Description

The paddy soil improvement method of a kind of cigarette-rice rotation system
Technical field
The present invention relates to technical field of land improvement, the paddy soil improvement method of especially a kind of cigarette-rice rotation system.
Background technology
A large amount of tobacco rods is produced after China's cigarette-rice crop rotation district flue-cured tobacco of per season results.Nonirrigated farmland tobacco rod also field can produce serious disease, but cigarette-rice crop rotation is through the submerging treatment of rice season, and disease is relatively less.Therefore growth-promoting cigarette-rice rotation system, cigarette-rice rotation system refers on same block rice field, first plants cigarette in same year, plant immediately after receiving cigarette wholely one season late rice cropping system.At present, cigarette-rice crop rotation is the important rice field-upland field rotation system in south China area, and in Anhui, Fujian, Hunan, Jiangxi, Guangdong, the province such as Guangxi add up to cultivated area to reach 300,000 hm 2, tobacco rod also Tian Yan-rice crop rotation district becomes universal phenomenon gradually.
There are some researches show that straw-returning can improve soil structure, reduce the bulk density of soil, increase soil porosity; And a large amount of nutrients that stalk contains can improve soil nutrient, realize Reducing amount of chemical fertilizer applied, effectively reduce costs.In addition, because tobacco rod Nitrogen-and Phosphorus-containing potassium enriches, and hypothesis rationally can go back field, and its N P and K be rich in can timely and effectively discharge, and both will can supplement soil nutrient, can be again the nutrition that paddy rice provides a large amount of.Therefore Appropriate application tobacco rod is to improving soil structure, maintains soil nutrient balance, reduces chemical fertilizer and drops into, and the friendly agricultural of development environment is significant.
But, also there are some problems in cigarette-rice rotation system still to fail to solve, as: tobacco rod content of lignin is high, and decomposition is usually relatively slower, although more existing technical schemes can promote the decomposition of agricultural crop straw preferably and have certain improvement and castering action to soil fertility at present.But also well do not promote mode or the method for decomposition in field for tobacco rod, this severely limits tobacco rod also field effect that paddy soil improvement and fertility are promoted.Therefore, we are badly in need of inquiring into one can significantly improve tobacco rod original position also field decomposition speed in cigarette-rice rotation system, and effectively improves the method for paddy soil.
Summary of the invention
The technical problem to be solved in the present invention is: the paddy soil improvement method providing a kind of cigarette-rice rotation system, and improve decomposition speed and the nutrient release rate of tobacco rod, thus soil nutrient is significantly improved, paddy soil is improved.The present invention effectively can solve current cigarette-rice crop rotation realistic problem that also tobacco rod decomposition in field is slow, soil fertility is low, for rice high yield efficiently provides technical guarantee.
The paddy soil improvement method of a kind of cigarette-rice rotation system, cigarette described in it-rice rotation system refers on same block rice field, first grows tobacco in same year, gather to plant immediately after tobacco leaf wholely one season late rice cropping system, it is mainly characterized in that, the paddy soil improvement method of described cigarette-rice rotation system is applied to after tobacco leaf all gathers, before cultivating a second crop of rice, specifically comprise the steps:
Step 1: segment tabacco straw being cut into 5-10cm in original place, field, then will promote that the Chemical Mixed Fertilizer of tobacco rod decomposition evenly spreads fertilizer over the fields into field, behind the whole ground of rotovator, Chemical Mixed Fertilizer and paddy soil, the tabacco straw segment of described promotion tobacco rod decomposition fully mix.
In described step 1, the Chemical Mixed Fertilizer of described promotion tobacco rod decomposition comprises: dolomite dust and quicklime.
Step 2: evenly spread fertilizer over the fields the Chemical Mixed Fertilizer of improvement paddy soil into field, behind level land, Chemical Mixed Fertilizer and the paddy soil of described improvement paddy soil fully mix.
In described step 2, the Chemical Mixed Fertilizer of described improvement paddy soil comprises: dolomite dust, urea, potassium nitrate and bacillus subtilis.
Further, promote described in step 1 that the consumption of the Chemical Mixed Fertilizer of tobacco rod decomposition is 30 kgs/acre; And in the oeverall quality of dolomite dust and quicklime in the Chemical Mixed Fertilizer of described promotion tobacco rod decomposition for 100%, then both recipe ratios are respectively: dolomite dust (33-67%) and quicklime (33-67%).
Further, the consumption improveing the Chemical Mixed Fertilizer of paddy soil described in step 2 is 30 kgs/acre; And in the oeverall quality of dolomite dust in the Chemical Mixed Fertilizer of described improvement paddy soil, urea, potassium nitrate and bacillus subtilis for 100%, then the recipe ratio of four is respectively: dolomite dust (50-70%), urea (13-25%), potassium nitrate (13-25%), bacillus subtilis (0.3-1%).
Promote that the composition of the Chemical Mixed Fertilizer of tobacco rod decomposition comprises quicklime and dolomite dust, can promote that the decomposition of tobacco rod is: the pH of quicklime and dolomite dust is higher, tobacco rod also field time can improve soil pH value, thus promote the decay of microorganism, accelerate the decomposition of tobacco rod.
Beneficial effect of the present invention: in prior art, comparatively consolidation, gas permeability are poor for the soil in cigarette-rice crop rotation district, after the inventive method process, nutrient is provided on the one hand for soil and paddy growth, enhance soil porosity and the gas permeability in cigarette-rice crop rotation district on the other hand, thus improve soil structure.Particular content is as follows:
(1) paddy soil pH is lower, under acid ground condition (water paddy soil is substantially all acid), use the pH that Chemical Mixed Fertilizer that quicklime and dolomite dust make can improve soil, make soil nutrient be easier to rice absorbing and utilize, thus play the effect of improvement soil.Dolomite dust can not only regulate the pH of soil, and is rich in calcium and magnesium because of it, can improve the calcium-magnesium content of paddy soil.
(2) also the initial stage of field tobacco rod decomposition needs loss soil nitrogen, urea in mixing fertilizer and potassium nitrate can provide sufficient nitrogen for tobacco rod decomposition, promote tobacco rod decomposition, and dolomite dust can increase porosity and the gas permeability of soil, improve soil water-reataining fertilizer-keeping ability, thus reach the object of improvement soil.In addition, bacillus subtilis effectively can remove the germ that also field tobacco rod is brought into, has obvious effect to the clean health of soil.
(3) soil improvement method of the present invention is simple, the processing time is short, effect stability, cost are low.
In sum, the present invention be adopt first quicklime+dolomite dust+urea+potassium nitrate+bacillus subtilis with the use of method, the method can promote tobacco rod at the decomposition of land for growing field crops original position and improve paddy soil, but also the decomposition speed of field tobacco rod and nutrient release rate significantly strengthen, soil nutrient significantly improves, and rice yield also significantly improves simultaneously.
