Problems solved by technology

The effect of chemical herbicide is stable and the control effect is high. However, the technical requirements for the use of herbicides are strict, and it is easy to cause phytotoxicity to crops. The residues in the soil cause environmental pollution and destroy the ecological balance. They are also easy to residues in agricultural products, causing food safety.
Manual weeding is labor-intensive and costly, and is no longer suitable for the current national conditions of shortage of labor resources and aging labor force in our country
Although mechanical weeding is good, there are few weeding machines for specific crops, and many crop fields do not have usable machines
Agricultural measures alone cannot completely solve weed problem

Embodiment 1

[0012] Example 1 The effect of broccoli pollen on the germination and growth of several weed seeds

[0013] Wash the fresh broccoli with tap water, let it dry naturally in the room, grind the whole plant into powder with a pulverizer, take 0.5g, 0.6g, 0.7g, 1.0g, and 1.5g of broccoli pollen and put them into petri dishes respectively (d=9cm), pour 10mL of distilled water, cover 2 layers of filter paper on the broccoli pollen, take 20 weed seeds and put them on the filter paper, set 3 times of repetition, take no broccoli pollen as the control, at 25℃ The light and dark were alternately cultivated for 12 hours, and the germination and growth of weed seeds were investigated after 7 days of cultivation, and the germination rate and germination inhibition rate of the seeds were calculated.

[0014] Germination rate = number of weed seeds germinated / total number of weed seeds × 100%

[0015] Germination inhibition rate=(control group emergence number-treatment group emergence numb...

Embodiment 2

[0019] Example 2 Control effect test of broccoli pollen potted plants

[0020] Take topsoil from the farm of Inner Mongolia Agricultural University, put it into flower pots, and use 13g / m 2 Sprinkle the broccoli pollen on the surface of the flower pot, take no broccoli pollen as the control, water it quantitatively, and observe the inhibitory effect of the broccoli pollen on the germination and growth of weeds after 7 days.

[0021] The results showed that the germination amount of weeds treated with broccoli pollen was significantly less than that without treatment, the germination inhibition rate of broccoli pollen to gramineous weeds was 96.1%, the germination inhibition rate of broad-leaved grass was 92.8%, and the germination inhibition rate of broccoli pollen was 92.8%. The germination inhibition rate of grass is 94.5% (table 2, figure 2 ).

Embodiment 3

[0024] Embodiment 3 field control effect test

[0025] The field control effect test was carried out in 2016. It was located in Xiyongle Village, Daihai Town, Liangcheng County, Inner Mongolia. Broccoli was planted in the field, and the cultivated land was 30cm in autumn. The emergence of weeds was investigated on May 17 in the spring of the following year. control.

[0026] The results showed (Table 3, image 3 ), the main weed emerging from the field is quinoa, the plots planted with broccoli have fewer and smaller weeds, and the plots planted with potatoes have many and larger weeds, and every 0.25m 2 There were 38.5 more potato plots than broccoli, which can significantly inhibit the germination and growth of quinoa.

Abstract

The invention discloses application of broccoli to inhibiting of weed germination and growth, and belongs to the technical field of weeding. The seed germination inhibition rate of the broccoli to weed of Chenopodium album, Artemisia hedinii, Setaria viridis (L.) Beauv. var. gigantea, Chloris virgata and Panicum miliaceum can reach 98%, 100%, 98%, 97%, 98%. Through a potting effect control test, the result shows that the weed germination inhibition rate of the broccoli reaches 94.5%. In a field test, the broccoli can significantly inhibit germination and growth of the Chenopodium album. The broccoli is applied to the technical field of weeding, the advantage of high efficiency, safety, environmental protection and the like are achieved, and development and application prospects are wide.

Description

technical field [0001] The invention belongs to the technical field of weeding, and relates to the application of broccoli in inhibiting the germination and growth of weeds. Background technique [0002] Weeds in farmland are the main factor leading to the reduction of crop yield. They compete with crops for water, fertilizer, light energy, etc., reduce crop yield and variety, and affect crop harvesting and threshing. Safe and efficient control of weeds has become the core content of agriculture. The current methods of controlling weeds mainly include chemical, artificial, mechanical, agricultural and ecological weeding and other measures. Chemical herbicides have stable effects and high control efficiency, but herbicides use strict technical requirements, which can easily cause phytotoxicity to crops, and residues in the soil can cause environmental pollution and disrupt ecological balance, and residues in agricultural products can easily cause food safety. Manual weeding...
