Problems solved by technology

[0010] The purpose of the present invention is to provide a method of using the perennial dicotyledonous plant Amorpha amorpha with strong stress resistance to replace and control Eupatorium adenophorum, which can not only solve the problem that annual dicotyledonous plants cannot be continuously replaced, but also solve the problem of some perennial dicotyledonous plants. Dicotyledonous plants cannot adapt to the problem of poor and sticky soil, and at the same time, it can solve the problem that the grass substitute plants are too closely related to the associated grass weeds and it is difficult to find a safe herbicide, which is beneficial to the alternative control of grasses. Chemical control of undergraduate weeds to avoid labor-intensive weeding at the initial stage of planting

Embodiment 1

[0022] Embodiment 1: alternative plant ecological adaptability test

[0023] The substituted plants for the test were Amorpha fruticosa (provided by Beijing Millennium Dadi Grass Ecological Technology Development Co., Ltd.), broad-leaf paspalum, African foxtail, pig dung bean, thatched cottage, corymbose cassia, perennial ryegrass, duckweed, Pennisetum, car mulberries. The test was carried out in Chitu Village, Huishui County, Guizhou Province. The test site is located at 26.2° north latitude, 106.3° east longitude, and an altitude of about 1000m. The frost-free period is about 270 days. The annual average temperature is 14-16°C. The monthly average temperature is 4-6°C, the annual extreme maximum temperature is between 34.0-36.0°C, the extreme minimum temperature is between -6.0--9.0°C, and the annual average annual precipitation is 1100-1300mm. It is rainy, and the drought is severe from August to October.

Embodiment 2

[0031] Example 2: Field test of Amorpha fruticosa controlling Eupatoria adenophorum

[0032] The test was carried out in Shazi Township, Zhenning County, Guizhou Province, about 100Km away from the site of Example 1, and to the southwest. The climate and altitude are similar to the Huishui test site, the soil organic matter content is 27.2-32.3g / Kg, and the soil is barren and sticky. In 2010, the year of sowing and the second year of growth were severely drought in May-June; the third year of growth was rainy and there was no severe drought.

[0033] The experimental site is a gentle slope mountain with a slope of 20°, and a small number of young peach trees are planted, with a density of 1 tree / 43.5m 2 , canopy density is less than 0.69. The number of Eupatorium adenophorum before site preparation (division number) was 71.7 plants / m 2 . The sowing time was May 1, 2010, when the soil moisture was good. First cut off Eupatorium adenophorum evenly on the ground, and then co...

Abstract

The invention discloses a method for replacement control of Eupatorium adenophorum Sprengel by using Amorpha fruticosa L. in the field of biological prevention and control. The method is used for replacing the Eupatorium adenophorum Sprengel by using the Amorpha fruticosa L. to construct an ecological community with a positive succession function through steps of seeding the Amorpha fruticosa L., removing weed at proper time, conducting targeted fertilization and the like on land which is full of the Eupatorium adenophorum Sprengel. Two years later after the Amorpha fruticosa L. is seeded, the growth speed is accelerated, a good effect of replacing and controlling the Eupatorium adenophorum Sprengel is taken, soil fertility can be improved and the Amorpha fruticosa L. can be used as plants with economic use values.

Description

technical field [0001] The invention belongs to the field of biological control, and in particular relates to a method for substituting and controlling Eupatoria adenophorum by using amorpha amorpha. Background technique [0002] Eupatorium adenophorum (Eupatorium adenophorum Sprengel), Eupatorium adenophorum genus, Asteraceae Eupatorium genus, perennial herb or subshrub, seed propagation and vegetative propagation, seeds are extremely small, 1000-grain weight 0.04-0.045g, each Eupatorium adenophorum can produce 3-10 seeds Thousands of grains, spread by wind, water or carry. Eupatorium adenophorum can be grown under climate conditions where the annual average temperature is higher than 10°C, the annual average relative humidity is higher than 68%, the absolute minimum temperature is not lower than -11.5°C, the highest temperature is below 35°C, and the coldest monthly average temperature is higher than 6°C. grow properly. Eupatorium adenophorum can adapt to occur and grow ...
