The invention provides a method for quickly desalting, dealkalizing and ploughing a soda saline-alkali paddy field. The method comprises the following steps of: in the rice field after rice harvest in autumn, turning up the soil by using a big plough in autumn after base fertilizer is applied; sunning the upturned soil; rotating the soil in a dry mode in spring of the next year; ridging and soaking; leveling the field by using a thick rake until slurry is settled; and transplanting. In the method, spring soil turnup is replaced by autumn soil turnup; autumn soil turnup is combined with springsoil rotation; advantages of two tillage methods of rotary tillage and autumn soil turnup are utilized, advantages are absorbed and disadvantages are complemented, advantages are utilized and disadvantages are avoided, soil fertility is adjusted, and soil application and improvement are taken into consideration; and water resource is saved, saline and alkali are removed quickly, the soil structure is optimized, fragile ecological environment is improved, high yield, stable production and sustained development of rice in saline-alkali adverse situation are promoted. Rice is planted in the sodasaline-alkali land by the method, so the method is simple and easy in operation and convenient to popularize, labor and time are saved, production input cost is low, yield is increased obviously, repair of the fragile ecological environment is facilitated, and income of farmers is increased.

The invention discloses a medicine for preventing fish parasitic crustacean diseases, a preparation method and an application thereof. The method comprises the following steps that pyridaben with masspercentage of between 5 and 30 percent and a surface active agent with mass percentage of between 5 and 25 percent are mixed; after the mixture is stirred for 25 to 35 minutes at a temperature of between 25 and 35 DEG C under 280-320rpm, a 45 to 90 percent solvent is added into the mixture to be stirred for 25 to 35 minutes to prepare the medicine for preventing the fish parasitic crustacean diseases. The method successfully applies pyridaben to the preparation of the medicine for preventing fish parasitic crustacean diseases for the first time. The medicine for preventing fish parasitic crustacean diseases has simple preparation process and easy operation, good effect, small dosage, long lasting period, safe for fish and non-pollution to ecological environment.

The invention discloses a rice field milk vetch sowing-free circulation seed reserving method. The method comprises the following steps that after milk vetch seeds are mechanically harvested in early and mid May, smashed milk vetch straws are evenly spread in a rice field, irrigation is conducted, a drainage outlet is blocked (so as to prevent milk vetch seeds reserved in the rice field from flowing away along with water), biodegradation is conducted for five to ten days, dry farming is conducted to achieve single-season rice transplantation or single-season rice no-tillage direct sowing, the single-season rice is irrigated by shallow water at the early growth stage, water falling and field drying are conducted at the rice milk-ripe stage, the single-season rice is harvested from the mid and late September to early October, high stubbles of straws are reserved to be returned to the field, or removed from the seed reserving field within one to three days, ditching or ditch cleaning is conducted, and no water is reserved in the field in sunny days or accumulated in rainy days; routine management of milk vetch planting is conducted, and circulation operations of farming work such as milk vetch seed mechanical collection and single-season rice sowing are conducted in the next early and mid May. The rice field milk vetch sowing-free circulation seed reserving method solves the problems that at present, field abandonment is general in winter in the single-season rice field, and rice field green manure milk vetch seeds are scarce, and relieves milk vetch seed shortage, increases milk vetch seed reserve, and achieves the effect of returning milk vetch straws for fertilizing rice field soil.

The invention discloses a method for planting anoectochilus formosanus in the northern area. The method comprises the following steps: (1) woodland selection, (2) seedling selection, (3) seedbed preparation, wherein the northern area with the temperature in spring, summer and autumn ranging from 15 DEG C to 30 DEG C is selected as the cultivation field, soil under chestnut trees is selected, soil texture is required to be loose, breathable and good in moisture retention, the matrix on the ridge surface is formed by adopting and evenly stirring and mixing 1 / 2-2 / 3 of organic fertilizer and 1 / 3-1 / 2 of under-wood fine soil humus, before plantation, spraying and sterilizing are carried out through carbendazim or thiophanate, plastic films cover the matrix for 2-3 days and then are uncovered, and the matrix is prepared for use, (4) transplantation, (5) management after plantation, and (6) harvest. According to the method, a complete set of the technology for planting the anoectochilus formosanus under woods in the northern area is formed. The wild environment is imitated, local natural products are explored and utilized for mixing preparation to form the matrix for transplantation, and therefore the production cost is low; the cultivation technology for improving the plantation survival rate of the anoectochilus formosanus is formed, and therefore the stable yield is achieved easily; by the adoption of the method, the anoectochilus formosanus grows normally, and the net weight of a single plant is increased.

The invention discloses a method for determining the optimal nozzle size of a tight oil volume fracturing well, comprising the following steps: S1: obtaining basic data of a target well; S2: determining a reasonable nozzle size of the target well; S3: calculating different reasonable nozzle sizes Under the liquid production index and oil production index, the nozzle size corresponding to the maximum liquid production index and oil production index is the optimal nozzle size; S4: Calculate the declining production; S5: Calculate the cumulative liquid production under different reasonable nozzle sizes; S6 : Calculate the cumulative oil production under a single nozzle size; S7: Determine the size of the combination of nozzles; S8: Calculate the oil production index under different combination sizes of nozzles; S9: Calculate the cumulative oil production under different combination sizes of nozzles, cumulative oil production The combination size of the nozzle corresponding to the highest is the optimal combination size of the nozzle. The invention makes full use of the natural elastic energy of the oil reservoir, delays the decline period, makes more oil recovery and greater ultimate recovery ratio, and provides technical support for the efficient development of tight oil reservoirs.

The invention discloses a special fertilizer for the integration of water and fertilizer for corn and an application method thereof. The special fertilizer for the integration of water and fertilizer includes a special fertilizer for emergence, a special fertilizer for the ear stage, and a special fertilizer for the flowering and grain stage; the three special fertilizers all include the following components: Urea, diammonium phosphate, potassium chloride, zinc chelate, boric acid, manganese chelate, magnesium chelate, iron chelate, copper chelate.
