Embodiment 1
[0031] Embodiment 1: Optimum test of silk leaf leek seed treatment method
[0032] In mid-May 2017, the seeds of Chinese chives harvested in October 2016 were used as the test material. By comparing the germination of the seeds after different chemical treatments, the optimal chemical reagents and treatment methods were selected, and the seeds were first soaked with different chemicals, and then the germination test was carried out. , specifically the following schemes:
[0033] Treatment experiment design is: 1, with concentrated H 2 SO 4 Germinate after soaking for 5 minutes. 2. After soaking the seeds in 30% polyethylene glycol solution for 10 hours, conduct a germination test to accelerate germination. 3. After soaking the seeds in 30% polyethylene glycol solution + 5% gibberellin·indole acetic acid solution for 10 hours, conduct a germination test to accelerate germination. 4. After plasma treatment by the plasma seed treatment machine, let it stand in the dark room f...
Embodiment 2
[0037] Embodiment 2: Cultivation test of colorful potato and Chinese chives in large field
[0038] From October 2016 to October 2017, the research team conducted large-scale field cultivation experiments of colored potatoes and silk-leaved leeks in the film-covered potato planting area of Shiba Township, Wuyuan County, Bayannur City, Inner Mongolia. The climate in this area belongs to the mid-temperate continental climate. It has the characteristics of rich light energy, sufficient sunshine, dry and windy, and low rainfall. The average annual rainfall is 170mm, and most of it is concentrated in summer and autumn, which is more consistent with the water demand period of potatoes; the local high-yield colorful potato variety H-Black Beauty is selected As a test variety; the specific implementation plan is as follows:
[0039] (1) Land selection and land preparation: select the flat land where the previous crop is corn, perform deep plowing after autumn harvest, and wait for s...
Embodiment 3
[0045] Embodiment 3: Field single-cropping color potato test
[0046] From October 2016 to October 2017, the research team conducted field monoculture color potato cultivation experiments in the film-covered potato planting area of Shiba Township, Wuyuan County, Bayannaoer City, Inner Mongolia. Rich, abundant sunshine, dry and windy, and low rainfall. The average annual rainfall is 170mm, and most of them are concentrated in summer and autumn, which is more consistent with the water demand period of potatoes. The local high-yield colorful potato variety H-Black Beauty was selected as the experimental variety ; The specific implementation plan is as follows:
[0047] (1) Same as embodiment 2;
[0048] (2) Seed treatment: 5 days before sowing, cut potato seed potatoes for seed dressing; the specific steps for the treatment of colored potato seed potatoes are: (1) Optimal seed potato cutting: about 5 days before sowing, select high-quality Cut the seed potato into pieces. Whe...
