Abstract

Soil is the basis for crop growing, good soil environment and good soil quality are premises of high-quality flue-cured tobacco production, Longdong tobacco field soil mainly has the problems that the soil is sticky and heavy, poor in structure, shallow and thin in plough layer and slightly high in PH value, has the barrier levels such as the bottom layer of a plough and influences normal development of tobacco root systems, a part of the tobacco field soil is in lack of the trace elements such as B, Zn and Mn, and therefore flue-cured tobacco growing is not facilitated. A tobacco field soil improvement method mainly comprises the steps that deep-ploughed deep-scarification soil is used, spacing crop rotation planting is conducted, straw is returned to a field, irrigation is improved, fertilizer is applied reasonably, protective cultivation is performed, measures, such as the soil PH value adjustment, suitable for flue-cured tobacco growing are adopted so as to form good flue-cured tobacco growing soil through allocation. Thus, the purposes of improving tobacco leaf quality and benefits are achieved.

Description

Vega soil improvement method

Technical field

The present invention's design is a kind of flue-cured tobacco field soil improvement method.

Background technology

Soil is the basis of plant growth, and good soil environment and soil quality are the prerequisites that high-quality tobacco is produced, the subject matter that Gansu Province east vega soil exists have following some: 1, soil is sticky heavy, and structure is bad.Tobacco-growing soil sand grain content (particle diameter 2-0.05mm) is generally lower than 20%.Soil aeration bad hydraulic permeability, and farming is more difficult.2, plow layer is shallow, has tillage pan and other obstacle level, affects the normal development of flue-cured tobacco root system.During arid, hindered lower soil moisture content and moved upward, during waterlogging caused by excessive rain, affected moisture content and infiltrate soil layer below.3, P in soil H value is higher.Whole county tobacco-growing soil pH value is average 8.3, and meta-alkalescence, is unfavorable for tobacco growth.4, part vega soil lacks the trace elements such as boron, zinc, manganese.

Summary of the invention

The various bad problem existing for solving flue-cured tobacco field soil, I have proposed the soil improvement method of applicable plantation high-quality tobacco through analysis of experiments.

The technical scheme that the present invention takes for technical solution problem: 1, deep ploughing Subsoiling, break the layer that plows, subsoiling is generally greater than 30cm, and every 2-3 is once.2, select suitable planting system, the principal status of public economy of outstanding tobacco in whole rotation system, according to the stable planting scale in cigarette district, overall planning vega total arrangement, guarantees a year, interval or 1 year above rotation system.3, return crop stocks to the field and soverlay technique can improve biological activity of soil, increase soil microbe quantity, promote Soil Respiration, improve soil enzyme activities, can also improve soil physical and chemical property and farmland ecological environment, to improvement soil, balance soil nutrient, especially the deficiency of supplementing soil potassium is played an important role.4, irrigate improving technology.In conjunction with cigarette water conveyance system, exploitation part source of irrigation water, improves irrigation, and accomplishes to adjust with water fertile.Guarantee can irrigate more than 2 times the time of infertility drought-resistant cultivating.5, pay attention to the use of fertilizer and micro-fertilizer, accomplish that fertilizer and inorganic fertilizer are used in conjunction with, join fertile soil fertility, improvement soil.Fertilizer will be selected the livestock essence fertilizer and the pen fertilizer that become thoroughly decomposed cake fertilizer or become thoroughly decomposed, uses bio-bacterial manure and micro-fertilizer.6, selectivity is carried out conservation tillage.Conservation tillage is the novel farming technique of one of turning over respect to tradition.Conservation tillage is carried out no-tillage seeding under the prerequisite that retains increased surface covering, to retain soil natural protection function and to build function.Guarantee that soil structure is not broken and ruptures, promote the soil water, heat, gas fertilizer dynamically long-term in warm, fair, sufficient, suitable state.Adopt conservation tillage can improve soil moisture situation, to carrying out drought-resistant cultivating, there is definite meaning.7, regulate soil acidity or alkalinity, the optimum P in soil H value of tobacco planting is 5.5-6.5, east, Gansu Province tobacco-growing soil pH value is higher, select the fertilizer such as physiological phenomenon nitrogenous fertilizer (as ammonium nitrate phosphorus), potash fertilizer and acid superphosphate, by nest, the technical measures such as executing when transplanting improves the acid-base value in rhizosphere environment.Using humus and soil acidity regulation agent, is also the important channel that regulates P in soil H value.

Beneficial effect of the present invention: the present invention mainly takes the Subsoiling of deep ploughing; interval crop rotation plantation; return crop stocks to the field; irrigate improvement; Rational Application fertilizer, carries out conservation tillage, regulates the applicable tobacco growth measures such as soil acidity or alkalinity; mix good tobacco growth soil, reach the object that improves quality of tobacco and benefit.

Embodiments of the present invention: hold training and field training popularization.

Claims

1. a vega soil improvement method; it is characterized in that mainly taking the Subsoiling of deep ploughing; interval crop rotation plantation; return crop stocks to the field, irrigate improvement, Rational Application fertilizer; carry out conservation tillage; regulate the applicable tobacco growth measures such as soil acidity or alkalinity, mix good tobacco growth soil, reach the object that improves quality of tobacco and benefit.

2. vega soil improvement method according to claim 1, it is characterized in that the Subsoiling of deep ploughing, break the layer that plows, overall planning vega total arrangement, guarantee a year, interval or 1 year above rotation system, return crop stocks to the field and can improve biological activity of soil with soverlay technique, increase soil microbe quantity, promote Soil Respiration, improve soil enzyme activities, exploitation part source of irrigation water, accomplish to adjust with water fertile, guarantee can irrigate more than 2 times the time of infertility, the rationally use of manure use and micro-fertilizer, accomplish that fertilizer and inorganic fertilizer are used in conjunction with, join fertile soil fertility, regulate soil acidity or alkalinity, select physiological phenomenon nitrogenous fertilizer (as ammonium nitrate phosphorus), the fertilizer such as potash fertilizer and acid superphosphate, by nest, the technical measures such as execute when transplanting and improve the acid-base value in rhizosphere environment, improvement soil, for plantation high-quality tobacco provides basic growing environment.
