- 1 0,000 times of 35% quick-killing EC to control Myrica rubra nymphs in May-June and July-August; Spraying 20% pyrethroid emulsifiable concentrate 2000- 2 500 times to control bagged pests from late May to late July; From early May to mid-July, 800 times of 50% carbendazim wettable powder, 600 times of 65% mancozeb wettable powder or 800 times of 70% thiophanate-methyl were sprayed to control Myrica rubra brown spot.
