Description

Technical Field

[0001] The present invention relates to the technical field of fertilizers, and particularly to a composition containing biostimulants and its application. Background Art

[0002] Fertilizers can be classified into organic fertilizers, inorganic fertilizers, microbial fertilizers, etc. according to their components and sources; at present, there are problems with unreasonable selection of fertilizer types in the process of lettuce cultivation. For example, excessive application of nitrogen fertilizer: Many growers apply excessive nitrogen fertilizer during lettuce cultivation while neglecting the combined use of phosphorus and potassium fertilizers, which can lead to low lettuce yields, poor quality, and even diseases such as "dry heartburn"; neglect of medium and trace elements: Lettuce requires a variety of medium and trace elements (such as calcium, boron, etc.) during growth, but many growers only focus on nitrogen, phosphorus, and potassium fertilizers and neglect the supplementation of these elements, which easily leads to poor growth of lettuce; applying unrotted organic fertilizers can cause pests and diseases and affect lettuce growth. Therefore, providing a fertilizer that simultaneously contains organic fertilizers, inorganic fertilizers, trace elements, and biostimulants to improve the yield and quality of lettuce is of great significance to the field of fertilizer types and lettuce growers.

[0053] By mass, the raw materials are mixed evenly to obtain the fertilizer.

[0054] Example 2

[0055] The difference from Example 1 is only that, by mass, the raw materials of the composition containing a biostimulant are composed of 2 parts of sodium humate, 1 part of seaweed extract, and 1 part of Gentiana scabra Bunge waste extract.

[0056] Example 3

[0057] The difference from Example 1 is only that, by mass parts, the raw materials of the composition containing the biostimulant are composed of 1 part of sodium humate, 1 part of seaweed extract, and 1 part of gentian waste extract.

[0058] Comparative Example 1

[0059] The difference from Example 1 is only that the addition of gentian waste extract is omitted.

[0060] Comparative Example 2

[0061] The difference from Example 1 is only that the addition of the composition containing the biostimulant is omitted.

[0062] The effects of the fertilizers prepared in Examples 1 - 3 and Comparative Examples 1 - 2 were verified as follows:

[0063] Experiment location: A vegetable greenhouse in Jiamusi City, Heilongjiang Province;

[0064] Experiment variety: Heading lettuce Green Saint 1106;

[0065] Experiment method:

[0066] The experimental plot was divided into 6 plots, each plot having an area of about 0.2 mu. Among them, the fertilizers prepared in Examples 1 - 3 and Comparative Examples 1 - 2 were applied to the 1st - 5th plots respectively, and the corresponding plots were marked as Example 1, Example 2, Example 3, Comparative Example 1, and Comparative Example 2; The 6th plot was applied with compound fertilizer (N∶P∶K = 15∶10∶10), and the corresponding plot was marked as the control group. The fertilizers of the above 6 plots were all used as base fertilizers, and the application rate was 50 kg / mu. When applying the base fertilizer, the soil surface layer was plowed, and the plowing depth was 15 - 20 cm. Other planting management methods such as planting density, irrigation, and pesticide application were carried out according to the local conventional management methods. When harvesting the lettuce, the lettuce yield (kg / mu) and the soluble solids (%) in the lettuce, soluble sugar content (mg·g -1 ), soluble protein content (mg·g -1 ·FW), and VC content (mg·100g -1 ) were counted, and the results were tabulated in Table 1. The soluble solids content was measured by the refractometer method, the soluble sugar content was measured by the copper reduction iodometric method, the soluble protein content was measured by the Coomassie brilliant blue staining method, and the vitamin C content was measured by the 2,6 - dichlorophenol indophenol titration method. The above detection methods and the lettuce yield statistics method are all conventional technical means in the field and are not the focus of protection of this invention patent, so they will not be elaborated here.
