Embodiment 1

[0025] Embodiment 1: alternative plant ecological adaptability test

[0026] Substitute plants for the test are: kudzu vine (cultivated species: Jingxi kudzu, provided by Beijing Sanfa Plant Seedling Research Center), African foxtail, pig dung bean, thatched grass, corymbose cassia, perennial ryegrass, duck grass, wolf's tail Grass, 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. The month is rainy, and the drought is severe from August to October.

[0027] The experimental site is an abandoned mountainous area with a slope of 2...

Embodiment 2

[0041] Embodiment 2: field test of alternative plant control Eupatorium adenophorum

[0042] 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 is reddish-yellow soil with an organic matter content of 27.2-32.3g / Kg. The soil is barren and sticky. In 2011, the drought was severe from May to June in the year of planting; the next year was rainy during the growth period, and there was no severe drought. The experimental site is a gentle hillside with a slope of 20°. Before planting Pueraria adenophorum, the Eupatoria adenophorum was cut off from the ground, and then the roots of Eupatoria adenophorum were thoroughly excavated, and then Pueraria adenophorum was transplanted or cut on May 3, 2011. The ways of growing kudzu greenhouse seedlings and transplanting with soil are the same as in Example 1; the cutting meth...

Abstract

The invention discloses a method for replacement control of Eupatorium adenophorum Sprengel by using Pueraria spp., belonging to the field of replacement plants. According to the method for replacement control of Eupatorium adenophorum Sprengel by using the Pueraria spp., steps of breeding seedlings of Pueraria spp., transplanting, weeding in proper time, fertilizing in a targeted manner, etc., are implemented on land, where Eupatorium adenophorum Sprengel grows, in the south of China, to replace the Eupatorium adenophorum Sprengel by the Pueraria spp., and therefore, a benign successional ecological community is established. The Pueraria spp., which has the features of rapid growth speed, high coverage degree, perennial property and good effect of replacement control over the Eupatorium adenophorum Sprengel, can be used as an economic crop, a feed crop and a medical material.

Description

technical field [0001] The invention belongs to the field of substitute plants, and in particular relates to a method for controlling Eupatoria adenophorum by using kudzu vines instead. 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 appropriately. Eupatorium adenophorum can adapt to occur and grow in a wide...
