Organic compound fertilizer suitable for growth of asparagus lettuce

Abstract

The invention discloses organic compound fertilizer suitable for growth of asparagus lettuce. The organic compound fertilizer comprises the following components in parts by weight: 15-20 parts of straw mushroom dregs, 7-10 parts of pine forest surface soil particles, 5-8 parts of maize straw particles, 3-4 parts of silkworm excrement particles, 0.1-0.2 part of potassium sulfate, 0.2-0.3 part of potassium dihydrogen phosphate, 1.0-1.15 parts of urea, 0.01-0.02 part of sodium borate, 3-5 parts of plant ash and 60-80 parts of distilled water. The organic compound fertilizer disclosed by the invention is the solid-liquid combined type fertilizer; the fermented organic compound fertilizer provides necessary nitrogen fertilizer and potash fertilizer for asparagus lettuce in the growth process of the asparagus lettuce; solid components in the organic compound fertilizer are enriched on the soil surfaces of plant root systems, after being dispersed and diluted by liquid components, the solid components are drained to the plant root systems, and simultaneously, the liquid components contain lots of absorbable nutrient substances; and the whole fertilization process is simple and convenient, and all resources are comprehensively used.

Description

technical field [0001] The invention relates to the production field of organic compound fertilizers for crops, in particular to an organic compound fertilizer suitable for lettuce growth. Background technique [0002] Lettuce is a variety of Lactuca genus Lactuca in the Asteraceae family that can form fleshy tender stems. The stems above the ground are edible, the skin of the stem is white and green, the flesh is crisp and tender, the young stems are emerald green, and turn white-green when mature; rich in nutrients and high edible value; lettuce has strong adaptability and can be cultivated in spring and autumn or overwintering , mainly cultivated in spring and harvested in summer. [0003] During the growth process of lettuce, fertilization is required at multiple stages; for fertilization during the growth process, solid organic compound fertilizers cannot be directly spread into the soil, and the solid fertilizer on the soil surface is not conducive to the absorption o...

Problems solved by technology

[0003] During the growth process of lettuce, fertilization is required at multiple stages; for fertilization during the growth process, solid organic compound fertilizers cannot be directly spread into the soil, and the solid fertilizer on the soil surface is not conducive to the absorption of lettuce plant roots, which in turn leads to lettuce plant growth. However, in comparison, most of the liquid organic compound fertilizer is water, and its nutrient content is low. In order to meet the needs of a single plant, a large amount of liquid organic compound fertilizer is sprayed during the operation; fertilization Time-consuming and low work efficiency
