Description

Method for promoting batch maturation of sophora japonica

Technical Field

The invention relates to the technical field of production and cultivation of sophora japonica, in particular to a method for promoting the batch maturation and batch harvesting of sophora japonica.

Background

Flos Sophorae is a characteristic Chinese medicinal material, and its effective component rutin has effects of resisting inflammation, relieving spasm, resisting ulcer, inhibiting bacteria, fungi and virus, and absorbing ultraviolet. 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 content of the rutin in the golden pagoda tree in the county of the whole state is between 35 and 37 percent, and some rutin is even as high as 46 percent and is far higher than the standard limit of 15 percent in Chinese pharmacopoeia (2005 edition). The whole state is the best producing area for producing high-quality sophora japonica and has irreplaceable geographical advantages.

In the large-scale planting of the golden pagodatree, the golden pagodatree is mature at the same time, and a large amount of labor is needed for harvesting, enzyme deactivation, airing and impurity removal in a short period. Under the condition of general shortage of labor in young and strong years, the difficulty of large-batch harvesting in a short period is extremely high, and a plurality of growers can not harvest timely due to insufficient labor and miss the optimal harvesting period, thereby causing great economic loss. If continuous rainfall occurs in the mature period of the golden locust, the loss is more serious. How to promote the batch maturation of the sophora japonica so as to reduce the pressure of labor shortage of growers in the harvesting period, and the problem that the planting technologists need to solve urgently to ensure the economic benefit of the growers to the maximum extent. No research report in this aspect is found at present.

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 aims to provide a method for promoting batch maturation and batch harvesting of sophora japonica, which can be popularized and used and has a stable effect.

The technical scheme of the invention is as follows:

a method for promoting batch maturation of Sophora japonica comprises the following steps:

(1) trimming: the pruning of the sophora japonica starts after all fallen leaves, and the first pruning time is half a month after all fallen leaves are pruned; the second batch of pruning is carried out in two months after the first pruning; pruning for the third batch is carried out when the golden locust begins to sprout in spring and the length of a new sprout is 2-5 cm;

(2) regulating and controlling flower bud differentiation time: spraying paclobutrazol on the leaves of the sophora japonica which is pruned in batches respectively, wherein the spraying time is 10-15cm long of new shoots; the first batch of trimmed paclobutrazol application method is as follows: the dilution multiple of the paclobutrazol is 200 times, the paclobutrazol is sprayed for 3 times totally, the interval time of each time is 10 days, and the spraying concentration of each time is the same; the second batch of trimmed paclobutrazol application method is as follows: the dilution multiple of the paclobutrazol is 300 times, the paclobutrazol is sprayed for 3 times totally, the interval time of each time is 7 days, and the spraying concentration of each time is the same; the third batch of trimmed paclobutrazol application method comprises the following steps: the dilution multiple of the paclobutrazol is 350 times, the paclobutrazol is sprayed for 3 times totally, the interval time of each time is 5 days, and the spraying concentration of each time is the same.

Preferably, the paclobutrazol used in step (2) is a 15% paclobutrazol powder.

Compared with the prior art, the invention has the following beneficial effects:

(1) the method of the invention can reduce the labor intensity of the winter centralized pruning and improve the pruning quality. For a large planting household, if tens of thousands of trees need to be pruned in a short period, a large amount of labor is required to be hired, and the investment cost is increased. Batch trimming can then mitigate this cost. Meanwhile, batch pruning can divide the original total workload into several times, thereby ensuring the quality of each pruning.

(2) The method can reduce the pressure of labor shortage in the mature harvesting period and ensure that the picked sophora flower buds are subjected to subsequent treatment in time. Picking can be completed by hiring a relatively small amount of labor in each picking period, and subsequent processes of enzyme deactivation, airing, threshing, impurity removal and the like are completed in time, so that the quality of the sophora flower buds is ensured.

(3) The method disclosed by the invention can avoid severe weather due to mature stages, and the economic benefit of growers is ensured to the maximum extent.

(4) The method of the invention can select proper harvesting times by adjusting the trimming times. If the two batches of the golden locust are pruned in winter, the golden locust is ripe in two batches.
