Embodiment 1

[0093] Embodiment 1. The prevention and treatment of the freezing damage of medicinal plant (lycium barbarum) and the damage of caterpillar fungus

[0094] Experimental site: Lycium barbarum garden in the 10-year fruiting period, the spacing between plants and rows is 1.2m×3.0m, under conventional management, the occurrence of red gall midges is relatively heavy, and the total area is about 2000m 2 . The experimental site is divided into two experimental groups, each 1000m 2 , level the land before processing.

[0095] 1. Control method (film mulching treatment):

[0096] Using commercial PVC agricultural film ("Tianzijiao" brand, produced by Changzhou Tianzijiao Plastic Products Co., Ltd., thickness 0.01mm), according to the method of CN200610153302.8 public specification (page 2, line 7-19), in April 2013 Carry out coating treatment on the 5th.

[0097] The specific method is: take the tree as the center line, and cover PVC agricultural film on both sides of the tree row...

Embodiment 2

[0130] Embodiment 2: the control of diseases, insects and weeds of medicinal plants (chrysanthemum)

[0131] Experimental site: In April 2013, a control experiment of composite woven geotextiles was carried out in a chrysanthemum planting base in Jining, Shandong, with an area of ​​6 mu. On April 10th, fully fermented organic fertilizer was evenly spread, and the amount of fertilizer applied was 5m 3 / mu; Rotary tillage was carried out on April 11, and then the rotary plow was used to harrow it, and the ground was lined to determine the planting point. The row spacing between plants and rows was 60cm×100cm, and the planting land was ready. Transplant the chrysanthemum seedlings on April 15, and immediately water the planting hole after transplanting, with about 1000ml of water per plant. On April 16, the entire chrysanthemum garden was covered. Among them, 4 mu of chrysanthemum gardens adopt the application method and the described composite woven geotextile, and the other ...

Embodiment 3

[0167] Embodiment 3: the prevention and treatment of freezing damage of fruit tree (alpricot tree) and insect pest

[0168] Plants that bloom in early spring, such as apricot, peach, plum, and pear, bloom too early and are vulnerable to the threat of late frost in spring, resulting in reduced production or even extinction. Schisandra chinensis and other Chinese medicinal materials, in the process of artificial domestication and cultivation, often lead to reduced production or even extinction due to late frost. Preventing late frost is an urgent problem to be solved in agricultural production.

[0169] Experimental site: The apricot tree experiment was carried out in March 2013 in three adjacent 10-year-old apricot orchards in Yongning County, Ningxia Hui Autonomous Region. The apricot tree variety is Kate apricot. 3 apricot orchards are adjacent to each other, about 300-700 meters apart, one of which has an area of ​​about 2000m 2 , the other two are about 1500m 2 , the sp...

Abstract

The invention relates to a product for preventing plants from freezing damage and pests and weeds and use of the product. The product disclosed by the invention is double-layer composite woven geotextile made from a woven layer and a fiber layer. After the composite woven geotextile is laid on a plant planting field, the germination time for the plants can be effectively retarded, so that the plants can evade a freezing damage period, and meanwhile, the damage causing period of the pests can be non-synchronous to the growing period of the plants. The composite woven geotextile disclosed by the invention can also be used for effectively preventing the damage caused by the pests, preventing the damage caused by the weeds and maintaining soil tilth.

Description

technical field [0001] The present disclosure relates to the field of agriculture; in particular, to articles for preventing frost damage, insect damage, and weeds, as well as uses and methods thereof. Background technique [0002] The freezing damage of crops often affects agricultural production. In recent years, there have been frequent reports in this regard. [0003] On April 13, 2006, apricot and plum trees in full bloom suffered severe frost damage, among which 160,000 mu of apricot trees in Pengyang County suffered severe frost damage. In the spring of 2013, the temperature was on the high side, which made the apricot, peach, and pear trees germinate 1-2 weeks in advance. They bloomed in early April, and low-temperature frost appeared from April 6 to 9. The apricot, plum, and mountain peach trees almost Extinct production (Ningxia Agriculture and Forestry Science and Technology, No. 3, 2010, Yang Zhengde, Investigation and Analysis of Freezing Damage of Apricot Tre...
