Water retention and sustained-release combined cup fertilizer

Abstract

The invention discloses a water retention and sustained-release combined cup fertilizer, which comprises a water retention fertilizer and a sustained-release fertilizer, wherein the water retention fertilizer is prepared by mixing a dried base stock formed by plant fibers and a quick-acting water-soluble fertilizer, konjaku flour and a bonding agent; the water retention fertilizer and the sustained-release fertilizer which are in a solid columnar shape are put in a fertilizer cup, the water retention fertilizer is positioned on the upper part of the fertilizer cup, and the sustained-release fertilizer is positioned on the lower part of the fertilizer cup; and a cavity is formed in the center of the water retention fertilizer. By the combined cup fertilizer, moisture and fertilizer nutriments which are required by seedlings during the initial period of field planting and the fertilizer nutriments required by plants during the growth period in the future are combined together, the moisture and fertilizer nutriments which are required by the plants can be provided only by watering and fertilizing once, and thus, the invention has the advantages that the combined cup fertilizer has good effects of water absorption and storage and high the drought resisting performance, is environment-friendly and does not pollute water sources and soil; and due to the utilization of rejected materials serving as raw materials, the combined cup fertilizer has low cost and is economical and practical, is time-saving and labor-saving in production and application, can be produced by standard assembly production lines, is easy to operate and control and the like, and has the excellent social and economic benefits.

Description

technical field

[0001] The invention belongs to the technical field of agricultural science and technology, and specifically relates to an organic-inorganic compound compound cup fertilizer which mainly uses waste plant source materials to produce a new type of water-retaining fertilizer and is used in combination with a slow-release fertilizer. Background technique

[0002] In the planting and growth process of plants, the satisfaction of water and fertilizer are two extremely important aspects. Soil fertility, commonly known as soil fertility, is the embodiment of the comprehensive nourishment effect of soil moisture, air, heat and fertilizer on the root system of crops during the growth process. Crop seedlings are taken out from the nursery bed and planted in the field. First, it needs to absorb enough water from the soil for a certain period of time to rejuvenate the roots and realize greening; secondly, it needs to absorb more water-soluble phosphorus (P 2 o 5 ) and n...
