A food container formed by compressing a mixed material composed of unboiled bamboo fibers and mixed fibers prepared by mixing unboiled grass family vegetable fibers and unboiled legume family vegetable fibers such as lespedeza fibers. A food container formed by compressing a mixed material composed of the above mixed material, a small amount of water repellent, and a small amount of paper strength additive.

The invention relates to a paddy field weeding composition which takes allylene oxadiazon, pretilachlor and oxyfluorfen as active ingredients. The composition can be prepared into an emulsion in water or a film-forming oil solution, and is used for preventing and treating annual grass family and broad leaf weeds in paddy fields.

The invention relates to a production method of carboxymethyl lignin used as an additive for the negative electrode of a lead-acid storage battery. The production method comprises the following steps: firstly, preparing materials; secondly, dissolving lignin; thirdly, alkalizing lignin; fourthly, etherifying the alkalized lignin; and fifthly, forming the carboxymethyl lignin. According to the carboxymethyl lignin prepared by the method, as the carboxyl content of lignin produced by grass families is high, carboxymethyl content is high after carboxymethylation and the water solubility is good; the purity of lignin extracted by organic solvent is high, lignin is dissolved in an organic solvent used as a reaction medium and can be subjected to homogeneous reaction, the reaction is complete and uniform, the degree of substitution of the carboxymethyl is improved, the solvent can be recycled and the production cost is reduced.

The invention relates to herbicide which includes two active components of azole-adizon and benzyl methyl. The components have the weight contents that: azole-adizon is 0.01-15 percent, benzyl methyl is 5-50 percent, general pesticide adjuvant is 1-20 percent, and the rest is fillings. The invention can be mainly used to remove the ruderal for grass family crops, can have obvious spectrum-enlarging and effect-increasing function, and have stronger weeding activity, can kill a plurality of broadleaf ruderal simultaneously, can reduce the dosage and the cost, can amend the environment and improve the food safety, and suitable for the conditions of China.

The invention discloses a sweet potato high-yield cultivation technology. The invention relates to the technical field of agricultural cultivation, and especially relates to a sweet potato cultivation method. With the technology provided by the invention, sweet potato yield can be improved. The sweet potato high-yield cultivation technology is characterized in comprising the following steps: 1, deep plowing and ridging are carried out, wherein sweet potato is an underground tuberous root crop, the growth and development of which needs deep plowing and ridging; 2, scientific fertilization is carried, wherein sweet potato yield is high, root system is developed, and fertilizer absorption capacity is high; in average, the production of every 500kg of fresh sweet potato needs 1.86kg of pure nitrogen, 0.86kg of phosphorus pentoxide and 3.74kg of potassium oxide to be absorbed from soil; 3, seedling inspection and replanting are carried out in time after sweet potato planting, such that complete and vigorous seedlings are ensured; seedling inspection and replanting should be carried out 5-6 days after planting; and 4, crop rotation and alternation are carried out, while a resistant variety is selected according to local conditions, crop rotation and alternation can be carried out once 3-5 years with grass family crops such as maize and wheat, such that pest and disease occurrence and damage can be reduced.
