Abstract
The invention relates to a seed production cornfield continuous cropping obstacle conditioner. The conditioner is prepared by mixing modified furfural residue, cow dung, 5406 bacterial manure, water retaining agent and polyvinyl alcohol at a weight ratio of (37.95-42.94):(56.93-61.96):(0.04-0.06):(0.04-0.06):(0.01-0.03) and then performing harmless treatment. The conditioner provided by the invention not only promotes the resource recycling, but also solves the problems that the planting area of seed production corn is large, the continuous cropping time is long, the nutrient proportion of the seed production cornfield is unbalanced, many soil-borne diseases are caused, the soil is hardened, the organic content is reduced, the water storage function is weakened and the like, thereby achieving the aims of providing crop nutrition, improving the organic content of the soil, enhancing the water storage function of the soil and improving the soil structure.
Description
Technical field
The present invention relates to agricultural and use the soil field, relate in particular to a kind of seed production corn field continuous cropping obstacle amendment.
Background technology
Irrigated area, Hexi Corridor inland has advantageous natural condition and advantage in geography, attracted Dupont pioneer, U.S. Meng Shan all, step on the families more than 90 such as extra large pioneer species industry, China seed industry, East Asia, Liaoning, Beijing moral agriculture, Ao Ruijin, Dunhuang and plant industry group both at home and abroad, set up 1,500,000 mu, corn seed producing base, account for 1,500,000 mu, the corn seed producing industry has developed into one of mainstay industry of the irrigated area increasing peasant income of inland, the west of a river, growth of agricultural efficiency.The subject matter existed at present is: the seed production corn cultivated area is large, and the continuous cropping time limit reaches 15 years, and due to continuous cropping year limit for length, seed production corn field nutrients ratio is unbalance, and the physiological disturbance of nutritional deficiency often occurs; Due to continuous cropping year limit for length, soil-borne disease is more, fertilizer input amount deficiency in addition, and the chemical fertilizer excess is used, soil compaction, organic content descend, and the water storage function weakens, and the fertilising cost increases; The Chemical Mixed Fertilizer effective constituent circulated on market and ratio do not meet seed production corn field Nutrients Present Situation and the corn assimilation ratio to nutrient, and do not possess water conservation, the effect of improving the soil; Cause the seed production corn quality and yield to descend, Some Species industry group flows to Xinjiang, Inner Mongol and Ningxia, has affected the Sustainable development of local area seed production corn industry.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind ofly possess water conservation, the seed production corn field continuous cropping obstacle amendment of the effect of improving the soil.
For addressing the above problem, a kind of seed production corn of the present invention field continuous cropping obstacle amendment, it is characterized in that: after this amendment is mixed by 37.95 ~ 42.94:56.93 ~ 61.96:0.04 ~ 0.06:0.04 ~ 0.06:0.01 ~ 0.03 weight ratio by modified furfural residue, cow dung, 5406 bacterial manure, water-holding agent, polyvinyl alcohol, through the harmless treatment gained.
Described modified furfural residue refers to by every 1000kg furfural dregs and adds 21.33 ~ 25.60kg (NH
4)
2CO
3, making the pH value of furfural dregs is 5.0 ~ 6.0, obtaining particle diameter after sieving is 2 ~ 5 mm, and containing organic 66 ~ 70%, C 49 ~ 64%, full N 0.50 ~ 0.61%, full P 0.30 ~ 0.36%, the modified furfural residue of full K 1.10 ~ 1.18%.
The particle diameter of described cow dung is 2 ~ 5 mm, containing organic matter 14.50%, and full N 0.52 %, full P0.28 %, full K 0.16%.
The particle diameter of described 5406 microbial inoculums is 0.01 ~ 0.05 mm, its living bacteria count >=2.0 hundred million/g.
The particle diameter of described water-holding agent is 1 ~ 2mm, water absorbent rate 645g/g.
The particle diameter of described polyvinyl alcohol is 0.05 ~ 2 mm, and molecular mass is 5500 ~ 7500, and value is 6.0 ~ 8.0, and viscosity is 12 ~ 6.
The production method of a kind of seed production corn as above field continuous cropping obstacle amendment comprises the following steps:
(1) by the proportioning weighing;
(2), after modified furfural residue, cow dung, 5406 bacterial manure being mixed, obtain mixture;
(3) add CO (NH in described mixture per ton
2)
24.0 ~ 5.0kg, making its C/N is 25:1; Then adding water makes its water content reach 50 ~ 55%, mix, all insert dark 2.5 meters that dig in advance, wide 2 meters, in the hole of long 4 ~ 10 meters, tight with the mud grave, bank up after fermentation 140 ~ 150d at the air-dry 28 ~ 30d in shady and cool dry place, make its water content be less than 10%, finally cross the 50mm sieve, then add respectively water-holding agent and polyvinyl alcohol mix evenly and get final product.
The present invention compared with prior art has the following advantages:
1, the furfural dregs of selecting due to the present invention, aboundresources, furfural dregs is containing organic 66 ~ 70%, C 49 ~ 64%, full N 0.50 ~ 0.61%, full P 0.30 ~ 0.36%, full K 1.10 ~ 1.18%, heavy metal ion Hg, Cd, Cr, Pb content all are less than the agricultural organic waste of GB8172-87 regulation and control content standard; Due to the cow dung that the present invention selects, aboundresources, containing organic matter 14.50%, full N 0.52 %, full P0.28 %, full K 0.16%.Therefore, the present invention utilizes furfural dregs, cow dung is synthesized the continuous cropping obstacle amendment, by furfural dregs, cow dung long-acting, the synergy of bio-bacterial manure, the water conservation of water-holding agent, the effect of improving the soil of polyvinyl alcohol combines together, not only promoted the recycle of resource, and it is large to have solved the seed production corn cultivated area, continuous cropping year limit for length, seed production corn field nutrients ratio is unbalance, soil-borne disease is more, soil compaction, organic content descends, the problems such as water storage function weakening, reach the supply crop alimentary, promote soil organic matter content, improve soil water storage function, improve the purpose of Soil structure.
