The invention discloses methods for producing fulvic acid salt, fulvic acid salt water-soluble fertilizers and aquatic nutrient solution from alcohol waste liquid from waste molasses. The method for producing the fulvic acid salt from the alcohol waste liquid from the waste molasses includes steps of 1), carrying out acidification reaction, to be more specific, adding the alcohol waste liquid from the waste molasses into sulfuric acid solution with the concentration of 30-55%, carrying out stirring acidification reaction, then adding potassium salt into first reaction products, dissolving the potassium salt and continuously stirring the potassium salt and the first reaction products until reaction is completely carried out to obtain products with fulvic acid; 2), carrying out salt forming reaction, to be more specific, adding prepared alkaline solution into the products, obtained at the step 1), with the fulvic acid, carrying out stirring reaction until the products are alkalized and salt is formed, and then cooling the salt until the temperature of the salt reaches the room temperature so as to obtain the fulvic acid salt. The fulvic acid salt water-soluble fertilizers and the aquatic nutrient solution further can be obtained from the fulvic acid salt. The methods have the advantages that the problems of pollution on natural environments and disruption of ecological balance due to discharge of waste liquid obtained after alcohol is produced from existing waste molasses can be solved by the aid of the methods, and excellent economic benefits further can be created.

The invention relates to methods for cultivating high-quality fresh-eating amygdalus persica L., in particular to a method for cultivating amygdalus persica L. in a high-altitude area. The method comprises the steps of selecting local stock varieties with strong stress resistance, cultivating seedlings for 2-3 years according to a conventional method, and selecting robust plants which are 0.8-1 m in height and 1.5-2 cm in ground diameter from the seedlings as transplanting seedlings of amygdalus persica L.; then transplanting the seedlings to the high-altitude area with the altitude of 3,000 m or above according to the planting density that the plant spacing is 1 m, and the row spacing is 4 m. According to the method, unique natural environment advantages and regional advantages of the high-altitude area of Tibet are utilized, and through reasonable close planting, high yield, optimal production and special production are achieved. Besides, through out-of-season supply, the gap of the market is filled up, the price of fresh fruits is high, and the economic benefit is obvious.

The invention discloses a soil insect control method for vegetable planting. The method comprises the steps that multi-stroma cordyceps taishanensis conidial powder is inoculated to insects, then, insects dead due to infection are ground into powder, and the insect powder is regularly buried near the roots of vegetables. The single strain is adopted, the competitive inhibition effect among multiple strains is lowered in the culture process, and the strain and sporophore culture time is greatly shortened; due to the fact that the survival ability of the bacterial strain spores obtained after polypides are infected in the natural environment is enhanced, and the storage requirement is lowered; during application, the landfilling method is adopted, the persistent valid time of multi-stroma cordyceps taishanensi in soil can be longer, and the effect of controlling shallow soil insect pest is remarkably enhanced.

The invention discloses a packing method for encapsulated food, particularly relates to a packing method for liquid canned food.. The technological process is as follows: a proper amount of assistant (sugar or salt) is added to vacuum-encapsulated liquid food; after vacuum treatment, the liquid food is loaded in a vacuum material concentrating chamber of a gas-liquid separated type spraying tank through a valve port; and interlayer air is drained and inert gas is pressed in to form internal pressure. The method has the characteristic that an only-outlet-no-inlet packing method is adopted in a natural environment, so that external air and pollutants can not enter into the packing container, thereby achieving the purposes of repeated opening and long-time fresh-keeping.
