The invention relates to a salt and alkali decomposing biological bacterial fertilizer. The salt and alkali decomposing biological bacterial fertilizer is prepared through the following components by mass percentage: 65 to 80% of humic acid, 1 to 4% of EM bacteria, 5 to 15% of nitrogenous fertilizer, 5 to 11% of phosphatic fertilizer, and 5 to 11% of potash fertilizer. The salt and alkali decomposing biological bacterial fertilizer is prepared by the following steps: (1) mixing and uniformly agitating humic acid and EM bacteria, and fermenting for 72 to 96 hours at a temperature of 20 to 30 DEG C until the number of beneficial bactera in the mixture per kg is less than 20 million, thus obtaining a fermented material; and (2) adding nitrogenous fertilizer, phosphatic fertilizer and potash fertilizer to the fermented material obtained in the step (1); and uniformly mixing to obtain the salt and alkali decomposing biological bacterial fertilizer. The salt and alkali decomposing biological bacterial fertilizer is subjected to site-directed experience of three years in Ninghe County, Tianjin; the salt and alkali decomposing biological bacterial fertilizer added to the soil of which the pH (Power Of Hydrogen) is below 10 can decrease the pH of the soil by about 0.8 averagely each year; and after the salt and alkali decomposing biological bacterial fertilizer is used in three consecutive years, the pH of soil can reach a normal level, and as a result, the rate of survival of crops is greatly increased.

The invention relates to a preparation method of a semiconductor wafer cutting blade material. In the preparation method, high-purity green silicon carbide and black silicon carbide are adopted as raw materials, and a wafer cutting blade material is prepared through the steps of jaw crushing and sifting, wet ball milling classification, pickling, overflow size separation, concentrating and dewatering, drying, blending, fine screening and the like. Silicon carbide blade materials prepared through the method are most in equiareal shape and keep sharp edges and strong cutting power, can minimize TTV of a silicon wafer, and have strong adaptability to cutting fluid such as polyethylene glycol and the like because blade material particles have larger specific area and clean surfaces. Products crushed by a wet ball mill are most in equiareal shape, have high output, and can avoid excessive crushing. The preparation method of the invention can reach over 50% of rate of finished products, and products milled with the technology have more uniform size and distribution of particles, thereby better cutting effect to silicon wafers can be achieved.

The embodiment further provides acontrol system, the three-in-one purifying system is formed to perform differentiated purifying on water in a targeted manner, and dual objectives of control and collection can be achieved.

The invention discloses a winter greenhouse grafting method for English hawthorn 'Scarlet' planted in Beijing area. A wild hawthorn (C.pinatifida) is selected as a rootstock and the English hawthorn 'Scarlet' is selected as a scion. The winter greenhouse grafting method includes putting the rootstock in a pot and transplanting; waking the rootstock and the scion; cutting inside and connecting in greenhouse;and managing cleft and grafted seedlings. By the winter greenhouse grafting method, the survival rates of the English hawthorn 'Scarlet' are 96.1% and 98% respectively. After a winter growth, the sprout of the grafted seedlings reaches an average length of 70cm and a thickness of 4 mm. By greenhouse grafting, the winter pruned branches of the English hawthorn 'Scarlet' are fully utilized, the grafted period is increased and the growth time of the grafted seedlings is prolonged.
