Compound fertilizer for domestic indoor aquatic potatoes

Abstract

A compound fertilizer for indoor aquatic potatoes in a family, comprising 3-5 parts of peat, 2 parts of perlite, 1 part of river sand and an appropriate amount of fertilizer calculated by volume. Among them, the peat is coarse peat, with a particle size of 10-30mm; the river sand is the fine sand for the construction site screened by the sieve size (2-4mm); add 20kg of organic fertilizer, 10kg of vegetable cake fertilizer, and 0.5kg per cubic meter before the fertilizer is loaded into the pot. Compound fertilizer (15:15:15). The physical and chemical indicators of compound fertilizer are: PH value: 5.5-6.5, electrical conductivity 0.5-2ms / cm, bulk density 0.3-0.5g / cm3, total porosity 55-60, ventilation pores 20-22%, water-holding pores 35-40 %, air-water ratio 1:1.5-2.0. Potted potatoes are used to eliminate soil-borne diseases, improve the quality and yield of potato fruits by about 20%, have high practical value, have many root systems, and have luxuriant plant growth, which meets the aesthetic effect of bonsai.

Description

【Technical field】 [0001] The invention relates to a cultivation fertilizer, in particular to a compound fertilizer used for domestic indoor aquatic potatoes. 【Background technique】 [0002] Soilless fertilizer cultivation has the following advantages: (1) It is not limited by soil conditions and can be cultivated in places and environments that are not suitable for soil cultivation. It can be carried out in areas with poor soil, arid areas, and saline-alkali land, making full use of land resources. (2) Solid fertilizers have strong permeability to water and air, which makes it easier to adjust the water and air in the root environment and is more conducive to the development of the root system. (3) Irrigation and fertilization are relatively accurate, and can accurately supply the water and nutrients needed by crops according to the needs of water and nutrients in different growth stages of crops. It is easy to obtain high yield, and the product quality is improved. (4) C...

Problems solved by technology

But for potato cultivation, its high water holding capacity is a disadvantage

Potatoes are afraid of waterlogging, the large water holding capacity of peat is not good for the growth of potato roots, it is prone to hypoxia, and the survival rate is relatively low

[0004] At present, peat is the most widely used cultivation fertilizer in production, but the price of peat is high, and resources are limited, so it is not suitable to use in large quantities.
