Problems solved by technology

98% of Sophora japonica in the international market comes from China, and its annual demand is more than 15,000 tons. However, the current national total output of Sophora japonica is only 9,000 tons, which is far from meeting the demand of the international market.

Embodiment 1

[0026] A cultivation method for promoting secondary flowering of golden locust tree, comprising the steps of:

[0027] (1) Fertilization in winter: apply basal manure in winter with the method of covering soil after the deep 20cm annular ditch is applied; Described basal manure is that every plant applies the duck manure of 10kg;

[0028] (2) fertilization before the 1st Sophora japonica harvest: choose to apply high-nitrogen compound fertilizer 15 days before the 1st Sophora japonica harvest, with a deep 15cm ring-shaped ditch and cover soil; the high-nitrogen compound fertilizer Nitrogen: phosphorus: potassium = 22:9:9, the application amount is 0.5kg / plant;

[0029] (3) Pruning: pruning is carried out simultaneously after plucking Sophora japonica for the first time; the method of pruning is: the remaining branches of the fruiting branches are guaranteed to be within 20cm, and the top 4 leaves must be peeled off at the same time, so as not to hurt the leaf buds. The distan...

Embodiment 2

[0034] A cultivation method for promoting secondary flowering of golden locust tree, comprising the steps of:

[0035] (1) Fertilization in winter: apply basal manure in winter with the method of covering soil after the annular ditch of deep 30cm; Described basal manure is that every plant applies the duck manure of 10kg;

[0036] (2) Fertilization before the 1st Sophora japonica harvest: choose to apply high-nitrogen compound fertilizer 20 days before the 1st Sophora japonica harvest, with a deep 20cm ring-shaped ditch and cover soil; the high-nitrogen compound fertilizer The nitrogen: phosphorus: potassium = 22:9:9, the application amount is 1.0kg / plant;

[0037] (3) Pruning: pruning is carried out simultaneously after picking the Sophora japonica for the first time; the method of pruning is: the remaining branches of the fruiting branches are guaranteed to be around 30cm, and the top 5 leaves must be peeled off at the same time, so as not to hurt the leaf buds. The distanc...

Embodiment 3

[0042] A cultivation method for promoting secondary flowering of golden locust tree, comprising the steps of:

[0043] (1) Fertilization in winter: apply basal manure in winter with the method of covering soil after the annular ditch of deep 25cm; Described basal manure is the duck manure that every plant applies 10kg;

[0044] (2) Fertilization before the 1st Sophora japonica harvest: choose to apply high-nitrogen compound fertilizer 18 days before the 1st Sophora japonica harvest, with a deep 16cm ring-shaped ditch and cover soil; the high-nitrogen compound fertilizer Nitrogen:phosphorus:potassium=22:9:9, the application amount is 0.8kg / plant;

[0045] (3) Pruning: pruning is carried out simultaneously after picking the Sophora japonica for the first time; the method of pruning is: the remaining branches of the fruiting branches are guaranteed to be within 25cm, and the top 4 leaves must be peeled off at the same time, so as not to hurt the leaf buds. The distance between t...

Abstract

The invention belongs to the technical field of production and cultivation of gold Sophora japonica L., in particular to a cultivation method for prompting second bloom of gold Sophora japonica L.. The method comprises the following steps: (1) winter application: application of base fertilizers in winter at the depth of 20-30 cm by circular furrow application and earthing; (2) fertilizer application prior to first harvesting of sophora flower buds: application of high-nitrogen compound fertilizers 15-20 days prior to first harvesting of sophora flower buds at the depth of 15-20 cm by circular furrow application and earthing; (3) pruning: picking first sophora flower buds while pruningfirstsophora flower buds; (4) branch promotion: spraying shooting agents 1-2 times prior to twice sprouting after pruning to keep sophora neat and tidy and sprout new branches; (5) mixing leaf fertilizers and pesticides and spraying 1 to 2 times after sprouting such that growth new branches is promoted while occurrences of pests and diseases are avoided; (6) induction of floral buds: spraying 2000 times of compound sodium nitrophenolate and 200-400 times of paclobutrazol 1 to 2 times after secondary branches turn green in order to promote flower bud differentiation. The cultivation method for prompting second bloom of gold Sophora japonica L. has the following beneficial effects: sophora flower buds are excellent in appearance and inherent quality; high yield of sophora flower buds is easily realized; and economic benefit is great.

Description

technical field [0001] The invention belongs to the technical field of production and cultivation of golden locust tree, in particular to a cultivation method for promoting secondary flowering of golden locust tree. Background technique [0002] Sophora japonica L. is the dried flower bud of the leguminous plant Sophora japonica L. It is a characteristic Chinese medicinal material rich in chemical components such as rutin and yellow alkali. Rutin can maintain the normal tension of capillaries, reduce their permeability, restore the normal elasticity of capillaries with increased fragility and bleeding, and also have anti-inflammatory, antispasmodic, anti-ulcer, anti-bacteria, fungus and virus and absorb ultraviolet rays. , is widely used in medicine, health food and cosmetics, and has high commercial value. Compared with other plants, Huai Mi has high rutin content and low extraction cost, and is the main raw material for industrial extraction of rutin. [0003] Jinhuai is...
