Author summarizes with regard to the research of Nicotiana tabacum L. allelopathic Auto toxicity Yu continuous cropping obstacle, and the research for deepening this aspect further provides reference.
Allelopathy refers to the chemical ecology phenomenon that a kind of live plant produces and grows to the contiguous accompanying plant growth of Environment release secondary metabolites and then impact with volatilization, leaching, secretion and grading mode. Allelopathic Effect in Plants should have three basic features: 1. interaction Subjective and Objective is all plant; 2. the chemical substance interacted is secondary substance, and must flow through suitable approach and enter people's environment, not included in the secondary substance of plant variation in vivo operating; 3. allelochemical is mainly used in affecting the growth promoter of self or contiguous plant, if for chemical communication or contaminated environment between plant, as reported to the police, or some trees release volatile matter and nitrogen oxide form smog etc. and be not admitted to STUDY ON ALLELOPATHIC EFFECTS scope. Produce inhibiting phenomenon when receptor and donor belong to a kind of plant, be called allelopathic Auto toxicity. Auto toxicity is a kind of generation growth inhibited effect in kind, is one of interactional mode in plant species, is a part for intraspecific relationship, is a kind of specific form of struggle for existence.Analyzing from Darwinian evolution sight, Auto toxicity is in that to alleviate the competitive pressure of inside of the same race. Auto toxicity mode has the marked feature of following three aspects: selectivity, concentration effect, combined effect effect.

Selection of land is wholely: being typically chosen hillside and plant pacifically, preceding crop is 3 pieces of the soil of Semen Tritici aestivi. After optional one piece of planting site as interplanting, carry out wholely. First soil being ploughed deeply 20 cm, plays railway carriage or compartment, railway carriage or compartment width 1.8m, the railway carriage or compartment of above-mentioned interplanting, a railway carriage or compartment is used for planting the Rhizoma Pinelliae one railway carriage or compartment for planting flue-cured tobacco, by that analogy. Then, for planting the base manure of Rhizoma Pinelliae row: fertilizer 100 kgs/acre (organic > 75%, nitrogen [N3-]2kg、P2O51.5、K2O1.5 kg/acre), calcium superphosphate or 60 kgs/acre of calcium and magnesium phosphorus or phosphorus ammonium 15 kgs/acre (amount to P2O57-8 kg/acre). For planting the base manure of flue-cured tobacco row: (organic > 75%, wherein contains nitrogen [N to fertilizer 100 kgs/acre3-]2kg、P2O51.5kg、K2O1.5kg/ mu), nitrogen-phosphorus-potassium compound fertilizer 50 kgs/acre (wherein contains nitrogen [N3-]5kg、P2O55、K2O12.5 kg/acre). Again soil is ploughed deeply 20 centimetres by point railway carriage or compartment, fertilizer is uniform with mixing with soil, as experiment plot.
Arbitrarily select one piece and apply farm manure, for planting the row base manure of the Rhizoma Pinelliae: fertilizer 100 kgs/acre (organic > 75%, nitrogen N2kg, P2O51.5、K2O1.5 kg/acre), calcium superphosphate or 60 kgs/acre of calcium and magnesium phosphorus or phosphorus ammonium 15 kgs/acre (amount to P2O57-8 kg/acre), neat seedling stage (by the end of April), tuberization phase (by the end of May), growth most productive period (by the end of June) and later stage (by the end of August) impose carbamide 3 kgs/acre+phosphorus ammonium 2-3 kg/acre (be watered bold and vigorous execute best) respectively., then soil is ploughed deeply 20 centimetres, by uniform to fertilizer and mixing with soil; Individually plant the Rhizoma Pinelliae, compare plot as the Rhizoma Pinelliae; (organic > 75%, wherein contains nitrogen [N to optional one piece of organic fertilizer 100 kgs/acre3+]2kg、P2O51.5kg、K2O1.5kg/ mu), nitrogen-phosphorus-potassium compound fertilizer 50 kgs/acre (wherein contains nitrogen [N3+]5kg、P2O55、K2O12.5 kg/acre), the nitrogen-potassium compound fertilizer that respectively topdresses when transplanting 1 week 3 weeks (total of topdressing for twice N5, K2O10 kg/acre), then soil is ploughed deeply 20 centimetres, fertilizer is uniform with mixing with soil, individually plant flue-cured tobacco, as tobacco control plot.
2, the planting patterns of the Rhizoma Pinelliae is:
Sowing: at the beginning of 5 months, sow after wheat harvest. During sowing, line-spacing is maintained at 20 cm, and this is mainly by under seeder, and the spacing of ditching plow determines, by plough from being adjusted to 20 centimetres, and line-spacing namely 20 centimetres. Seeder can be earthed up voluntarily, after sowing, it is not necessary to artificial ridging. General mu sowing quantity about 20 kilograms. After Rhizoma Pinelliae sowing, do not water, in case it is rotten to plant stem rot. Sowing about one month, the seedling of Rhizoma Pinelliae will be broken through the soil, and when height of seedling reaches 5 cm, will carry out the seedling management of some necessity.
Seedling management: the seedling management of Rhizoma Pinelliae mainly has weeding to loosen the soil, applies fertilizer, waters and the prevention and control of plant diseases, pest control. Head loosens the soil firstly talk about weeding.
Weeding is loosened the soil: the Rhizoma Pinelliae in seedling stage often to carry out weeding, because grass can hinder the growth of Rhizoma Pinelliae Seedling. In this period, it is generally adopted artificial weeding, and there is no regular time and number of times restriction, it is seen that have grass in ground, remove just passable with hoe, owing to Rhizoma Pinelliae Seedling at this moment is also very small and weak, forbid to use herbicide. Further, while weeding, it has been also carried out loosening the soil. But must noting the degree of depth, general pine soil depth is just passable at 3 cm, not so, can hurt root. Below, the fertilizer management in Rhizoma Pinelliae seedling stage is had a talk about.
Early stage is applied fertilizer: the Rhizoma Pinelliae of neat seedling stage (by the end of April) and tuberization phase (by the end of May) mainly uses compound fertilizer, and every mu of consumption executes carbamide 3 kgs/acre+phosphorus ammonium 2-3 kg/acre. Fertilising carries out after being generally selected in rain, and mode is that hands spreads, and compound fertilizer is sprinkling upon Miao Dili, and compound fertilizer will dissolve voluntarily. If applying fertilizer at fine day, must spray water after fertilising, promoting compound fertilizer to dissolve, not so can burn seedlings.
Watering: the Rhizoma Pinelliae in seedling stage, the main mode adopting sprinkling irrigation keeps the skin wet. Generally, once water spray within every 6 days, is carried out just passable.
The prevention and control of plant diseases, pest control: the insect pest in Rhizoma Pinelliae seedling stage is less, is mainly disease. Harm the most seriously virosis, shows themselves in that blade turns yellow gradually, last whole leaf withered death. Therapeutic Method is: the lime milk solution with 5% carries out foliage-spray, even spray 2-3 time, and interval is 5-7 days, it is possible to play therapeutical effect.
Field management: when height of seedling reaches 10 cm, has advanced to the field management stage, below, we have a talk about the field management of Rhizoma Pinelliae. The field management of Rhizoma Pinelliae mainly has: water and draining, middle weeding, fertilising and the prevention and control of plant diseases, pest control. First firstly talk about watering waters and draining.
Water and draining: Rhizoma Pinelliae happiness is wet is afraid of drought, and hydropenia easily causes aerial parts and withers, so it is noted that science is watered, Rhizoma Pinelliae at this moment is mainly irrigated with water channel, generally within every 15 days, waters a water. It should be noted that once water can not be too many when watering, it is advisable with moistening epidermis soil.Further, it is noted that draining during excessive rainfall, otherwise, bad root phenomenon can be caused.
Middle weeding: the Rhizoma Pinelliae in field management stage also wants frequent weeding, still adopts artificial weeding mode, and number of times and time are not also fixed. And the root system integrated distribution of Rhizoma Pinelliae is in the topsoil of 12-15 centimetre, so the intertillage degree of depth is no more than 5 centimetres, in order to avoid hindering root, hinder the growth of Rhizoma Pinelliae.
Mid-term topdresses: the Rhizoma Pinelliae in field management stage generally uses carbamide, and every mu of consumption is 20 kilograms. Fertilization mode has two kinds: sprays and executes with punching. Spraying is be blended in aerosol apparatus by water and fertilizer, is sprayed on the blade of Rhizoma Pinelliae. Rushing Shi Shiyu to water to combine and carry out, the bucket being mixed with fertilizer is placed on water channel mouth place, opens the water valve below bucket, fertilizer will flow in Rhizoma Pinelliae ground along with current, reaches to supplement the effect of fertilizer. The general field management stage applies fertilizer 3-4 time, and interval is about 20 days, can ensure that Rhizoma Pinelliae grows.
The prevention and control of plant diseases, pest control: the Rhizoma Pinelliae in field management stage, mainly has leaf spot and virosis. Showing as the speckle having brown on blade at the beginning of leaf spot, speckle becomes big subsequently. Finally, blade withered death. The method preventing and treating leaf spot is: spraying with 500 times of liquid of ferrous sulfate, every 7-10 days 1 time, continuous 2-3 time, effect is better. The symptom of virosis, we introduced, and did not just speak more here. Prevention and controls is: spray with 5% lime milk solution, continuous 2 times, and interval is 5 days, it is possible to treatment virosis.
The insect pest of Rhizoma Pinelliae is mainly Holotrichia diomphalia Bates larva and hornworm. Holotrichia diomphalia Bates larva is a kind of to endanger serious subterranean pest-insect, stings the tuber of food Rhizoma Pinelliae, and prevention and controls is: with the phoxim solution spray of 50%, every 5-7 days 1 time, continuous 2-3 time. Hornworm is multiple is born in 7-8 month, stings the blade of food Rhizoma Pinelliae, carries out foliage-spray with the phoxim solution of 50%, and continuous 2 times, interval is 5 days, it is possible to kill hornworm. Rhizoma Pinelliae is typically in gathering in the crops October. Below, we introduce the collecting method of Rhizoma Pinelliae.
Gather: results Rhizoma Pinelliae to use professional tool, and you see, instrument when this three teeth creeper on picture is exactly gather in the crops, and are dug by the tuber being embedded in underground with creeper, pick up in engagement just passable. But when plane it should be noted that do not exert oneself very much, in order to avoid tuber hindered by plane. The tuber gathered in the crops, through screening, diameter can be processed as finished product more than 1 centimetre, stem is planted in the just conduct less than 1 centimetre, packs, stores in the cool, breeds Rhizoma Pinelliae as the coming year.
3, the planting patterns of flue-cured tobacco:
Transplant: at the beginning of 5 months, sow after wheat harvest. Spacing in the rows 45-55 centimetre, sit and transplant under moisture film, stir, intertill in time, anti-mosaic disease. According to temperature height, little wind can be put and be maintained with temperature in the shed, amplify wind before drawing Seedling, adapt to external environment. Tobacco seedlings membrane envelope hole, the nitrogen-potassium compound fertilizer that respectively topdresses when transplanting 1 week 3 weeks (total of topdressing for twice nitrogen [N3-]5kg、K2O10 kg/acre).
The last ten-days period in May, spray first time green fragrant prestige 2,1 bag every mu, convert poison and disappear prevention mosaic disease. In the first tenday period of a month in June to the last ten-days period: take off film ridging, beat the bottom leaf that 1-2 sheet is worth without baking, every mu imposes potassium sulfate 10 jin, the green fragrant prestige 2 of spray second time, the 2 bags every mu medicaments converting preventing and treating weather speckle, wildfire, and Ex-all weeds water Wang Changshui. The last ten-days period in June are to the beginning of July: determine Topping Time according to soil fertility situation, take just flower to pinch, and chemical agent presses down bud, sprays the 3rd time green fragrant prestige 1, and 3 bags every mu, bottom flue-cured tobacco is mature on the whole, and prepares to toast.
Early July: baking the first premises foot leaf in time. Inferior leads stops roasting 7-10 days depending on Maturity of Flue-cured Tobacco, middle leaf maturation picking and roasting again after adopting roasting end. In the last ten-days period in August, cigarette classification is chosen on baking limit, limit, prepares to pay. JIUYUE last ten-days period, top, front and back leaf 4-6 sheet is disposable gathers.
4, the 2nd year, by the railway carriage or compartment switch of the plantation Rhizoma Pinelliae and plantation flue-cured tobacco in experiment plot, the railway carriage or compartment plantation Rhizoma Pinelliae of flue-cured tobacco is namely planted, the railway carriage or compartment plantation flue-cured tobacco of the plantation Rhizoma Pinelliae.
Rhizoma Pinelliae happiness is cloudy weak to sun, generally pure make the Rhizoma Pinelliae summer because of strong sun the Seedling that falls, the present invention because of the sheltering from heat or light of interplanting flue-cured tobacco, lower the temperature, moisturizing is moistened and is improved the effect of miniclimate, Seedling and the vigorous growth in summer of Rhizoma Pinelliae over summering, thus tuber is especially loose, improve Rhizoma Pinelliae yield and quality. And Rhizoma Pinelliae root exudates suppresses flue-cured tobacco soil-borne disease bacterium, reducing flue-cured tobacco incidence probability, in experiment plot, the sickness rate of flue-cured tobacco is substantially less than the plot that flue-cured tobacco is individually planted.
By above-mentioned interplanting plot continuous cropping 2 years. The yield data of contrast First Year and Second Year, result shows: the yield of Second Year flue-cured tobacco is the 102.47% of First Year, and the yield of Second Year flue-cured tobacco is the 98.23% of First Year; Better-than-average cigarette ratio is the 92.07% of First Year. By the flavor matter of flue-cured tobacco is detected, result shows: in the flue-cured tobacco in flue-cured tobacco comparison plot, flavor matter content great majority interplant the flue-cured tobacco in plot lower than flue-cured tobacco Radix Scrophulariae. The economic benefit in flue-cured tobacco Rhizoma Pinelliae interplanting plot more individually plants the plot of Nicotiana tabacum L., and economic benefit improves 21%.
