Description

Multifunctional orchard weeding vegetation blanket based on dynamic response gel Technical Field The invention relates to the technical field of agricultural weeding, in particular to a multifunctional orchard weeding vegetation blanket based on dynamic response gel. Background Orchard weeds are a great difficulty in the production of the planting industry, restrict the economic sustainable healthy development of fruit trees, have great harm to the production of the orchard, and become a main factor restricting the growth of the fruit trees and the quality of fruits. At present, the main methods for removing weeds include cultivation weeding, chemical weeding, plastic film mulching, weed mulching and the like. The cultivation weeding has large dependency on the instrument and the labor cost, and obvious games exist among the soil turning depth, the weeding force and the root protection of the fruit tree, and as the weeds cannot be pulled up continuously, repeated operation is needed for many times. The chemical weeding can eradicate annual and perennial weeds, reduces the manual investment, can avoid damaging the root systems of the surface fruit trees, and can not reduce the absorption of the fruit trees to nutrient substances, but the chemical prevention and removal measures have shorter efficacy period, and the high-frequency use can cause serious damage to the fruit trees, soil environment and orchard ecology. The artificial grass growing cover mainly forms a shading space with high density on the surface of soil of an orchard by planting specific grass plants, so that weeds cannot grow normally, the grass controlling effect is achieved, and the grass growing cover is an advanced and ecological environment-friendly weeding mode, but weeds in the orchard have extremely strong vitality, and the grass growing is difficult to take advantage in a short period. The plant blanket is used for weeding, and the plant blanket is covered on the soil surface to form a plant covering layer to prevent photosynthesis of weeds, so that the growth of the weeds is prevented, and the competition of the weeds to plants is reduced. In addition, in practical situations, the environment may not be even, for example, the vegetation blanket is paved under the environmental conditions of furrows, the grass seeds may be washed and shifted under the external environment, for example, the condition of strong wind and heavy rain, the phenomenon of uneven grass emergence is caused, weeds grow in places without grass emergence, and the grass inhibition effect is affected, and the weeding efficiency is reduced. Therefore, how to stabilize the positions of grass seeds and improve the weeding efficiency while achieving the purpose of suppressing grass quickly is an urgent need at present. Disclosure of Invention In view of the above, the invention aims to provide a multifunctional orchard weeding vegetation blanket based on dynamic response gel, which solves the problems of uneven grass emergence and poor weeding capability of the vegetation blanket. The invention solves the technical problems by the following technical means: The multifunctional orchard weeding vegetation blanket based on dynamic response gel comprises a fixing layer, a covering loose layer, a vegetation layer, a nutrient storage layer, an isolation layer and an pocket bottom layer from top to bottom, wherein the vegetation blanket is sequentially paved and then sequentially inserted and fixed from top to bottom by a puncture machine, the fixing layer and the pocket bottom layer are warp and weft nets woven by polyethylene materials, the covering loose layer is made of coconut fibers, the vegetation layer is made of stable gel, grass seeds, organic fertilizers and coconut fibers in a mixed mode, the nutrient storage layer is made of coconut fibers and organic fertilizers in a mixed mode, and the isolation layer is made of polypropylene fiber cloth. Further, the using method of the vegetation blanket comprises the following steps: (1) Removing weeds, foreign matters and broken stones on the slope surfaces of the furrows, and paving plant-growing carpets according to different grass seed requirements on the furrows; (2) When the vegetation carpets are paved, the vegetation carpets should be fully contacted with soil and soil Dan Pomian, after each vegetation carpet is paved, U-shaped iron nails are adopted to be fixed in a staggered way according to the interval of 1m-1.5m, two adjacent vegetation carpets are lapped, and the periphery of each vegetation carpet is fixed by ditching; (3) After the vegetation blanket is laid, the surface of the vegetation blanket is evenly covered with soil for 2-3cm by adopting manpower or machinery, the soil is covered and flattened and rolled to enable the vegetation blanket to be fully combined with the soil, and then sodium bicarbonate solution with the pH of 7.5-8 is sprayed on the surface of the vegetation blanket once, wherein the spr
