Embodiment 1

[0056] Example 1: Analysis of climate, soil and plant characteristics in the Yellow River Delta region

[0057] 1. Climate Analysis

[0058] like Figure 2-3 As shown, in the Yellow River Delta area, spring drought—summer flood—autumn coolness—winter dryness; at the same time, the annual precipitation is 547 mm, and the annual evaporation is 1887 mm, which is 3.5 times the annual precipitation, which is also an important cause of serious soil salinization. reason.

[0059] 2. Soil characteristics of the Yellow River Delta (fluvo-aquic soil)

[0060] Table 1 Characteristics of soil fertility in the Yellow River Delta

[0061]

[0062] Remarks: The level is based on the grading standard of the second national soil census, which is divided into 6 levels.

[0063] It can be seen from Table 1 that except for greenhouse vegetable plots and orchards, the organic matter content and nitrogen content of other plots are very low, and the soil is poor.

[0064] 3. Salt analysis

Embodiment 2

[0073] Embodiment 2: Construction of the ecological production community of Akiras sinensis-Saponaria

[0074] 1) High platform and low furrow construction

[0075] Saline-alkali land: moderate saline-alkali land, the initial salt content is about 0.23%;

[0076] First, in the saline-alkali land of the Yellow River Delta, such as figure 1 The shown high platform and low furrow; its height is 30cm, the width of the low furrow is 2.0 meters, and the width of the high platform is 1.2 meters;

[0077] 2) Ecological community construction

[0078] On the high platform, 4 rows of Muxiang (species: Tumuxiang) are planted, with a row spacing of 30 cm and a plant spacing of 30 cm; on a low border, 2 rows of saponins are planted, with a row spacing of 1 meter and a plant spacing of 0.5 meters.

[0079] Tumuxiang: The medicinal part is the dry root, a biennial herb, happy in light, and the plant height is 1-2 meters. Tumuxiang is not drought-tolerant, the growth conditions are not ha...

Embodiment 3

[0100] Example 3: Astragalus-saponica ecological production community construction

[0101] 1) High platform and low furrow construction

[0102] Saline-alkali land: moderately saline-alkali land, the initial salt content is 0.23%;

[0103] First, in the saline-alkali land of the Yellow River Delta, such as figure 1 The shown high platform and low furrow; its height is 30cm, the width of the furrow surface is 2.0 meters, and the width of the high platform is 1.2 meters.

[0104] 2) Ecological community construction

[0105] Plant 4 rows of Astragalus membranaceus on the high platform, with a row spacing of 30 cm and a plant spacing of 15 cm; on a low border, plant 2 rows of saponins, with a row spacing of 1 meter and a plant spacing of 0.5 meters.

[0106] Astragalus: The medicinal part is the dry root, a perennial herb with a plant height of 0.6-1.2 meters. It likes light and coolness, is resistant to cold and drought, and is afraid of heat and waterlogging. It is suitabl...

Abstract

The invention discloses an ecological producing method of traditional Chinese medicines in saline-alkali soil of the yellow river delta. The method includes the steps of preparing dais and low ridge in saline-alkali soil of the yellow river delta, covering the dais with degradable waterproof black mulch, covering low ridge with garden black ground fabric, sowing (transplanting) traditional Chinese medicines and making all soil except for the traditional Chinese medicines covered so that the aims of restraining weed growth and resisting saline and alkali can be achieved through light shielding, soil moisture preservation and water retention under the black mulch (black ground fabric). According to the characteristics of complementation of medicinal parts, light requirement characteristics, plant height spaces, water and fertilizer characteristics and salt resistance characteristics, different traditional Chinese medicines are planted on dais and low ridge for ecological community construction. High-quality organic fertilizer is adopted as base fertilizer, no chemical fertilizer is applied, and pesticide applying, topdressing, irrigating and weeding are generally not needed in the whole planting process. By means of the producing method, the aims of increasing the yield of the traditional Chinese medicines and improving saline-alkali soil of the yellow river delta can be achieved.

Description

technical field [0001] The invention relates to an ecological production method of Chinese medicinal materials in saline-alkali land in the Yellow River Delta, belonging to the field of agricultural technology. Background technique [0002] The Yellow River Delta is an alluvial plain formed by the Yellow River carrying a large amount of sediment in the Bohai Sea depression. The groundwater is shallowly buried and highly mineralized, and the natural evaporation is strong, so that the underground salt is easy to rise to the surface, resulting in soil salinization. At the seaside, the seawater evaporates after repeated immersion, and the saline-alkali components are gradually deposited, which in turn leads to serious salinization of the soil in the Yellow River Delta. Among them, the area of ​​salinized land in the Yellow River Delta area is 442,900 hm 2 , accounting for more than half of the total area of ​​the whole region, among which, 236,300 hm of heavily salinized soil a...
