Abstract
The present invention relates to a nutrient fluid formula for the mycorhiza floating seedling raising of the cured tobacco and an application method of the formula, which comprises three formulas of the formula at the sowing stage, the formula 30 days after the emergence of the seedling and the formula 45 days after the emergence of the seedling. Using the present invention to inoculate the mycorrhizal fungi for the tobacco seedling, during the transplanting, the mycorrhizal infection rate of one tobacco seedling is more than or equal to 20 percent and the mycorrhizal rooting rate of the tobacco seedling is more than or equal to 90 percent. The application method of the nutrient fluid of the present invention not only favors the infection of the mycorhizal fungi for the tobacco seedling, but also favors the application period and application quantity of the nutrient fluid being applicable to the nutrition requirements of the tobacco seedling; moreover, the seedling bed is free from salt harm and disease harm. At the same time, the concentration of the nutrient fluid of the present invention is only 50 percent to 60 percent of the concentration of the prior nutrient fluid that is used in the present production; the total consumption quantity of the fertilizer is dropped by 40 percent to 50 percent, thereby saving the resource and reducing the environmental pollution.
Description
Technical field
The present invention relates to modern agriculture production technical field, fertilizer field.Be primarily aimed in the floating seedling cultivation of fire-cured tobacco nutrient solution prescription and the application process thereof of production Mycorrhizal cigarette seedling.
Background technology
Flue-cured tobacco is the important economic crops of China, occupies critical role in Chinese national economy.The tobacco planting area was 1,572 ten thousand mu in 2006, and tax revenue reaches 2,900 hundred million yuan, occupied first of the national every profession and trade individual event tax revenue.In cured tobacco production, cultivating strong sprout is one of important step of cured tobacco production, also is the important measures that improve yield of flue-cured tobacco and quality.At present, floating seedlings is the main mode of flue-cured tobacco seedling-cultivating, accounts for 85% of cigarette seedling output.Floating seedlings is in greenhouse (booth), is carrier with matrix, and the intensive seedling production of nutrient is provided with nutrient solution.But in the floating seedlings practice, used nutrient solution concentration is higher, saltouts the harm tobacco seedling growth easily on the culture matrix surface; In addition, the nutrient solution of high concentration and greenhouse very easily cause the excessive growth of cigarette seedling, make the water content height of plant, and supporting tissue is undeveloped, easily brings out sprout term disease, and especially after transplanting the land for growing field crops, the resistance and the disease resistance of cigarette seedling are relatively poor, are subject to the influence of poor environment.
Inoculation arbuscular mycorrhizal fungi (abbreviation AM), infecting formation Mycorrhizal cigarette seedling is to improve cigarette seedling nutrition condition, increases the drought resisting resistance against diseases, improves the important means of cigarette seedling quality, and then is of value to raising yield of tobacco and quality.But AM is to the nutriment sensitivity, behind the cigarette seedling inoculation AM, available phosphorus 〉=20mg/kg in the matrix will be to AM infect the generation inhibitory action, so will production Mycorrhizal cigarette seedling, phosphorus and other nutrient concentrations must maintain reduced levels in the culture fluid, make the plain nutrition of phosphorus satisfy the needs of tobacco seedling growth and the eurythmy between nutritive element simultaneously again.The contradiction that solves between cigarette seedling mycorrhizal and the cigarette seedling nutrition supply just must have new nutrient solution prescription and supporting with it application process, but still do not have the special nutritional formula of liquid and the application process that are fit to cultivate Mycorrhizal cigarette seedling at present, do not have relevant research report both at home and abroad yet.So the special nutritional formula of liquid and the application process thereof of development Mycorrhizal cigarette seedling are pressing for of China's floating seedling cultivation of fire-cured tobacco intensification production.
Summary of the invention
The object of the present invention is to provide a kind of special nutritional formula of liquid and application process thereof that in floating seedling cultivation of fire-cured tobacco, is fit to the Mycorrhizal tobacco seedling growth, to solve the contradiction between cigarette seedling mycorrhizal and tobacco seedling growth, the nutrition supply, improve cigarette seedling overall qualities, guarantee to have higher drought resistance and disease resistance behind the cigarette transplantation of seedlings land for growing field crops.
The special nutritional formula of liquid of flue-cured tobacco fungus rooting floating raise seedling is formed (table 1) by macroelement solution, trace element solution, EDTA-iron salt solutions 3 parts.
Table 1. flue-cured tobacco fungus rooting floating raise seedling different times special nutritional formula of liquid (ml/L)
