The golden pagodatree is a branch of numerous pagodatree species, grows in the northwest of Guizhou and south Hunan province, and is named as golden pagodatree because the produced pagodatree flower buds are golden yellow. The whole state is the best producing area for producing high-quality sophora japonica and has irreplaceable geographical advantages. The special natural factors such as soil texture, climate, etc. make the high quality of the 'gold pagodatree flower bud'. At present, the production of the golden pagodatree has been realized in two seasons. However, the phenomenon that the two-season robinia pseudoacacia flowers late and irregularly, and the like, and how to promote the high yield of the two-season robinia pseudoacacia is a technical problem in the field of planting of robinia pseudoacacia.

(3) taking the area which takes the root of the golden pagoda tree surrounded by the first annular groove in the step (1) as the center as the inner side and the area which is outside the surrounding ring as the outer side, digging a second annular groove outside the first annular groove, uniformly applying the rotten chicken manure into the annular grooves, and covering soil;
(4) pruning after picking the first flos Sophorae Immaturus, wherein the pruning method comprises the steps of keeping the branch length of the bearing branch to be 20-30cm, simultaneously stripping 4-5 leaves at the top end (cutting and not damaging leaf buds), and subtracting the overgrown branch and the diseased branch;
(5) flower bud induction: spraying low-concentration cyanamide and tween once.
Preferably, the first annular groove in the step (2) has a depth of 20-30cm and a width of 5-10 cm.
Preferably, the second annular groove in the step (3) has a depth of 30-40cm and a width of 20-30cm
Preferably, the low-concentration cyanamide in the step (5) is the cyanamide with the spraying mass concentration of 0.5%; the low-concentration tween is tween with the spraying mass concentration of 5 percent.
Compared with the prior art, the invention has the following beneficial effects:
(1) the method has the advantages of early differentiation time of the secondary flower buds and high differentiation uniformity;
(2) the method has good economic benefit, and about 80-90% of bearing branches can be subjected to secondary flower bud differentiation and flower formation after being regulated and controlled by the method, and the formed flowers are tidy.
Detailed Description
The following detailed description is to be read in connection with specific embodiments, but it should be understood that the scope of the invention is not limited to the specific embodiments. The equipment used in the examples, fertilizers, chemicals, etc., were all commercially available unless otherwise specified.
Example 1
A cultivation method for promoting high yield of two-season Sophora japonica comprises the following operation steps:
(1) after completely falling leaves in winter, vertically cutting off the robinia pseudoacacia roots in a vertical projection annular area on the periphery of the robinia pseudoacacia crown by using a root cutting machine to form a root cutting area, wherein the depth of the root cutting area is 20-40 cm, and the width of the root cutting area is the cross section of the root cutting machine;
(2) taking the area which is surrounded by the root-cutting area in the step (1) and takes the root of the acacia tree as the center as the inner side, taking the area outside the surrounding ring as the outer side, digging a first annular groove at the outer side of the root-cutting area, wherein the depth of the annular groove is 20-30cm, the width of the annular groove is 5-10cm, the root-cutting area and the first annular groove are close to each other, the interval between the root-cutting area and the first annular groove is 1-2cm, dissolving 30g of powder paclobutrazol (15 percent of effective components) in 1000ml of water, then completely and uniformly spraying the solution in the first annular groove, covering the soil to the ground height before digging, and generally leveling the soil; digging a first annular ditch after root cutting, and simultaneously and sequentially applying paclobutrazol as much as possible;
