Mixed seeding green manure dressing method for tobacco field

The invention discloses a mixed seeding green manure dressing method for a tobacco field. According to the method in the invention, mixed seeding is carried out on ryegrass and Chinese trumpet creeper in an equal ratio from the first ten days of September to the first ten days of October, wherein the seeding amounts of the ryegrass and Chinese trumpet creeper are 1.5-2.0kg/mu respectively, basic seedling amount is 70000-100000 plants/mu, 1500-2000kg of fresh samples are turned over and buried in per mu of soil with the depth of 10-20cm at the time of 40-45 days before flue-cured tobacco transplanting, and the pure nitrogen applying amount is reduced by 1.8-2.4kg/mu when tobacco seedlings are transplanted. The method comprises soaking seeds, seeding, fertilizer water management, turning over and burying and fertilizer application when the tobacco seedlings are transplanted. By using the method, the problems that when the fertilizer is singly applied for a long term, the carbon-nitrogen ratio in the tobacco field is reduced, nutrient is not balanced, effective fertilizer supplying capacity is weak, and the chemical components of tobacco leaves are inconsonant are solved. The method has the advantages that quick-action nutrient content, total bacterial count and nitrobacteria and actinomycetes quantities in current-season tobacco transplanting soil are obviously increased, the nutrient of the tobacco plants is consonant, the potassium-increasing base-reducing effect of the tobacco leaf is obvious, aroma quality is improved, and the benefit of tobacco planting is greatly improved. The method has good popularization value in the aspect of modifying the long-term continuous cropping tobacco field.

Method for restoring soil in farmland polluted by polycylic aromatic hydrocarbons by anionic-nonionic mixed surface active agent enhanced ryegrass and rhizospheric microorganisms

The invention discloses a method for restoring soil in a farmland polluted by polycylic aromatic hydrocarbons (PAHs) by anionic-nonionic mixed surface active agent enhanced ryegrass and rhizospheric microorganisms and belongs to the technical field of polluted soil restoration. The method comprises the following steps of (1) applying a low-concentration (30-150mg/kg) anionic-nonionic mixed surface active agent to the surface layer of PAHs polluted soil; (2) planting the ryegrass, harvesting plant bodies after the ryegrass grows for 40-60 days, and burning the plant bodies after the plant bodies are dried and transferred in a concentrative manner; (3) repeating the operation to clear away the PAHs in the polluted soil until the soil meets an environment safety standard. The method has the advantages that the low-dosage anionic-nonionic mixed surface active agent is adopted to elute the PAHs adsorbed on the soil in a solubilizing manner, so that the rhizospheric microorganisms can be promoted to degrade the PAHs, and the PAHs absorbed and accumulated by the plants can be improved; therefore, the efficiency for restoring the PAHs is improved. The method is simple in technology, low in cost, practical and safe.

Method for assisting in tailings restoration through ryegrass and planting ryegrass on restored land

A method for assisting in tailings restoration through ryegrass and planting the ryegrass on restored land includes the following steps that tailings is turned over by 18-22 cm and leveled; fresh ryegrass growing to the florescence are shorn into broken segments being 3-5 cm long so that ryegrass green manure can be formed; the ryegrass green manure is spread on the tailings land which is turned over and leveled, and the ryegrass green manure and the tailings are fully mixed evenly so that smooth planting land can be formed; ryegrass seeds are sown on the planting land. The planting method includes the steps that the seeds are processed and sown; the ryegrass is harvested regularly while stubble is left and the harvested ryegrass is returned to the field, 3-5 years after the ryegrass is planted, the whole ryegrass plants are recycled, the land is turned over, then, ridges are reconstructed for planting, and the plating method is repeated in this way. Due to the virtuous cycle that the planted ryegrass is returned to the field, the ecological environment can be continuously improved, and the landscape phenomenon of the tailings can be improved. The method has the advantages that operability is high and ecologically friendly and restoration cost is substantially reduced and the method is an important measure for ecological restoration of the tailings.

Fertilizer-saving method for increasing yield of double-crop rice through returning lolium perenne and straws to fields

The invention discloses a fertilizer-saving method for increasing yield of double-crop rice through returning lolium perenne and straws to fields and belongs to the technical field of fertilizer-saving and high-yield cultivation of agricultural production. The method comprises the following specific operating steps of subjecting fresh lolium perenne to turned-pressed field returning so as to replace part of nitrogen fertilizers during the growth of early rice, and returning straws of the early rice to the fields so as to replace part of the nitrogen fertilizers during the growth of late rice, thereby achieving the aims of soil fertility improving, nitrogen saving and high yield in a whole production cycle of the double-crop rice. According to the method, the problems of rice field cropping systems in the South of our country that the winter spare field area is enlarged, the rice field soil quality is lowered, the rice-production ecological cost is increased, the utilization rate of fertilizer is relatively low, and the like are solved, and the cultivation technique has the advantages that the yield of the double-crop rice is increased, the investment of chemical fertilizers is reduced, the utilization rate of fertilizer is increased, the soil tillage quality is improved, the yield is high, the nitrogen is saved, and the emission of N2O is reduced.
