Planting method for Salvia miltiorrhiza

Abstract

The invention provides a planting method for Salvia miltiorrhiza. The planting method comprises the following steps: construction of high ridges: deep-ploughing a target land, carrying out leveling, crushing and harrowing, constructing high ridges, and leveling the surfaces of the ridges; digging of sowing ponds on the surfaces of the ridges: starting from one end of the surface of each ridge, digging ponds at the positions of 15 cm away from two sides of each ridge, and allowing three ponds to form a group, wherein the ponds are closely adjacent, and a distance of two groups of ponds is 25 cm; application of a manure fertilizer and a pesticide: applying a fine manure fertilizer and the pesticide into the ponds, covering the surface of each ridge with a black film, and manually carrying out holing, wherein holes are in one-to-one correspondence to the ponds; sowing: irrigating water into the ponds, and after soil is fully moisturized, carrying out sowing; management in a seedling period: continuously spraying water every other day for 4 to 5 times in a rainless season; drawing-out of seedlings and sealing with soil: when a Salvia miltiorrhiza seedling grows to 10 cm high, drawing all overground stems and leaves of the Salvia miltiorrhiza seedling out from holes of the film, and compacting and sealing the basal part of the Salvia miltiorrhiza seedling with a small amount of soil; and subsequent management: regularly carrying out watering for 2 to 3 times in drought weather in an early stage, carrying out topdressing in May to August, and respectively removing flower buds once in June and August.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a planting method of salvia miltiorrhiza. Background technique [0002] The two main production and operation links of Danshen are the cultivation and sale of Danshen seedlings, field production of Danshen and product sales. These two links are continuous in production, but due to different business purposes, the production models are quite different. The fault between the two links has caused many disadvantages to the production of Danshen, mainly in the following aspects: [0003] 1. Repeated labor for raising seedling plots and transplanting plots; [0004] 2. There are serious weeds in seedlings in bare seedbeds, and it takes a lot of weeding; [0005] 3. The field of salvia miltiorrhiza for transplanting seedlings still needs to be weeded manually, regardless of whether it is covered with plastic film or not; [0006] 4. Salvia miltiorrhiza is gr...

AI Technical Summary

Problems solved by technology

[0004] 2. There are serious weeds in seedlings in bare seedbeds, and it takes a lot of weeding;

[0006] 4. Salvia miltiorrhiza is grown in bare land from June to August every year, and transplanted to the field from October to May of the following year. The seedling time is short, the seedlings are small, the growth potential is weak, the recovery period after planting is long, the lack of seedlings is serious, and the effect is not good. it is good;

[0007] 5. When the seedlings are raised from the seedbed and transplanted to the field, the roots of the seedlings are seriously damaged, the recovery period after transplanting in the field is long, the survival rate is low, and the yield in the field is not high;

[0008] 6. The long-distance transport of Salvia miltiorrhiza seedlings is bulky, severely squeezed, prone to heat, mold, and rot, causing great damage and high transportation costs;

[0009] 7. It takes a long time for seedlings to be transplanted, up to 18 months, the production efficiency is low, and the time, light, heat, water and fertilizer, and artificial utilization are not sufficient;

The disadvantage of this kind of film-covered perforation cultivation is that there is no concave pond at the perforation, which is not conducive to watering, collecting rainwater and fertilization, and it is difficult to effectively use natural rainfall, and the utilization rate of irrigation water and rainwater is low. In the early stage, the growth of salvia miltiorrhiza was slow due to insufficient water. , which affects the later production

[0017] The emergence of Salvia miltiorrhiza planted between October of the first year and April of the next year was severely delayed due to root breakage, lack of water, and low temperature during seedling emergence, and also reduced the emergence rate. Planted Yield Output Value
