Description

A kind of organic pelletized preparation of lettuce seeds and its preparation method

technical field

The invention discloses an organic pelletized preparation of lettuce.

Background technique

In the prior art, when planting lettuce, various accidents are often encountered. During the growth process, the initial management is not in place, and the pests and diseases occur seriously, so that the pesticide residues are seriously affected, and the safe eating effect is poor; biogas slurry is widely used by people. It is a well-known bio-organic fertilizer with both quick-acting and long-acting effects; biogas slurry is rich in nitrogen, phosphorus, potassium, various amino acids, vitamins, proteins, gibberellin, auxins, sugars, nucleic acids and antibiotics etc., as well as active resistant substances such as butyric acid, indole acetic acid, and vitamin B12; therefore, it has a dual role of promoting crop growth and controlling disease occurrence.

Seed granulation processing is to use seed granulation equipment to coat the active ingredients and some auxiliary materials on the seeds in an orderly manner to realize the enlargement and regularization of the seed shape; to achieve plant protection before sowing, to treat both diseases and insect pests, and to promote crop growth; The seed fertilizer on the outer layer of pelletized seeds can ensure that the seedlings can get the necessary nutrients at the early stage, and the insecticides and fungicides in it have good control effects on underground pests and seedling diseases; improve the efficacy; pelletization can It is carried out in layers, which can isolate the substances that affect each other, so as to improve the efficacy of the medicine without harming the vitality of the seeds; enhance the stress resistance of the improved seeds; various substances can be added to the seed pelleting treatment for specific seed treatment , Improve the drought resistance, cold resistance, waterlogging resistance and herbicide resistance of seeds.

However, the insecticides or fungicides used in pelleted seeds are highly toxic, have a certain impact on the germination rate of seeds, and may cause pollution to the environment and endanger the safety of humans and animals; at present, the technical scheme of seed pelletization: first, After the seeds are cleaned, the impurities, dust and unfulfilled seeds are removed; secondly, the cleaned and processed seeds are added to the pelletizing equipment for pelletizing operation. During the operation process, according to the procedures set by the equipment, Add various pelletizing materials, such as pesticides, fertilizers, growth regulators, water-retaining agents, fertilizer-retaining agents, binders, powders, colorants, etc., in sequence according to the pelletizing formula ratio. According to different pelletizing purposes, Formulate different coating agents for pelletization; after the pelletization operation is completed, the pelletized seeds enter the drying stage, which can be dried mechanically and naturally; finally, they are screened and packaged; it is difficult to achieve complete, uniform and strong seedlings during planting , so there is an urgent need for pollution-free pelleting; however, although there are various coating agents, these coating agents are not only expensive, but also difficult to obtain good results when used to pelletize cabbage seeds , can't maintain effective cracking property, slow release and high germination rate after sowing for a long time; therefore, pelletized seeds aiming at the characteristics of organic lettuce seeds (including the characteristics of the seeds themselves and the adapted climate characteristics, etc.) are very much needed.
