Abstract

The invention discloses application of switchgrass in desert control. Microsclerotia and mycelia adhering to the surfaces of seeds can be killed by adopting carbendazim spray; after seed dressing processing is performed with plant nutrients for herbal Chinese medicines, the seed germination rate and the plant weight and chlorophyll content of seedlings are improved, and therefore the yield of the swichgrass is improved; through the reasonable usage of a seed coating agent, pest and disease damage can be controlled on the condition that pesticide is not used, therefore, the switchgrass can be survived in desert and return green in the next year, plants on the ground can grow to 2 meters, and the underground roots can grow to 2 meters to well fix sand. The desert is controlled by adopting a sowing mode, labor input is reduced, and the effect that the switchgrass is planted and survived in the same year never achieves before; meanwhile, the switchgrass is good forage grass and is good feed of cows, horses and sheep and can continuously grow about 10 years.

Description

The application of switchgrass in control of desert

Technical field

The present invention relates to control of desert field, be specifically related to the application of switchgrass in control of desert.

Background technology

At present, desertization serious threat human survival, existing traditional administering method is difficult to large area, quick improvement alters the situation, tradition treatment cost is high, and government drops into huge fund every year, produces little effect, existing administering method has: beat motor-pumped well and to water greening, container band water, rubbish briquetting, (patent No.: 03109815.0), plants careless pill etc. and all exists and can only locally administer in transformation agent, simple function is administered, and affects the improvement of desert Environment.Therefore, sandstorm phenomenon, sand enters people and moves back phenomenon and drill more strict and more strict.

Summary of the invention

Switchgrass is the object of the invention is to be applied in control of desert aspect, switchgrass can survive in desert and can turn green by Second Year, plant can grow to 2 meters on the ground, underground root system can grow to 2 meters and well fix the sand, the mode of sowing is adopted to carry out Desert Control, reduce human input, plant success then then, have no precedent before.Switchgrass is good herbage simultaneously, is the feed of excellent oxen and horses sheep.

For achieving the above object, the present invention adopts following technical scheme:

The application of switchgrass in control of desert, comprises the steps:

S1, select high-quality switchgrass seed, except mould impurity elimination, adopt carbendazim spraying can kill bulbil and the mycelia of attachment the surface of the seed, after clear water washing, be placed in seed-soaking liquid, dipping 6h, described seed-soaking liquid by 0.1 part of MnSO4 powder, 0.05 part of CuSO4 powder, 0.12 part of ZnSO4 powder, 0.17 part of NiSO4 powder, 0.21 part of (NH4) 6Mo7024.4H20 powder and appropriate EDTA (preventing precipitation from generating), ionized water 300 ~ 400mL mixing gained;

S2, the seed after impregnation process to be pulled out, get appropriate nutrient for plants and carry out Dressing;

Described nutrient for plants comprises the medium trace element of 32 ~ 78% nucleosides hydrochlorates and 32 ~ 78%, obtain after described nucleosides hydrochlorate comprises ribonucleic acid basic hydrolysis: 5 '-adenylate dipotassium or sodium, 5 '-bird adenylate dipotassium or sodium, 5 '-cytidylic acid dipotassium or sodium, the potassium of 5 '-uridylic acid dipotassium or sodium four kinds of 5 '-mixed nucleotides or sodium salt, described medium trace element comprises Mn, B, Fe, Zn, Cu and Mo, and the weight ratio of described Mn: B: Fe: Zn: Cu: Mo is 5: 1: 3: 2: 3: 2;

S3, seed dressing is terminated after seed seed coat agent wrap up, the component of the following weight ratio of described seed coat agent is formed: lentinan 5.00%, Diacloden 3.00%, anticaking agent 2.5 ~ 3%, wetting agent 3 ~ 5%, emulsifier 2 ~ 2.5%, filler 1 ~ 2%, dyestuff 3 ~ 5%, water surplus;

S4, the annual early spring, by the seed of step S3 gained by every square metre of sub-30-40 gram of sowing, broadcast rear fine sand and cover, thick about 2.5 centimetres;

S5, sowed after, avoid unified after synoptic process irrigation, every 667m ²irrigation volume is 40m ³~ 60m ³;

S6, annual May and July every mu used 2.5 kilograms, nitrogenous fertilizer to irrigate with 50 kg water;

S7, Second Year be spring just, and the sandy soil of being planted switchgrass last year water three water every three days continuously, for being beneficial to the sprouting of switchgrass Second Year.

The present invention has following beneficial effect

Switchgrass can survive in desert and can turn green by Second Year, and plant can grow to 2 meters on the ground, and underground root system can grow to 2 meters and well fix the sand, and adopts the mode of sowing to carry out Desert Control, and minimizing human input is planted success then then, had no precedent before.Switchgrass is good herbage simultaneously, is the feed of excellent oxen and horses sheep, and can grows about 10 years continuously.
