Organic composite fertilizer suitable for potato plants

Abstract

The invention discloses an organic composite fertilizer suitable for potato plants. The organic composite fertilizer comprises the following components in parts by weight: 12-20 parts of potato plant powder, 6-10 parts of fermented seaweed particles, 4-8 parts of banana peel powder, 6-8 parts of potassium nitrate, 6-8 parts of potassium sulphate, 3-5 parts of calcium hydrophosphate, 10-15 parts of urea, 13-15 parts of bentonite, 0.2-0.4 part of sodium borate and 4-8 parts of poultry excrement particles. With plants of potato plants such as sweet potatoes, potatoes, cassava and Chinese yam as main components of the composite fertilizer, absorption of potato plants on nutrients is facilitated; the overall growth of the potato plants is promoted; the organic composite fertilizer is combination of an organic fertilizer and an inorganic fertilizer; the problem that the soil structure is easily damaged by the inorganic fertilizer is solved; the problems that the biological composite fertilizer is short in service life, and the activity is lowered after long-term use are solved; and the yield of the potato plants is improved.

Description

technical field [0001] The invention relates to the field of agricultural production of compound fertilizers, in particular to an organic compound fertilizer suitable for the growth of potato plants. Background technique [0002] Tuber plants mainly refer to a class of terrestrial crops with edible roots or underground stems. There are roots and tubers, such as sweet potatoes, sweet potatoes, cassava, potatoes, yams, and yams. This type of plant is generally weak in cold resistance and is mostly cultivated in the frost-free season. It needs loose, fertile, deep soil and a lot of potassium fertilizer. Multi-line vegetative reproduction, leaving only potato pieces as seeds, and can be propagated with vines, such as sweet potato and cassava. The edible part contains a lot of starch and sugar, which can be used as vegetables, miscellaneous grains, feed, and raw materials for making starch and alcohol. [0003] Potassium is one of the most important elements in the growth of t...

Problems solved by technology

However, because the potassium element in chemical fertilizers is not only unfavorable for the absorption of potato plants, long-term use will also affect the performance of the soil itself, causing problems such as soil compaction and fertility decline; and as an ordinary organic compound fertilizer, the potassium element is relatively less, can not meet the growth needs of potato plants, for the addition of excess potassium, it is necessary to add potassium-containing compounds in organic fertilizers, and more compounds will affect the soil; for most of the microorganisms on the market The bio-fertilizer, due to its own certain storage time, long-term storage will lead to the inactivation of the bio-fertilizer, but because the potato plants themselves need to fertilize irregularly during the growth process, the use effect of the bio-fertilizer is poor
