Use Method: Applied to protection of soil cultivation: Solar heat & lime nitrogen grain method is used for soil sterilization, which can effectively control in variety of soil-borne disease s, insect damage and management of weed, as well as improve the physical and chemical function of the soil. Application Period The product is preferred to be used in June, July and August of relatively high temperature in North area, or in June, July, August and September after the plum rain season in South area when the application crops have been harvested and the fields (greenhouse or plastic tent) have been cleaned up. Besides, the product can also be used in other time if there is enough sunshine. After evenly scattering 60-80kg/mu (one mu equals to about 6.7 acres) of lime nitrogen grain, lime nitrogen grains are ploughed into the soil by rotary cultivator or by hands; the best depth is 20-30 cm in order to enlarge the contacted area of the arable soil to the greatest extent. Bedding: 30 cm height and 60-70 cm width; sealing: transparent film (or used film without breakage) is overlaid on the earth so as to completely enclose the surface of the soil; furrow irrigation: water is irrigated between furrows under the film until the surface of the furrows is fully moist, and irrigation is carried out again at the place where water leaks abundantly (It is unnecessary to irrigate water of豈??ten as long as the water content of the soil is over 70%); greenhouse sealing: breakages are repaired, there are no ventilation leakages in inlet, outlet and irrigation ditch, greenhouse is totally enclosed, and 15-20 days are needed to wait. It needs longer standby time when the temperature is low or a large amount of products are applied, while it needs shorter standby time when the temperature is high or less amount of products are applied. All in all, the processing time shall be 15-20 days usually. Film removal for air drying: 1-2 days of air ventilation or air drying is carried out after disinfection, sowing or seeds removal is executed thereafter (for the areas of no straw or wheat straw, organic fertilizers such as chicken manure can substitute straw or wheat straw to be used, or lime nitrogen grains can also be distributed directly for soil sterilization. The operating procedures are same as above.) For outdoor cropping: The product has the functions of alleviating in variety of soil-borne disease and insect damage, managing weeds, improving soil and acting as slow action nitrogen fertilizer. (1) Application Condition: the products can be used when the soil temperature is higher than 15℃.
Operation Procedure: During soil preparation period, 40-60 kilograms of lime nitrogen grain are scattered evenly for each mu (one mu equals to about 6.7 acres), and ploughed into the soil with the depth of 20-30 cm in order to enlarge the contacted area of the arable soil to the greatest extent. The next step is irrigation; the water content of the soil shall be over 70% (plastic mulching can be adopted for the areas in available conditions, which can make the temperature of the soil increase rapidly and have good moisturizing effect), when the temperature of the soil is above 15℃-20℃, it is after 20-30 days that the application crops are sowed, while the temperature of the soil is above 20℃, it is after 15-20 days that the application crops are sowed. Attention: Calcium and nitrogen proportion of fr豈??uit eggplant type vegetables should be paid attention to in order to avoid excess nutrient and over growth. The overwintering ovum of meloidogyne incognita will hatch out when the temperature is above 15℃. The meloidogyne incognita is lack of resistance during larva period, so it is the best time to use farm insecticide. Pesticide Effects （1）Soil Sterilization Preventing and curing soil-borne disease such as club root, stalk break, greensickness, seedling blight, etc., solving the problem of continuous cropping obstacle, and enhancing crops resistance; (2) Pest Control: Controlling the underground pest, effectively keeping and killing Meloidogyne incognita, as well as preventing and eliminating pest in paddy field; (3) Weed Control: Reducing weed problems and manual labor, and preventing the weed from getting nutrition. 。 2. Fertilizer Effects (1) Slow action nitrogenous fertilizer:
Lime nitrogen grain is a kind of slow action nitrogenous fertilizer, with the nitrogenous fertilizer effect of 3-4 months, which can reduce the application rates of other nitrogenous fertilizers and the nitrate content in farm products, and significantly increase output.。 Soil Improvement Improving soil aggregates, adjusting acid soil and making the soil suitable for crops growth. Accelerating the decomposition of organic materials, compost and decomposed manure effects, increasing the organic content of the soil, and improving land capability. 4、 Environmental Protection
Having the characteristics of natural fertilizer , with no residue, and no pollution to soil and water.
Removing stink of dung in livestock and poultry farms, and preventing environment pollution.
