Abstract
The present invention relates to a kind of farmland soil modifying method, the method that Shajiang black soil is specially improved using crop material charcoal, the problems such as solving the viscous weight of Shajiang black soil, farming difference.In low yield Shajiang black soil agricultural land soil, crop material charcoal is applied into field ditch, earthing is buried.It is of the invention first to apply field ditch in farmland trench digging, then by charcoal, improve soil physical property, lift retention capacity of soil, absorbability of the increase crop to liquid manure in soil.The present invention is to increase charcoal on the basis of conventional farmland soil cultivation mode, fundamentally realize the purpose of Shajiang black soil improvement, it is wide with raw material sources, it is with low cost, application process is simple, crop straw burning pollution air can also be reduced, increase the effect of soil carbon capacity, with huge application value.
Description
Technical field
The present invention relates to the modification method of soil, and in particular to a kind of method that utilization crop material charcoal improves Shajiang black soil.
Background technology
As Development of China's Urbanization is promoted, cultivated area is constantly reduced, in addition chemical fertilizer is largely applied, soil texture is destroyed in various degree, and soil quality is decreased obviously, China's foodgrain self-sufficiency and grain security are had a strong impact on, failed to keep an appointment 270.37 ten thousand t [Hong Shuman, Hao Jinmin, Zhouning County as 2000-2008 Huang-Huai-Hais directly contribute grain yield net loss because farmland quality is reduced, the influence EIs changed Deng Huang-Huai-Hai plains arable land use change and to grain-production general layout, 2014 (21):268-277].Therefore, centering low-yield soil improvement has certain realistic meaning.Shajiang black soil is as the important low productive soil of Huang-Huai-Hai plain, and about 60,000,000 mu of area accounts for the 21.39% of area's total area under cultivation, accounts for the 4.58% of national grain acreage, is still one of larger mid and low yield soilses of China's area at present.As can be seen here, lifting low yield farmland soil how is effectively improved, the sustainable use of soil resource is maintained, it has also become outstanding problem urgently to be resolved hurrily.
Shajiang black soil is parent material development, predominantly calcareous matrix by fluvio-lacustrine sediments thing and Recent River Sediments thing etc., and clay content enriches, and clay mineral is mainly with 2:Based on 1 type smectites dilatancy secondary mineral, and montmorillonite is met water and can expanded, and causes the blocking of capillary pore, soil active porosity is few, and then prevents to ooze under moisture, and effective soil water store capacity is few, small to the regulation storage capacity of moisture, excessive rainfall easily causes this area's impeded drainage.The viscous weight of the soil texture is embodied in, drying shrinkage bulking, easily drought easily flood, soil tilth are poor, are unfavorable for crop growth, seriously constrain the raising of grain yield.In recent years, straw-returning technology is in China's each department extensive use, returning to the field mode is mainly by direct returning to farmland, a large amount of wheats, maize straw shows many benefits, such as improve the soil organism, reduce soil weight etc., but because Straw decomposing speed is slow, wheat, Corn Rotation System time interval is short, annual crop-residue incorporation is huge, in addition Shajiang black soil glues weight characteristic, returning to the field stalk is difficult to enter soil, hinder straw degradative, returning to the field stalk is caused to be difficult to effective utilization, a large amount of improving straw mulching upper soll layers influence crop growth on the contrary, aggravate agricultural land, therefore the obstacle of Shajiang black soil poor quality can not fundamentally be overcome.
In recent years, the Utilizing question of stalk resource is paid close attention to by people, and China produces the t of agricultural crop straw about 700,000,000 every year according to statistics, because current straw utilization economic benefit is low, and peasant often in order to cost-effective, by the direct on-site incineration of stalk, causes atmosphere pollution serious.Therefore, be badly in need of seeking one kind can effectively utilizing crop material in environmentally friendly manner, again can fundamentally improved soil technology, realize crop material " turning waste into wealth ", the target of soil resource sustainable use doulbe-sides' victory.
The content of the invention
The technical problem of solution：The purpose of the present invention is to overcome the deficiencies in the prior art and provide a kind of method that utilization crop material charcoal improves Shajiang black soil, and this method not only overcomes the problem that crop material is difficult by, moreover it is possible to fundamentally overcome the obstacle of Shajiang black soil poor quality.
Technical scheme：A kind of method that utilization crop material charcoal improves Shajiang black soil, comprises the following steps：
Step 1, ditched using tractor mouldboard plow, ditching depth 25-30cm, width 20-25cm, adjacent ditch spacing 20-25cm；
Step 2, wheat, maize straw are collected, stalk is smouldered under the conditions of 500 DEG C, is cooled to after normal temperature, then ground 2mm sieves of crossing obtain straw biological charcoal；
Step 3, charcoal sowing amount is 5t/ha, is uniformly sprinkled into field ditch, and carries out earthing burial immediately；
Step 4, after charcoal is buried, with conventional fertilizer application amount, using mechanical rotary tillage mode plowed soils, rotary tillage depth 10-15cm.
Beneficial effect：
The present invention is to increase charcoal on the basis of conventional farmland soil cultivation mode, this method has simple to operate, it is practical, environmentally friendly the advantages of, after charcoal is manured into soil, with its light weight, porosity characteristic can improve soil porosity, be conducive to improving drainage of soil ability, reduce the soil weight, macro aggregate is promoted to be formed simultaneously, promote the adsorption capacity of soil nutrient ion, fundamentally Shajiang black soil is structural and production performance for improvement, overcome the obstacle that soil quality is low, crop material can effectively be utilized in environmentally friendly manner by realizing, again can the effective structure of improved soil purpose.
Embodiment：
Following examples further illustrate present disclosure, but should not be construed as limiting the invention.Without departing from the spirit and substance of the case in the present invention, the modification and replacement made to the inventive method, step or condition, belong to the scope of the present invention.Unless otherwise specified, the conventional meanses that technological means used in embodiment is well known to those skilled in the art.
Embodiment：A kind of method that utilization crop material charcoal improves Shajiang black soil, comprises the following steps：
Step 1, before autumn sowing, ditched using tractor mouldboard plow；
Step 2, in the field ditch that charcoal is uniformly applied to step 1, earthing is buried；
Step 3, using conventional fertilizer application amount, with mechanical rotary tillage mode plowed soils, increase sowing suitability.
The utilization tractor mouldboard plow trench digging, ditching depth 25-30cm, width 20-25cm, adjacent ditch spacing 20-25cm.
Stagger successively the utilization tractor mouldboard plow trench digging, annual trench digging position.
The charcoal is smouldered by wheat, maize straw under the conditions of 500 DEG C, is cooled to after normal temperature, then ground 2mm sieves of crossing are obtained.
The charcoal sowing amount is 5t/ha, is uniformly sprinkled into field ditch, and carries out earthing burial immediately；After the charcoal is buried, with conventional fertilizer application amount, using mechanical rotary tillage mode plowed soils, rotary tillage depth is 10-15cm.
