(1) After replanting, transplanting and planting 1 month, if dead seedlings are found, replanting should be carried out immediately. In the spring of the following year, if the seedlings are missed and replanted, large seedlings with soil that are more than two years old must be used.
(2) Intertillage weeding and fertilization are carried out 3-4 times a year. For the first time, from the end of April to the middle of May, weeds were cut off or weeded with chemical herbicides such as glyphosate; Loosening soil around plants, spreading 20-30g of urea on each plant, shoveling soil to cover fertilizer and spreading grass to cover the surface; For the second time, from late June to early July, weeding, shallow loosening and fertilization were carried out, with 50 grams of urine per plant and 30 grams of compound fertilizer, and the soil was used to cover the fertilizer and grass was used to cover the surface; For the third time, in1February, mow (dig) miscellaneous shrubs and vines on the planting belt, apply decomposed soil miscellaneous fertilizer10 ~15 kg or compound fertilizer 0.5 ~1kg to each plant, mix well with loose soil, and finally fill the ditch with loose soil.
With the growth of Illicium verum, while intertillating and loosening the soil, dig deep around the plant and gradually expand the scope to promote root growth.
(3) Plant shape management seedling Illicium verum forest, cutting off dead branches and diseased branches, and protecting the trunk and lateral branches, so as to cultivate strong trunk and sufficient lateral branches at all levels, and form a good crown shape with tall trunk and dense branchlets.
In the first and second years after afforestation, only one robust bud is left to grow into the trunk, and all the other buds are erased. Cut off the overgrown upright branches, overlapping branches, weak branches and diseased branches in time to promote a good crown shape with obvious trunk and strong lateral branches.
(4) Young Illicium verum trees are fond of shade, and tall crops such as bananas and corn can be intercropped between young forests within 2-3 years after planting, which can not only shade and keep warm, but also promote the growth of young forests, make full use of soil fertility and increase economic income.
2. The management of the first fruit period is the 6th ~15th year after Illicium verum afforestation. During this period, the stems, branches and roots grow rapidly, and at the same time, they gradually enter the flowering and fruiting period, which is a period of equal emphasis on vegetative growth and reproductive growth of Illicium verum.
(1) At the first fruit stage of fertilization, the plant growth is large, and the flowering and fruiting are increasing year by year. When applying fertilizer, the proportion of phosphorus and potassium should be gradually increased. Fertilize 4-5 times a year, apply fruit-protecting and shoot-promoting fertilizer before spring shoots and young fruits develop in 1 ~ February, and deeply apply high-quality compound fertilizer1kg or cooked cake fertilizer 1.5 kg under the crown edge for each plant; In the end of April, the fertility fertilizer for strong fruit was applied, and the special fertilizer for octagonal was applied in a deep way 1 kg per plant, and 0.2 ~ 0.3 kg of biological potassium fertilizer was mixed; From late June to early July, strong fruit and strong tip fertilizer were applied, and each plant was applied with 5% ~ 8% calcium magnesium phosphate fertilizer to make 2 kg of mature cake bran fertilizer; Apply baoguo rejuvenation fertilizer before harvesting autumn fruits in 10, and apply 5 ~10 kg of cooked chicken manure or 0.5 kg of potassium chloride and 0.4 kg of calcium superphosphate to each plant; 12 months, apply decomposed soil miscellaneous fertilizer on the green soil in the ditch.
(2) Tree management: Carry out comprehensive pruning and plastic work in May and1February every year, and cut off the overgrown and disturbing crown branches, weak branches, cross branches, dead branches, diseased branches and insect branches from the branch base.
(3) Weeding Chemical weeding is generally adopted in this period. Chemical weeding is carried out twice a year, in March-April and June-July, respectively, and weeding is carried out with glyphosate and pesticide.
After Illicium verum enters the full fruit stage, the plant grows tall and can be managed with reference to the first fruit stage if conditions permit.
