Description
Technical Field
[0001] The invention relates to the technical field of soil and water conservation, and in particular to a sand-fixing straw mat woven with plant seedlings and a manufacturing method thereof. Background Art
[0002] Land desertification is caused by unreasonable human activities on the fragile ecological environment, which is mainly manifested in the decline of land productivity, the loss of land resource functions, and the land degradation of the desert landscape. As one of the countries in the world with the largest desert area, the wide distribution, and the serious harm of desertification, the rate of land desertification in my country is accelerating and expanding. Therefore, how to effectively prevent grassland desertification is a difficult problem that needs to be solved urgently.
[0003] According to current experiments, using grass sand barriers to fix sand has achieved remarkable results in desert control. However, sand fixation alone cannot completely solve the problem of land desertification. The desertified land also needs to be covered with green. In order to increase the vegetation coverage rate, the traditional practice is to sow grass seeds or transplant seedlings in the grass grids. However, whether it is manual or mechanical sowing, it will cause damage to the grass sand barrier. After sowing, the grass sand barrier needs to be repaired again. In the process of repairing the grass sand barrier, the planted plants are once again destroyed. The repeated cycle is labor-intensive and time-consuming, and the greening effect is poor. Summary of the invention

[0011] S5. Bury one side of the straw mat seedlings in the sand and keep the roots of the seedlings 5-8cm below the ground. Water them 1-2 times in time.
[0012] Moreover, in step S4, a rope on one side of the straw mat for weaving seedlings is woven from two strands of seed rope and traditional rope, and is flush with the ground or buried 0.5-1 cm shallowly; the method for making the seed rope is as follows:
[0013] (1) Coating the selected seeds with a drug that repels animals and insects and then drying them;
[0014] (2) Fix the coated seeds on the planting paper;
[0015] (3) Cut the planting paper with seeds fixed on it into strips with a width of 5-10 cm, twist the strips into ropes, and roll them up to make seed ropes.
[0016] Furthermore, the agent for driving away animals and insects is a rodent repellent, a bird repellent, a rabbit repellent and an insect repellent;
[0017] The method of seed coating is: soaking the seeds in a potion prepared with a medicine for repelling animals and insects or stirring the seeds in a wet powder prepared.
[0018] Moreover, the method for fixing the seeds on the planting paper is: mixing coated seeds into the pulp for producing the planting paper or fixing the seeds on the planting paper with an adhesive, wherein the adhesive is cellulose;
[0019] The amount of coated seeds fixed on the planting paper is: 30-50 seeds per meter for herbaceous seeds and 10-15 seeds per meter for woody seeds.
[0020] Moreover, the medicament for repelling animals and insects is wood vinegar, MA crude oil, MP crude oil.
[0021] Moreover, the rope is a rope made of traditional braided rope.
[0022] Moreover, the water retaining agent is a highly absorbent resin with a concentration of 1‰, and the soaking time is 1-2 hours.
[0023] Moreover, when the seed rope is used as a rope, the density of weaving seedlings is 1.5-2m per one.
[0024] Moreover, when the traditional rope is used as a rope, the density of the braided seedlings is 1-1.5m per tree.
[0025] Moreover, sand-fixing straw mats are laid in the Ulan Buh Desert, and the seeds are shrub seeds and ground cover seeds; the shrub seeds are Artemisia selengensis and Caragana pheasant; the ground cover seeds are Artemisia sphaerocephala, Artemisia ordosica, Stipa psora and Psoralea corylifolia, and the seedlings are shrub or tree seedlings.

The present invention sows plant seeds or transplants saplings while laying the grass sand barrier, thus avoiding damage to the laid sand barrier by secondary operations and also avoiding damage to plants by secondary repair. It can survive in one go, save time and energy, improve work efficiency, and facilitate promotion.
[0029] 3. The present invention uses a drug for driving away animals and insects to coat the selected seeds when making seed ropes, thereby preventing them from being eaten by birds, mice, rabbits and insects, thereby improving the seed utilization rate and further improving the germination rate.
[0030] 4. The present invention provides plants suitable for use as vegetation curtains and sand barriers in the Ulan Buh Desert region. The seeds have strong adaptability to the region, and the plant survival rate can still reach 70% despite the strong winds and little rain in the Ulan Buh Desert region.
[0031] 5. The grass-sand barrier can prevent the wind from blowing away the snow and hinder the flow of water. The snow and rainwater concentrated near the grass-sand barrier and the moisture absorbed into the grass-sand barrier can provide moisture conditions for the germination and growth of seeds or seedlings in the grass-sand barrier, thereby ensuring the survival of the seeds or seedlings.

[0125] Comparative Example 1
[0126] This comparative example is the same as Example 3 except that no coating treatment is performed, and its emergence rate is measured.
[0127] Comparative Example 2
[0128] This comparative example is the same as Example 3 except that the density of weaving seedlings is 2.5 m per plant, and the emergence rate, emergence rate and survival rate are determined.
[0129] Comparative Example 3
[0130] This comparative example is the same as Example 3 except that the density of weaving seedlings is one seedling per 1 m, and the emergence rate, emergence rate and survival rate are determined.
[0131] Comparative Example 4
[0132] This comparative example is the same as Example 6 except that the straw mat is buried in the sand so that the root of the seedling is 4 cm below the ground, and the survival rate is measured.
[0133] Comparative Example 5
[0134] This comparative example is the same as Example 6 except that the straw mat is buried in the sand and the root of the seedling is 9 cm below the ground, and the survival rate is measured.
[0135] Comparative Example 6
[0136] This comparative example is the same as Example 6 except that the density of weaving seedlings is 0.5m per plant, and the survival rate is measured.
[0137] Comparative Example 7
[0138] This comparative example is the same as Example 6 except that the density of weaving seedlings is 2 m per seedling, and the survival rate is measured.
[0139]
[0140] It can be seen from Table 1 that in Example 1, no coating was performed, and the emergence rate and survival rate were only 16.4% and 15.9% respectively. In Example 3, the seedling weaving distance was too close, which affected the water absorption and the survival rate decreased. In Examples 4 and 5, the burial depth was too deep or too shallow, which also affected the survival rate of the plants.
[0141] Experimental Section
[0142] Three observation points were selected in the straw mat area and set as four observation groups. The moisture content of the soil at the straw mat and at 10 cm, 20 cm, 30 cm, 40 cm, 50 cm and 60 cm away from the straw mat was measured respectively. The specific experimental data are shown in Table 2 below.
[0143]
[0144] It can be seen from Table 2 that the closer to the straw curtain, the higher the soil moisture content. This is because, after snowing in winter, the straw curtain can prevent the wind from blowing away the snow; after raining in summer, the straw curtain can prevent the loss of rainwater; at the same time, the straw curtain itself will absorb some moisture, and the snow and rainwater concentrated near the straw curtain and the moisture absorbed into the straw curtain can provide moisture conditions for the seeds and seedlings in the straw curtain to germinate and grow. The closer to the straw curtain, the greater the change in moisture content, and after a distance of 40 cm, the impact will not be very obvious. It can be proved that the sand-fixing straw curtain of the present invention has a significant effect on the moisture content of the desert, and therefore affects the emergence rate of plants.
