Abstract
The invention discloses a method for preparing a flue-cured tobacco float breeding matrix by using wheat straws and a flue-cured tobacco float breeding nutrient solution. The method comprises the following steps of: pre-treating the wheat straws, and performing mixed piling-up fermentation treatment on the pre-treated wheat straws and pig manure, or chicken manure, lime, soil and the like so as to prepare the flue-cured tobacco breeding matrix, wherein the raw materials replace non-renewable peat, so the effects of low cost, high quality and sources; the piling-up fermentation temperature is over 60 DEG C, and the piling-up fermentation can last for more than 15 days, so that pathogenic bacteria can be killed effectively, and the disease and pest spreading can be prevented; the obtained breeding matrix is loose and porous, beneficial to growth of root systems of tobacco seedlings and high in water and fertilizer keeping capacity; the nutrient solution matched with the flue-cured tobacco float breeding matrix is complete in nutrition, and reasonable in ratio, saves fertilizers, and reduces the cost; growth conditions and agricultural indexes of the tobacco seedlings bred by using the matrix and the nutrient solution disclosed by the invention are equal to those of tobacco seedlings bred by using a peat matrix.
Description
Technical field
The present invention relates to cultivation technique without soil field, particularly relate to a kind of method and nutritive medium that utilizes wheat stalk to prepare floating seedling cultivation substrate for flue-cured tobacco.
Background technology
Flue-cured tobacco is one of important cash crop of China, extensively plants in southwests such as cloud, expensive, river, Chongqings.In cured tobacco production, cultivating strong sprout is one of important step of cured tobacco production, is also the important measures that improve yield of flue-cured tobacco and quality.At present, floating seedlings is the major way of flue-cured tobacco seedling-cultivating, accounts for 85% of cigarette seedling turnout.Peat is the major ingredient of levitating seed-cultivating interstitial substance.But exploitation peat cost is high, environmental pollution weight, and peat resource-constrained.In making the process of Friendly tobacco seedling raising medium, the substitute materials of finding peat is the vital task that guarantees China's flue-cured tobacco Sustainable development.
Southwest mostly is slope and ploughs, and plot is little, and the gradient is steep, and wheat stalk is difficult to realize mechanize and turns over; Simultaneously, the succeeding crop sowings (transplanting) such as the harvesting time of local wheat and flue-cured tobacco, Ipomoea batatas, corn are overlapping, in addition straw nutrient content is low, and the phenomenon of soil microorganisms and crop contention nutrient easily occurs straw direct returning to farmland, affects succeeding crop and grows.At present, on-site incineration wheat stalk is the very general phenomenon in southwest, not only wastes a large amount of organic matters and nutrients resource, and causes serious atmospheric pollution.Therefore, in agriculture production, urgently economical, easy, harmless treatment and recycling wheat stalk effectively.
The main component of wheat stalk is Mierocrystalline cellulose, hemicellulose and xylogen, and a small amount of nitrogen, phosphorus, potassium, calcium, magnesium, silicon etc.The wheat stalk becoming thoroughly decomposed can substitute peat, as Friendly tobacco seedling raising medium.But with wheat stalk, do the essential problem that solves microorganism and cigarette seedling contention nutrient of Friendly tobacco seedling raising medium, there is no at present correlative study report.
In floating seedling cultivation of fire-cured tobacco process, except seedling medium, also need nutritive medium that nutrient is provided.Flue-cured tobacco after planting, generally needs within 15-20 days, just can emerge, and early growth is extremely slow, and nutrition absorption is few; The just ramp of emerging about 40 days, nutrition absorption speed increases.At cigarette seedling different times, need the composition of nutrient and form also different.But the nutritive medium that floating seedling cultivation of fire-cured tobacco is used at present, does not consider the difference needs of cigarette seedling different times to nutrient, all uses the changeless nutritive medium of composition and concentration, can not meet the physiological requirements of cigarette seedling to nutrient.There is no at present the research report of nutritive liquid for floating seedling growth of tobacco stage by stage.
Summary of the invention
The object of the present invention is to provide a kind of method of utilizing wheat stalk to prepare floating seedling cultivation substrate for flue-cured tobacco.The method, in treating processes, realizes high-temperature sterilization, and quick composting substitutes peat with the wheat stalk becoming thoroughly decomposed, and produces the matrix that is applicable to flue-cured tobacco seedling-cultivating, realizes through the following steps successively:
(1) pulverize wheat stalk to 3mm, in flue-cured tobacco seedling greenhouse, by wheat stalk (water content is less than 10%), water, pig manure or chicken manure (water content 50%～60%), lime, 100:60:25 ~ 30 in mass ratio: 1 mixes, with agricultural plastic film, cover, bank up 30 days, each turnings in the 7th, 15,20,25 days of banking up 1 time, obtain wheat stalk handled thing;
(2) will glue the topsoil gong of earth ~ light earth air-dry, cross 1.5 ~ 2mm sieve, add water-wet soil to 65%～70% of maxmun field capacity, firmly pinch agglomerating, lose the state scattering on the ground, then by wetting soil: wheat stalk handled thing quality mixes than 1:2.2 ~ 2.8, be stacked in flue-cured tobacco seedling greenhouse, in each turnings in the 15th, 30,45 days of banking up once, bank up and within 60 days, obtain floating seedling cultivation substrate for flue-cured tobacco.
Step (2) was banked up after 60 days, can prepare the admixing medical solutions of blue or green withered spirit and early frost spirit, by piling glove: admixing medical solutions mass ratio 50:1 mixes, and obtains floating seedling cultivation substrate for flue-cured tobacco.
The compound method of blue or green withered spirit and early frost spirit admixing medical solutions is: first with 20% blue or green withered spirit, be watered 500 times of dilutions, 25% early frost spirit is watered 500 times of dilutions, and then 1:1 mixes by volume.
Another object of the present invention is to provide a kind of nutritive liquid for floating seedling growth of tobacco, its component and content are as follows:
Nutritive medium A: add 0.2g ammonium nitrate and 0.13g potassium primary phosphate gained mixed solution by every 1L water;
Nutritive medium B: add 2.0g ammonium nitrate, 1.34g potassium primary phosphate, 0.14g potassium sulfate and 0.5mL trace element solution gained mixed solution by every 1L water;
Nutritive medium C: add 6.0g ammonium nitrate, 4.02g potassium primary phosphate, 0.42g potassium sulfate and 1.5mL trace element solution gained mixed solution by every 1L water;
Described in nutritive medium B and nutritive medium C, trace element solution is for to add 0.5g borax, 1g zinc sulfate, 1.5g ferrous sulfate and 0.25g copper sulfate gained mixed solution by every 1L water.
The using method of above-mentioned nutritive liquid for floating seedling growth of tobacco is: during sowing, nutritive medium A is added in nursery pond; After planting the 30th day, change nutritive medium B; After planting the 45th day, change nutritive medium C, until transplant.Depth Nutrient Solution is 6 ~ 8cm.
advantage of the present invention is:
Pre-treatment wheat stalk of the present invention, for the preparation of Friendly tobacco seedling raising medium, can replace non-renewable peat, good and cheap, economizes on resources; The leavening temperature of banking up surpasses 60 ℃, continues more than 15 days, can effectively kill pathogenic bacteria control disease spread; Gained seedling medium is not only loose porous, useful cigarette seedling root growth, and also preserve moisture and fertility power is strong; The nutritive medium nutrient matching is complete, and ratio is reasonable, saves fertilizer, reduces costs, and the cigarette seedling that cigarette seedling growing way and agronomic trait and peat growing medium are cultivated is suitable.
