Heilongjiang is a big agricultural province, the application of inorganic fertilizer for a long time, the soil quality drop, diseases and pests, the quality of the product of crops serious drop, serious impact on human health. To solve the change of agricultural production and now present situation, promote agriculture to free from contamination, pollution-free, high yield and good quality, low cost development direction. To use animal hair, cutin as raw materials production peptide-amino acid hydrolysis chelating older, and general fertilizer compared with unique characteristics and advantages, the production of peptide-amino acid liquid fertilizer can meet all the nutrition crop growth needs, easy to crop absorption. Application to crops, can improve the yield and improve quality, belongs to the non-toxic, non-polluting, non-pollution new type, efficient foliar fertilizers.By controling the diagonal protein hydrolysis time, hydrolysis temperature and add control agent decomposition of the conditions of the control, through improportining the traditional amino acid fertilizer production technology, to make the product of peptides and amino acid content to rationally proportion, to ensure products at the same time as the amino acid content contain 2~13 amino acids are connected to the activity of the small peptides proportion, a ratio of 22.6%-25.1%, and thus make peptides-amino acid liquid fertilizers to achieve the best effect.Rice seedbed spraying peptide-amino acid liquid fertilizer, can obviously promote seedlings hair root ability, increase root length, improve the seedling dry matter weight, among 500 times liquid concentration particularly, the root growth 0.48 cm long, dry weight of 0.02 g/strains increase, and increase root the extension of the rice and elongation, and promote the rice to the absorption rate n, and improve rice paddy rice rate, the rate, glue consistency, amylose content. Soybean seedling stage and two early flowering foliar spraying peptide-amino acid liquid fertilizer 500 times liquid photosynthetic rate increase by 1.07~2.27 mg. Co2/dm2. Hr can significantly improve the different development stages of soybean leaf chlorophyll content and soybean spraying 500 times liquid peptide-amino acid liquid fertilizer, can improve 0.88% crude protein, crude fat 0.08%. Peptide-amino acid liquid fertilizer of corn seed seedling, the chlorophyll content in seedling stage are higher,500 times liquid treatment in different periods of chlorophyll content are maintained at high levels, corn of photosynthetic rate increase rate between 12.2%~32.7%, corn leaves stomatal conductance growth between 16%~42%, improve maize plants body peroxidase activity, increase the number of corn, lateral root, root volume, root dry weight, increasing maize seedlings leaves area, root dry weight, stem to the dry weight, rootshoot ratio. Application of peptide-amino acids liquid fertilizer can increase rice, corn, rice production.500 times liquid processing the rice yield is the highest, about 5536.5 kg/hm2 and increase yield 11.1%, followed by 200 times liquid treatment yield by 8.6%; Application of peptide-amino acid liquid fertilizer 500 times liquid treatment corn increase rate is the highest, about 3.7% increase; The 1000 times liquid; the soybean peptide-amino acid liquid fertilizer, increase rate reached 16.07%; Shi into 500 times liquid peptide-amino acid treatment, increase rate reached 11.74%, soybean production optimal concentration for 500~1000 times liquid.
