Water-saving, fertilizer-saving, drought resisting and nourishing composite material

Abstract

The water-saving, fertilizer-saving, drought resisting nourishing composite material includes water isolating layer, composite nourishing layer inside the water isolating layer and with N, P, K, Zn, Mo, Ca, B and other elements, water permeating layer of filtering paper, water absorbing resin set beteen composite nourishing layer and the water permeating layer, plant growth regulator and refined nitrogen fertilizer stored in the filtering paper or water absorbing resin. The said structure possesses the comprehensive functions of fast water absorption, water accumulation, delayed water and fertilizer supply, promoting crop's health growth, etc. It is suitable for for the plantation of various crops and trees in drought and semi-drought area, and plantation in greehouse.

Description

Technical field: [0001] The invention belongs to materials used in agriculture, forestry and planting, in particular to a water-saving and fertilizer-saving material for promoting the healthy growth of plants, which is suitable for crop transplanting and seedling raising. Background technique: [0002] In order to improve the ecological environment in arid and water-deficient areas, afforestation must be planted. However, how to improve the survival rate of tree planting in arid and less rainy areas? [0003] The arable land in our country is limited, how to use the least amount of water and fertilizer to produce more cash crops such as food, vegetables, flowers and so on to meet people's ever-increasing demands; [0004] As a result of long-term continuous cropping of the soil, soil-borne diseases and insect pests are becoming more and more serious, and soil accumulation reduces crop yield and quality. Greenhouse planting is even more serious. How can we ensure that each st...

Problems solved by technology

Since the inner bag and the outer bag of this water-saving seedling nutrition water-retaining paper bag are made of ordinary paper, the outer bag cannot be separated from water for a long time, and the inner bag cannot be quickly permeable. On the one hand, the resin cannot quickly absorb enough water, and it is prone to false saturation of the water-absorbing resin. On the other hand, the dry soil outside the bag will inevitably absorb the water and nutrients in the bag through the outer bag, because the water in the soil outside the bag volatilizes very quickly. Quickly, the roots of the transplanted crops planted in the soil in the bag have not absorbed enough water and nutrients, and the water and fertilizer in the bag have been volatilized a lot, which will inevitably affect the survival and growth of the crops.

Simultaneously this water-saving type nursery stock nutrition water-retaining paper bag can only be applicable to the planting and transplantation of plant-like plants, then can't use for loose plant such as lawn, seedling, wheat, vegetables etc., although this water-saving type seedling nutrition water-retaining paper bag is suitable for Transplanting plants can have a certain effect, but its use effect and scope of use are limited
