Te present invention discloses a cultivation method for improving quality and yield of lepidium meyenii walpers. The method comprises the following steps of: (1) cultivated land selection; (2) seed seedling; (3) transplantation and planting; (4) defect checking and seedling filling; (5) field management; and (6) seed reservation. Through seed pelleting, the insect pests of lepidium meyenii walpersseeds suffered in the growth process can be prevented such as aphids and cutworms; the usage of the bacterial manure improves the soil microorganism system, reduces soil hardening and solidification,enhances soil fertility and provides adequate nitrogen fertilizer for plant growth, the bacterial strains in the bacterial manure can secrete auxin (IAA) and jasmonic acid methyl ester (MeJA), the IAA promotes growth and development of the lepidium meyenii walpers, the MeJA can induce the chemical defense of the plants so as to reduce the diseases and insect pests. The quality and yield of lepidium meyenii walpers can be greatly improved, the content of lepidium meyenii walpers under the cultivation of the bacterial manure is larger than the content of the macamides and macaenes under commoncultivation, and the fresh weight of a single plant and a diameter of a root are larger than these under common cultivation.

The invention discloses a composite fluororubber adhesive plaster and a preparation method thereof, belonging to the technical field of chemical defense. The composite fluororubber adhesive plaster takes 507 brocade silk as a basic cloth material and takes the basic cloth material of which the two surfaces are coated with an anti-flaming chlorinated butyl adhesive layer respectively as a main body cloth. The front surface of the main body cloth is coated with a fluororubber layer. In the preparation process, both surfaces of the 507 brocade silk are soaked with a chloroprene rubber adhesive; an anti-flaming chlorinated butyl adhesive is stirred with 120# gasoline at a mass ratio of 1 to 1.5 so as to obtain adhesive cement, and the adhesive cement is coated on the both surfaces of the 507 brocade silk; fluororubber is stirred with acetic ether at a mass ratio of 1 to 2 so as to obtain adhesive cement, and the adhesive cement is coated on the front surface of the adhesive plaster; and a finished product is obtained by primary drum or tank type vulcanization and secondary tank type vulcanization. The composite adhesive plaster disclosed by the invention has a stronger protection property to gas matters and a very strong anti-corrosion property to organic solvents, and has the advantages of good physical and mechanical properties, low price, simple preparation method and very high market value.
