Description
Technical Field
The invention relates to the technical field of weed prevention and control, and particularly relates to a matrix for preventing and controlling farmland weeds and a prevention and control method thereof.
Background
Farmland weeds refer to plants that grow on areas that are harmful to human survival and activity, typically non-cultivated wild plants or plants that are harmful to humans. Weeds in farmlands have certain harm, for example, the weeds compete for nutrients, moisture, sunlight and space with crops, ventilation and light transmission in the farmlands are prevented, local climate temperature is increased, and some weeds are intermediate hosts of diseases and pests to promote the occurrence of diseases and pests; parasitic weeds absorb nutrients directly from the crop, thereby reducing the yield and quality of the crop. In addition, some weed seeds or pollen contain toxins, which can poison people and livestock.
At present, manual weeding and weeding with simple farm implements are the most applied, but the method has the defects of high labor consumption, low efficacy and incapability of preventing and removing weeds in a large area in time. In addition, mechanical weeding is also carried out, namely, weeding machines drawn by animal power or mechanical force are used for mechanically cultivating, harrowing and covering soil so as to control the occurrence and harm of farmland weeds. However, frequent use thereof causes hardening of the plough layer soil. Chemical weeding is the removal of weeds with herbicides without damaging the crop. When the herbicide is used, the weed can be controlled by utilizing the type of the herbicide and the action principle on plants according to the growth characteristics and rules of crops and weeds. The chemical treatment can be further divided into soil treatment and stem leaf treatment, wherein the soil treatment is to spray a medicament on the surface layer of the soil or mix the medicament into the soil through soil mixing to form a closed medicament soil layer, so that weeds can not normally emerge or die. The soil treatment can be divided into pre-sowing treatment, post-sowing pre-emergence treatment and post-emergence treatment according to the treatment time. The stem and leaf treatment is usually carried out by spraying a herbicide on the stems and leaves of the weeds after the weeds grow on the surface of the soil, and the weeds are killed by the absorbing agent of the leaves or the contact of the stems and the leaves with the agent. The method can be divided into stem and leaf treatment before sowing and stem and leaf treatment after sowing in growth period according to the spraying time period. Chemical weeding methods can save a large amount of manpower and material resources, but easily induce a series of problems such as herbicide resistance, pesticide residues, and harm to non-weed organisms (particularly human and livestock). Therefore, the selection of safe means of weeding is a key issue in weed control.
The edible fungus refers to edible fungus with large fruiting body. The edible fungi are rich in protein and amino acid, and have certain health promotion effects, such as promoting digestion, lowering blood pressure, etc. With the development of the edible fungus industry in recent years, a large amount of edible fungus waste materials are generated in the edible fungus production area every year, if the edible fungus waste materials are not properly treated, not only is the resources seriously wasted, but also the environment is greatly harmed, and the spreading of plant diseases and insect pests is caused. In order to improve the utilization rate of edible fungus waste, CN113209144A discloses a method for extracting mushroom dregs, a mushroom dreg extract and application. CN108002541A discloses a decolorizer containing Pleurotus citrinopileatus mushroom dreg extract, which is prepared by extracting Pleurotus citrinopileatus mushroom dreg with citric acid buffer solution, removing the extractive solution to obtain dreg residue for inoculating Pleurotus ostreatus strain, fermenting and culturing, and extracting the mixed product of culture medium and mycelium with citric acid buffer solution to obtain the decolorizer. In addition, researchers can also use the mushroom dregs as fuel after drying the mushroom dregs in the sun or directly use the mushroom dregs as feed after crushing the mushroom dregs. However, the research of directly applying the mushroom dreg waste to farmland weeding is only reported. Based on the method, the invention provides a farmland weed prevention and control method to reduce the application of the herbicide, thereby reducing the harm of the herbicide.
Disclosure of Invention
Aiming at the problems, the invention provides a farmland weed prevention and control substrate and a farmland weed prevention and control method thereof.
The first object of the present invention is to provide a substrate for controlling weeds in agricultural fields, which is used for controlling weeds during the growth of crops;
the matrix for preventing and controlling the farmland weeds consists of bacterial residues, peat soil and phosphate, wherein the mass ratio of the bacterial residues to the peat soil to the phosphate is 1:2-3.
Preferably, the mass ratio of the mushroom dregs, the peat soil and the phosphate is 1.
Preferably, the mushroom dregs are one or more of needle mushroom dregs, oyster mushroom dregs, pleurotus eryngii dregs and seafood mushroom dregs.
Preferably, the phosphate is one of sodium dihydrogen phosphate, disodium hydrogen phosphate and calcium dihydrogen phosphate.
Preferably, the crop is a solanaceous vegetable.
Preferably, the weeds are grasses and broadleaf weeds.
Preferably, grassy weeds include, but are not limited to, goosegrass, alopecurus, crab grass, moleplant, green bristlegrass, barnyard grass; broad-leaved weeds include, but are not limited to, amaranth, ma Songzi, polygonum cuspidatum, annual fleabane, atriplex canescens.
The second purpose of the invention is to provide a farmland weed prevention and control method, which comprises the following steps:
in the breeding period, after the crops germinate, the farmland weed control matrix is covered around the crops to inhibit the weeds from sprouting;
before the crops are transplanted, the farmland weed control matrix is covered on the soil surface to inhibit the weeds from sprouting, then planting pits are dug, and the crops are transplanted and fixed.
Preferably, the thickness of the substrate for controlling weeds in agricultural fields is 1 to 3cm
Compared with the prior art, the invention has the following beneficial effects:
compared with the prior art in which the fungus residues are extracted, the fungus residues, the peat soil and the phosphate are directly used, so that the operation steps are reduced, and the operation is simple and convenient. In the weed prevention and control process, the phosphate is matched with the fungus residue and the peat soil, so that the weed prevention and control effect is effectively promoted, and the use amount of the herbicide is reduced.
The matrix for preventing and controlling the farmland weeds has certain effect on both gramineous weeds and broadleaf weeds appearing in the planting process of solanaceae vegetables, and the effect of preventing and controlling the broadleaf weeds is higher than that of preventing and controlling the gramineous weeds due to strong vitality of the gramineous weeds.
