Special multifunctional soil conditioning type protected area commercial crop fertilizer as well as preparation method and application thereof

Abstract

The invention relates to a special multifunctional soil conditioning type protected area commercial crop fertilizer as well as a preparation method and application thereof. The protected area commercial crop fertilizer provided by the invention comprises a basic fertilizer, medium / trace elements and a soil conditioning agent, wherein the soil conditioning agent comprises a mixture of grondverbeteraar, an alga extract and humic acid and one of fulvic acid and a fulvic acid salt; the weight ratio of the grondverbeteraar to the alga extract ranges from (1:4) to (9:5). According to the special fertilizer provided by the invention, the soil porosity of protected area planting can be remarkably increased, the soil bulk density can be reduced, and soil structures can be improved; in addition, theyield of vegetables is increased, the contents of nutrient substances in the vegetables can be increased, and the quality of a vegetable product can be improved.

Description

technical field [0001] The invention relates to the technical field of special fertilizer for crops, in particular to a multifunctional soil conditioning type special fertilizer for economic crops in protected areas, a preparation method and application thereof. Background technique [0002] In agricultural production, the production of vegetables in protected areas is a fast-paced production process with high input and output, fast crop rotation, more pest control, and frequent adjustment of soil fertility. The quality and fertility of the soil determine whether the production of protected vegetables can be achieved. The key to continuity and attainment of desired requirements. However, in the current production process of cash crops, farmers are limited by their own conditions, such as: lack of knowledge on fertilizer application, lack of attention to scientific fertilization, or improper fertilization methods, and lack of scientific production management. Ideal economic ...

AI Technical Summary

Problems solved by technology

[0004] 1. Soil compaction: Due to the extensive application of chemical fertilizers and neglect of the application of organic fertilizers, soil fertility declines, organic matter is scarce, air permeability is reduced, aerobic microbial activity is reduced, soil maturation is slow, soil compaction is caused, and root growth of vegetables is stunted , affecting crop growth

[0005] 2. Aggravation of salinization: After excessive application of chemical fertilizers, the salt ions in the soil will increase, and the pH value will increase, which will aggravate soil salinization, hinder the normal water absorption of the root system, and affect plant growth

[0006] 3. Lack of trace elements: crops that have been cropped continuously for many years absorb trace elements such as iron, zinc, boron, molybdenum, copper, manganese in the soil, and do not supplement and apply micro-fertilizers in time, resulting in a serious lack of trace elements in the soil and affecting the growth and development of crops

[0007] 4. The active soil layer becomes shallower: the planting of various crops such as vegetables mostly adopts the intercropping production method of stubble and stubble. Most of them are cultivated manually, and large-scale machinery cannot be used for deep plowing, resulting in shallower active soil layers.

[0008] 5. Accumulation of diseases and insect pests: Continuous cropping will increase the accumulation of pathogens and insect pests in the soil, aggravate the damage, cause the root system to suffer and rot, and even the whole plant will die

[0010] Although there are many special fertilizers for economic crops developed for protected areas at present, there are generally problems such as poor effect of improving soil structure and alleviating soil structure deterioration, unbalanced nutrition of fertilizers, single application of chemical fertilizers, and lack of attention to the application of organic matter, etc.
