Description
One, technical field
The invention belongs to town ecological afforestation project technical field.
Two, background technology
By retrieval the national patent net (
Www.sipo.gov.cn/sipo/default.htm) obtain relevant patent of invention of producing no carpet soil formula lawn and have: on October 15th, 1997 ground " method of blanket formula lawn soilless culture " such as Zhang Jiali; Jiangsu Province on the 22nd Jurong aggie Yu Lusheng etc. November in 2000 " soilless lawn blanket and the mode of production thereof "; Not " carpet type does not have the mating system on native environmental lawn " of inventions such as the Wang Xiang of Fudan University on the 10th honor in October calendar year 2001; Opening on August 28th, 2002 must bright " carpet turf " of grey hair; " soilless lawn blanket and the cultivation method thereof " of invention such as Ningde City Inst. of Agricultural Sciences You Yun osmanthus on April 7th, 2004 etc.; " the organic soilless lawn blanket and the quick production methods thereof " of invention such as Zhejiang Academy of Agricultural Science on the 14th Golden Customs honor April in 2004 etc. are all produced according to cultivation technique without soil and principle, and its common technical problem that exists has:
1. lawn planting all is single variety sowing: from organic soilless lawn blanket of no carpet soil formula lawn to the 2004 year flourish invention of Golden Customs in April of Zhang Jiali in 1997 etc., it all is a kind of grass seeds of choosing, be that cold-season turfgrass is (as Yu Lusheng etc., 2000), be warm season turf (as in April, 2004 You Yungui etc.), all not with cold season and warm season grass seeds mixed seeding, and lawn or the careless blanket produced all are single grass seeds plantings, its lawn growth good growing weather or be suitable for the northern cold cold weather, be suitable for southern tropical temperature climate, and be not suitable for the subtropics transitional climate.Therefore, be badly in need of producing a kind of subtropical climate that is suitable in the production, can heat resistanceheat resistant also can be cold-resistant inferior pattern of fever dual-purpose lawn or careless blanket product.
2. non-bent grass level ground, the dark green phase is short: above disclosed patent according to the retrieval and analyze, its innovation point or add at screening and to spin cloth and help lawn intensity and increase, be convenient to transportation (as Yu Lusheng etc., Golden Customs honor etc.), different (as Zhang Bihua in the configuration of host material, invention such as Wang Xiangrong and Zhang Jiali), and grass seeds of selecting for use such as Festuca Arundinacea, single grass seeds such as annual bluegrass and Bermuda grass, in the subtropical zone such as Yangtze River Delta Region plant, its dark green phase all can not keep evergreen in the subtropical zone below 9 months throughout the year.Therefore, be badly in need of producing a kind of subtropical zone that can be suitable for and grow, keep evergreen lawn or careless blanket throughout the year.
3. select matrix cost height for use, mode of production complexity, be difficult for promoting the use of: in the production as the no carpet soil formula lawn of Zhang Jiali production in 1997 needs to add in the matrix fabric of adhesive glue, starch adhesive, add gauze again, though firmly, but the cost height is difficult for large tracts of land production, and its matrix generally also is difficult to obtain; The soilless lawn blanket that Yu Lushengs in 2000 etc. are produced, though matrix be simple and easy to obtain, add special plantation net after, be difficult for making the lawn to be cut into shape easy to use and size etc.; And organic soilless lawn blanket that Golden Customs honor in 2004 etc. are produced, the one, producing must planting in plastic greenhouse, site requirements and cost height, the 2nd, lawn blanket is to be made of the grass seeds organic non-woven fabric different with upper and lower two layers of thickness, produce turf though be convenient to batch production, but the production cost height, the technology that is not easy to is promoted.Therefore, urgent need is developed into the local simple and easy host material that is easy to obtain of utilization, nets the carpet turf volume of no cloth land for growing field crops production in nothing soil nothing, and low-cost and pollution-less, is convenient to the turf production technology and the method for popular popularization.Under above background, our seminar tackled key problems through effort in 4 years from calendar year 2001, had overcome above-mentioned technological deficiency, had succeeded in developing the evergreen mixed seeding turf volume of the four seasons that is suitable for subtropics transitional climate planting.
