The invention discloses a spin milling type multifunctional machine for deeply ploughing and crushing ridges, which is based on a tractor. A hydraulic mechanism and a linking spin milling drill bit device or a cultivation component is arranged on a rear frame of the tractor; the linking spin milling drill bit device is provided with one or more drill bit shafts; spiral hinges are arranged on the drill bit shafts and provided with apical teeth; the linking spin milling drill bit device is provided with a device for preventing a straw from being wound; the hydraulic mechanism drives a spin milling drill bit to move up and down; and a gearbox drives the spin milling drill bit by a connecting rod and a gear. According to the spin milling type multifunctional machine, the drill bit enters into soil and then vertically cuts, spin mills and crushes the soil and ensures that the soil is automatically suspended to form the ridges; the soil crushing section of the crushed ridge is T-shaped; the lower part of the compacted soil on the ground is in a U-shaped groove, so that the whole layer of the soil is in a loosing state during cultivation; and in addition, the invention plays roles of covering and replacing the soil, increases an active layer, improves the capabilities of preserving moisture and fertility and the permeability of the soil, benefits the utilization of deep growing of the crop root system to water and fertilizer, relatively reduces pests and weeds and ensures that the crop is easy to obtain high and stable yield.

The invention discloses a method for planting dryland crops. A rotavator is utilized to deeply loosen and crash the soil in furrows so as to crash the loose soil in a cultivated layer and plough sole and make a portion of foreign soil in the plough sole rise up to be naturally mixed with the soil in the cultivated layer for forming furrows and ridges. The ridges are trapezoidal. Each furrow is 25to 30 cm in width and 80 to 100 cm in depth with loose soil distributed in a T shape, and each loose ridge can be 70 to 80 cm in width and 20 to 25 cm in height; or, each furrow is 50 cm in width and60 to 70 cm in depth, and each ridge is 90 cm in width and 20 cm in height. Crops can be planted right after soil is loosened by the rotavator and formed into ridges. Spacing and furrow depth can be determined according to the planting requirements of different crops. By using the method of the invention, soil in the whole cultivated layer is in a loose state, and foreign soil can be improved during deep rotary tillage, therefore, the water and fertilizer retaining ability and the permeability of the soil are enhanced. The invention has the advantages of helping crops root deeply and utilize water and fertilizer, relatively reducing diseases and weeds, and greatly increasing the yield of crops (usually over 20%, and a maximum of over 100%).

This invention relates to a soil conditioner, especial a nutritional soil conditioner to be used specially for saline lands. Its components and their weight percentage is that desulfuration offal 30-50%, accelerator 10-15%, straw powder 10-30%, furfurol dregs 10-20% and organic fertile 10-12%. First straw powder and organic fertile are shattered by crusher with its grade size less than 2mm, and then mixed homogeneously with desulfuration offal, furfurol dregs, accelerator, then conducted magnetization with magnetizing machine and dried by drying machine, and then sizing and packaging. This invention can improve physical and chemical characteristic of the soil, inhibit the increase of salt, neutralize alky of the soil simultaneously, and can also provide affluent nutrient for crops.

The invention relates to a pool with a multi-layer structure and a building method of the pool. The bottom of the pool is arranged under the ground, a part which extends from the highest place of an excavation side of a side wall of the pool to the ground at one non-excavation side is provided with a top press region; an underground water discharge layer is arranged under the bottom surface of the pool, and a base cushion layer, a seepage-proof layer and a protecting layer, which are connected with one another into a whole, are sequentially arranged on the underground water discharge layer, the excavation side of the side wall of the pool and the top press region; and a ring-shaped underground water discharge blind drain is arranged under the underground water discharge layer along the lowest place of the excavation side of the side wall of the pool, at least one linear underground water discharge blind drain is arranged under the excavation side at the bottom of the pool, two ends of the linear underground water discharge blind drains are communicated with the ring-shaped underground water discharge blind drain, and a water outlet of the ring-shaped underground water discharge blind drain is connected with an underground water discharge pipe. The pool is ingenious in conception, is resalable in design, and has the advantages of being high in foundation deformation resistance, high in stability, good in water-storing and seepage-proof effect, low in project cost, long in the facility service life, wide in application range, simple in construction and the like.

The invention relates to a water-retaining agent and a preparation method, specifically to a water-retaining agent containing aloe gel and a preparation method thereof. The water-retaining agent is prepared from the following raw materials (by weight): 3-10 parts of aloe gel, 10-20 parts of humus, 50-70 parts of plant fiber, 10-20 parts of starch, 2-3 parts of ferric sulfate, 25-35 parts of acrylic acid, 7-15 parts of acrylamide, and 80-120 parts of 27-37% aqueous alkali. The water-retaining agent provided by the invention is environment-friendly, has advantages of simple process and strong water retaining capacity, and can provide nutrients essential for growth of plants, and has effects of fixing sand and preserving water and improving soil.

The invention relates to a high-efficiency and environment-friendly water retention agent with zeolite as the main raw material and a preparation method thereof. The parts by weight of raw material components are: 60-80 parts of zeolite powder, 15-35 parts of composite additives, and 2-10 parts of superabsorbent resin. The water-retaining agent has strong water-absorbing and water-releasing functions, and the water-retaining agent has good gel after absorbing water. The water-retaining agent not only has good water-retaining performance, but also has simple preparation process, low cost, environmental protection and no pollution, and is beneficial to industrial production.

The invention provides an organotrophic saline soil conditioner. The conditioner is prepared from the following components in percentage by weight: 50%-70% of livestock and poultry wastes, 1%-5% of accelerator, 10%-30% of straw, 8%-15% of powdered rock phosphate or calcium superphosphate, 3%-8% of gypsum and 1%-8% of modifier. When the soil conditioner is applied in the saline alkali soil, the volume weight of the soil can be reduced, the porosity is increased, the velocity of permeability is improved, the water retention capacity is enhanced, the pH value is significantly reduced and the structure of the soil is greatly improved. The application of the soil conditioner promotes the improvement in phosphorus and nitrogen levels and thus the yields of crops are further increased.
