[0003] In the prior art, Chinese patent 201510648522.7 discloses the crop rotation of Astragalus membranaceus and gramineous crops; Chinese patent 201410851520.3 discloses the crop rotation of Astragalus membranaceus with rhubarb and corn, which solves the continuous cropping obstacle of Astragalus membranaceus to a certain extent, but in the Astragalus membranaceus cultivation area, only Potatoes, corn, broad beans, oats and other low-efficiency food crops, driven by economic interests, most drug farmers would rather serious occurrence of Astragalus membranaceus diseases and insect pests, and seldom carry out reasonable crop rotation

Embodiment 1

[0073] Select the black land with deep soil, flat terrain, loose soil, and convenient irrigation and drainage to carry out deep plowing before transplanting Astragalus, the depth is 30cm, and apply 20000kg hm of decomposed farmyard manure -2 Combined application of ternary compound fertilizer 600kg·hm -2 , shovel off the ground topsoil to make the ground level; Plant Astragalus membranaceus on March 15th, plant Astragalus membranaceus with plastic film covering method, place Astragalus membranaceus seedlings in the same direction and parallel to the ground, keep the seedlings in line, with the spacing between plants as 10cm and row spacing as 35cm, Plant Astragalus membranaceus, the tail of the seedlings is evenly covered with topsoil, the thickness of the covering soil is 4cm, and the seedlings are required to be covered tightly, and 195,000 seedlings are preserved per hectare; Irrigate once at the flowering and pod stage, water until the soil moisture content is maintained at...

Embodiment 2

[0077] Select Huangmian land with deep soil, flat terrain, loose soil, and convenient irrigation and drainage to carry out deep plowing before transplanting Astragalus, the depth is 35cm, and apply commercial organic fertilizer 2800kg hm -2 And biological fertilizer 650kg·hm -2 Combined application of ternary compound fertilizer 700kg·hm -2 , shovel off the surface soil to make the ground level; plant Astragalus membranaceus on April 15, adopt the open-field ditch planting method, and ditch the flattened plot, the depth of the planting ditch is 30cm, and place the seedlings flat or inclined in the ditch Cover and plant seedlings while turning the soil, the planting spacing is 16cm, the row spacing is 25cm, the seedlings are covered with soil, so that the seedlings are covered with soil 3cm, and the seedling capacity is 280,000 plants / hm 2 ; Irrigate 2 times at the flowering and pod setting stage, water until the soil moisture content is kept at 80%, and topdress N fertilizer ...

experiment example

[0083] From 2019 to 2020, experiments were conducted on the plots of Chen Jigang, a farmer in Xiaolin Village, Lujing Town, Minxian County, and the Linong Chinese Medicinal Planting Cooperative in Zana Village, Qinxu Township. Astragalus seedlings are purchased locally, and the variety of pine cauliflower is Fusong 100.

[0084] The test adopts a single-factor test plan, and two treatments are set up in Examples 1-2, the rotation of pine cauliflower and Astragalus membranaceus, and the continuous cropping of Astragalus membranaceus in Comparative Example 1, and the continuous cropping treatment is used as the control. Randomized block design, the experimental field is divided into 3 blocks, the block length is 8m, and the width is 7m. Make the same block group be on the same slope, design two plots for each block group, the plot area is 28m 2 (4m×7m). In 2019, astragalus will be planted, and in 2020, pine cauliflower and astragalus will be planted in the plots of Astragalus ...

Abstract

The invention provides a cultivation method for crop rotation of astragalus membranaceus and cauliflower, and relates to the technical field of crop cultivation, the cultivation method for crop rotation of astragalus membranaceus and cauliflower comprises the following steps: planting astragalus membranaceus from March 15 to April 15, and harvesting astragalus membranaceus from October 15 to November 15 in the same year; planting the brassica oleracea from May 1st to May 15th in the next year, and harvesting after the brassica oleracea is mature; the problem of traditional continuous cropping obstacles of the astragalus membranaceus is solved, the yield of the astragalus membranaceus is increased, and meanwhile the quality of the astragalus membranaceus is improved; and the yield of the astragalus membranaceus planting industry is improved by crop rotation with the brassica oleracea.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cultivation method for rotation of astragalus and pine cauliflower. Background technique [0002] Astragalus is one of the most widely used traditional Chinese medicines in clinical prescriptions and Chinese patent medicines. It is known as "ten medicines and eight qi" in the pharmaceutical industry, and it is also a Chinese medicinal material with a large export volume. Astragalus is planted in a large area in Dingxi, Gansu Province. However, due to the influence of arable land area and market demand, Astragalus has encountered continuous cropping obstacles. Continuous cropping or crop rotation with food crops are often used in actual fields, resulting in reduced yield and quality of Astragalus membranaceus, and root rot is becoming more and more serious, leading to a decline in market prices and reduced income. According to the survey, the prevalence of Astragalus me...
