Nutritional organic medium for planting of carya illinoensis

Abstract

The invention discloses a nutritional organic medium for planting of carya illinoensis. The nutritional organic medium is prepared from the following raw materials in parts by weight: 20-24 parts of defatted soybean meal, 35-38 parts of soy sauce residue, 28-32 parts of common duckweed, 3-4 parts of potassium feldspar powder, 1-2 parts of propylene glycol alginate, 2-4 parts of calcium lactate, 42-46 parts of turf, 2-3 parts of gamma-polyglutamic acid, 40-42 parts of wheat straw, 2-4 parts of urea, 20-24 parts of peat soil and a proper amount of water. The proportioning of the nutritional organic medium disclosed by the invention is balanced according to the specific nutrient requirements of the carya illinoensis; the purpose of achieving the high nutrient utilization ratio, the high production controllability and the like is fulfilled; and meanwhile, the problems about the strict production site requirements, the complex control of diseases and insect pests, and the like in the traditional planting of the carya illinoensis are solved, thereby achieving the high quality and high yield of the carya illinoensis.

Description

technical field [0001] The invention relates to the technical field of nutrient substrates, in particular to a nutrient organic substrate for planting pecans with thin shells. Background technique [0002] Substrate cultivation is an important cultivation method, which is a soilless cultivation method that absorbs nutrients through the substrate. Due to its low requirements on the soil environment, simple equipment, water and fertilizer saving, etc., it is adopted by the majority of planting producers. application. With the continuous development of my country's planting industry and the continuous expansion of the planting area, the use of cultivation substrates is also increasing. The traditional substrates prepared from single raw materials such as peat and vermiculite or simply mixed can no longer meet the needs of planting. At this stage, the substrate generally has a single nutrient. At the same time, the physical properties of the substrate during use are unstable, po...

Problems solved by technology

With the continuous development of my country's planting industry and the continuous expansion of the planting area, the use of cultivation substrates is also increasing. The traditional substrates prepared from single raw materials such as peat and vermiculite or simply mixed can no longer meet the needs of planting. In this stage, the substrate generally has a single nutrient. At the same time, the physical properties of the substrate during use are unstable, poor water absorption, easy to collapse, and low added value. It is impossible to achieve high application value for specific cultivation objects and environments, which affects the growth of economic benefits.
