Abstract
The present invention relates to a ploughing-free cultivation method by using the roots or the stubbles of Chinese trumpet creeper, which is a cultivation method for planting crops. The method of the present invention adopts a cultivation mode of interplanting Chinese trumpet creeper among other crops without ploughing. Chinese trumpet creeper is interplanted among other crops in summer and is left to grow continuously after the crops are mature and are harvested. The green herbs of Chinese trumpet creeper on the ground surface are cut off at fixed intervals before other crops are sown, and the roots and the stubbles of the Chinese trumpet creeper are cut up and harrowed, so that belt interplanting without ploughing can be realized. Chinese trumpet creeper is interplanted again among other crops in the next summer. The method of the present invention can save a large quantity of manpower and power machines, avoid the phenomenon of hard soil and increase the yield of the crops.
Description
Utilizing sweet potato root stubble zero tillage is a kind of methods of cultivation of proportion of crop planting.
Traditional crops methods of cultivation will be ploughed soil, preparing seedbed before new crop sowing, and along with the development of agricultural mechanization, some area has replaced handwork with machinery; This methods of cultivation need a large amount of labour and dynamic power machine, in addition the suitableeest sowing time of most of crops very short, bring very large difficulty to farming, and subject to corrode through the soil ploughed, by evaporation and the more moisture of runoff loss and nutriment, thereby reduce the above agriculture potentiality of earth.Adopt in the world a kind of no-tillage farming system since nineteen fifty-seven: after preceding crop harvesting, do not plow, new crop seed is directly sown in the soil of covering of previous crops stubble always.Although this farming system can save a large amount of labours, dynamic power machine, and because covering, previous crops stubble reduces rainwash, reduce the absorption of evaporating and increase rainfall, but because it is not plough and just plant other measures of not taking on original topsoil, thus to original topsoil without any processing and nutrition, and cause soil compaction hard, arability reduces, and farmland running to weeds and damage by disease and insect plough plant even more serious.
The object of this invention is to provide a kind of methods of cultivation, it had not only had no-tillage advantage but also can overcome the shortcoming that has soil compaction sclerosis arability that no-tillage method causes to reduce.
Growing state, the root function of applicant to sweet potato crop done test for many years, observation, and can do comprehensive analysis in conjunction with the growth substrate of crops, the methods of cultivation that propose a kind of science on the basis of test for many years, farming practice " are utilized sweet potato root stubble zero tillage ", thereby solve the unsolved series of problems of the existing methods of cultivation.
The basis of sweet potato and other crop zero tillage and interplantings is: sweet potato belongs to a more year raw legume, and cauline leaf is the volt shape of crawling, and main root can go deep into that upper strata 2.3-2.7 rice side fibrous root is many and not only fluffy but also intert in length and breadth compared with other green manure root systems, cutting force is strong.According to test for many years, the machine cuts power activity of sweet potato fibrous root, can make the soil of whole topsoil become loose, increase granular structure and the soil porosity of soil, soil is not hardened, no matter clay, ballast soil, Qiang Tudou there will not be hardening phenomenon, the complete superior structural that is applicable to crop growth that forms evenly of soil plough horizon.
In practice, plant sweet potato and carry out loose, the in small, broken bits and soil resistance that no-tillage soil ploughs than tractor and alleviate, illustrate that the interaction energy of sweet potato root stubble changes soil structure, be well suited for carrying out zero tillage with the crops interplanting such as cotton, wheat, corn, cereal.Sweet potato lateral root be give birth to a large amount of root nodule groups, 14.4～26.6, the effective root nodule of every strain sweet potato in the above soil layer of 0-20cm according to investigations, in the dark soil layer of 20cm, in every square metre, effectively nodule weight is 46.8 grams, close 468 kilograms of effective root nodules of per hectare, these powerful rhizobium can be fixed aerial a large amount of nitrogen, analyze according to sweet potato plant composition, initial bloom stage green grass nitrogen content is 0.50%, phosphorous plain 0.13%, chloride containing potassium 0.43%, fresh nitrogen content 0.62%; Produce 22500 kilograms of green grass with per hectare, fresh 7500 kilograms of meters, acrial part can obtain 112.5 kilograms of purity nitrogens, and under ground portion can obtain 46.5 kilograms of purity nitrogens, also has the elements such as phosphorus, potassium, all by sweet potato root system agency part input soil, changes the chemical constitution of soil.Sweet potato and the interplanting of other crops are no-tillage, root nodule group and root system are retained and are kept in soil the state that can be absorbed by other crops, soil fixing of soil and conservation of water keeping fertility after no-tillage strengthens, ecological condition makes moderate progress, the corresponding raising of the liquid manure that crop depends on for existence and nutritional condition, so carry out no-tillage in and fertilise not, make crop obtain high yield.
The particular content of the inventive method is: zero tillage is carried out in sweet potato and crops interplanting.Lunar calendar second of the three ten-day periods of the hot season by the drilling of sweet potato seed remove cotton or the row of summer sown crop in, treat the ripe results of cotton or summer sown crop, leave sweet potato continued growth; Before other crops of sowing, sweet potato above ground portion is prescinded to a band at a certain distance, sweet potato root stubble chopping is raked with hoe or disk harrow, can no-tillage no the fertilising cover that becomes band broadcast, results when sweet potato seed is ripe in summer, the sweet potato root stubble chopping zero tillage summer sown crop of raking of making the best use of time is interplanted again sweet potato farming like this mid-term and is formed the growth cycle that sweet potato and other crops are interplanted when it grows in its row.
The inventive method can take sweet potato and cotton interplanting to carry out zero tillage, and lunar calendar second of the three ten-day periods of the hot season is by sweet potato drilling or be sown in cotton row, after the ripe results of cotton in winter, leaves sweet potato continued growth; Spring sweet potato ground green grass part is prescinded to a band at a certain distance and the chopping of sweet potato root stubble is raked after the no-tillage cover that becomes band broadcast cotton.
The inventive method also can take sweet potato, wheat or corn or soybean, paddy interplanting to carry out zero tillage, lunar calendar second of the three ten-day periods of the hot season by sweet potato drilling be sown in corn or soybean, paddy capable in, the ripe results of autumn corn or soybean, paddy, sweet potato ground green grass part is prescinded to a band at a certain distance, and the no-tillage cover that becomes band is broadcast wheat after the chopping of sweet potato root stubble is raked, can zero tillage corn or soybean, paddy etc. after wheat and the ripe results of sweet potato.
Employing utilizes sweet potato root stubble zero tillage can make full use of the effect chesson of sweet potato root system, increases soil fertility, and improves physics, the chemical constitution of soil, makes its suitable crop growth, obtains the good effect of higher yield of crops.Test for many years shows, plant the no-tillage improvement to soil structure of sweet potato larger, plant before 1 year its bulk density of soil of sweet potato is planted and alleviate 10.52%, porosity increases by 10.29%, water-stable granular structure increases by 48.22%, the soil organic matter increases by 0.06%6, nitrogen content increases by 0.0044%, plant 2 years its bulk density of soil of sweet potato and alleviate 14.28% before planting, porosity increases by 16.64%, water stability closes kernel structure increases by 90.33%, the soil organic matter increases by 0.18%, nitrogen content increases by 0.0099%, within the 3rd year, the soil organic matter increases by 0.28%, nitrogen content increases by 0.024%.The effect that the methods of cultivation of the present invention improve crop yield in production practices is also clearly: nineteen sixty-eight is selected 2/15 hectare of lime soil, both there is no irrigation conditions and fertilizer application condition, the hills of serious wind erosion drought unfertile land do experiment field compares again, sweet potato in front season kind, after gathering in the crops seed, plough to half and cover the blue or green cotton of planting, produce 37.5 kilograms of gined cottons, early, generally there is red autumnal leaves branch maize ear rot in the low early ageing of strain, blow-of-cottons; Second half ground adopts the inventive method farming, and the large peach of peach is many, grows vigorous, produces 75 kilograms of gined cottons and occurs without red autumnal leaves branch maize ear rot.
" utilizing sweet potato root stubble zero tillage " proposed by the invention, can save that ploughing levels land needs a large amount of labours, the dynamic power machine of use; Reduce agricultural cost, and solve the soil compaction sclerosis problem that external no-tillage system farming brings, simultaneously because sweet potato cauline leaf is in the bridging effect on ground, control the growth of crop growth phase weeds, both can improve output, the general expenses of having save again weed killer herbicide etc., has actively significant economic benefit.
