Description
Technical Field
The invention relates to the technical field of planting of golden pagodatree, in particular to a cost-saving and efficiency-increasing cultivation method of golden pagodatree.
Background
The dried flower bud of pagoda tree (Sophora japonica L.) belonging to the family Leguminosae is a special traditional Chinese medicine material, is rich in rutin, luteolin and other chemical components, and the rutin can keep the normal tension of capillary vessels, reduce the permeability of the capillary vessels, restore the normal elasticity of the bleeding capillary vessels due to increased brittleness, has the effects of resisting inflammation, relieving spasm, resisting ulcer, inhibiting bacteria, fungi and viruses and absorbing ultraviolet rays, is widely applied to medicines, health-care foods and cosmetics, and has high commercial value. Compared with other plants, the sophora flower bud has high rutin content and low extraction cost, and is a main raw material for industrially extracting rutin.
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 rutin content of the golden pagodatree flower bud in the whole state in Guangxi is between 35% and 37%, and some rutin content is even as high as 46%, which is far higher than the standard limit of 15% in Chinese pharmacopoeia (2005 edition), and is the best product in the pagodatree flower bud. The whole county is the best production place for producing high-quality sophora japonica and has irreplaceable regional advantages. The special natural factors such as soil texture, climate, etc. make the high quality of the 'gold pagodatree flower bud'. 98% of the sophora japonica in the international market comes from China, the annual demand is more than 15000 tons, and the total yield of the sophora japonica in China is only 9000 tons at present, so that the demand of the international market is far from being met. Within the next 20 years, the demand trend of sophora japonica is expected to increase by 20% year by year. Therefore, the robinia pseudoacacia industry has very good development prospect.
At present, the planting area of the golden pagoda tree in the county of the State is 27 ten thousand mu, but according to investigation, the planting method adopted by pagoda farmers is to plant annual grafted seedlings, about 50 plants are planted in each mu, the planting can be carried out in 4-5 years, the land resources are not fully utilized, the early-stage investment cost is high, the phenomena of tip washing and the like are serious, and the high yield can be realized in a long time.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Disclosure of Invention
The invention provides a cost-saving and efficiency-increasing golden pagoda tree cultivation method aiming at the problems of high early-stage investment cost, poor planting effect and long time for realizing high yield in the existing golden pagoda tree planting process, which comprises the following steps:
(1) planting annual graft robinia pseudoacacia seedlings in 3-4 months, setting the row spacing and the spacing of the graft robinia pseudoacacia seedlings to be 1m, digging planting holes before planting, and applying farmyard manure in each hole;
(2) pruning the first three young trees: selecting 2 symmetrically distributed young shoots after a grafted seedling of the robinia pseudoacacia sprouts germinates, reserving the 2 symmetrically distributed young shoots, wiping the rest young shoots, topping when the vertical length of the reserved young shoots is 60cm, reserving 10-15 cm, and immediately applying a compound fertilizer after topping; repeating the operations of topping and fertilizing for 3-4 times in the first year of field planting of the grafted robinia pseudoacacia seedlings, repeating for 3 times in the second year and repeating for 2-3 times in the third year to obtain shaped robinia pseudoacacia seedlings;
(3) digging out the shaped Sophora japonica seedlings at the end of the third year or at the beginning of the fourth year, keeping the root systems as complete as possible during digging, then cutting off the main roots and other root systems with the diameter larger than 0.5cm from the base part, and then soaking the reserved root systems in a rooting solution;
(4) planting: and (3) field planting in the selected garden, excavating field planting holes according to the row spacing and the space of 2m, field planting the robinia pseudoacacia seedlings processed in the step (3), wherein the backfill soil is mixed soil of chicken manure and soil.
Preferably, the planting hole in the step (1) is 40cm × 40cm × 40cm in specification.
Preferably, 1.5-2.5 kg of farmyard manure is applied to each hole in the step (1); more preferably, 2kg of farmyard manure is applied in each hole;
preferably, the compound fertilizer in the step (2) is a water-soluble compound fertilizer with nitrogen, phosphorus and potassium in a ratio of 15:15:15, 150g of the compound fertilizer is applied to each plant, and the compound fertilizer is uniformly irrigated to the base of the plant after being dissolved in water;
preferably, the rooting solution in the step (3) contains 50mg/L of ABT1 rooting powder 50mg/L, ABT2 rooting powder, and the time for soaking the root system in the rooting solution is 1.5-2.5 h; more preferably, the time for soaking the root system in the rooting solution is 2 h.
Preferably, the size of the planting holes in step (4) is 1m × 1m × 0.8 m.
Preferably, the mixed soil in the step (4) is obtained by mixing decomposed chicken manure and soil according to the volume ratio of 1: 2.
Compared with the prior art, the invention has the following beneficial effects:
(1) and the land cost and the management cost are saved by intensive cultivation in the earlier stage:
the planting method has the advantages that the early-stage intensive planting is carried out, the row spacing of the grafted seedlings of the acacia plants planted in the first to third years is only 1m, about 650 plants can be planted in each mu, only the original 1/4 land is needed, and 3-year land renting can be continuously saved, so that the land renting cost is greatly reduced. In addition, the seedlings are planted densely, the operation is more convenient during topping and shaping, and more labor cost can be reduced.
(2) The intensive shaping pruning in earlier stage can be convenient for form the high-yield tree form fast:
the conventional pruning method of the golden locust tree in the juvenile period is 1-time pruning in 1 year, and according to the method, a high-yield tree form can be formed only after 6-7 years, the first year of transplanting and planting in the method can be put into production in a small scale, and the high-yield period can be reached after 2-3 years.
(3) Avoiding the occurrence of shoot rushing of the golden locust:
the root system of the golden pagodatree grows fast, the main root is developed by the conventional planting method, the shoot is easy to rush at the later period, and the golden pagodatree form is basically formed after the golden pagodatree is shaped for 3 years and can be used for generation. Meanwhile, the main roots are cut off and transplanted, the germination of the lateral roots of the plants is promoted, the absorption of nutrition is facilitated, the vegetative growth is converted into reproductive growth, and high yield is easily obtained.
