Problems solved by technology

[0003] At present, farmyard manure and quick-acting fertilizers are widely used in the traditional planting of sage bean. The fertilizer is easy to lose, and the fertilizer effect period is short. Repeated fertilization will easily cause the green seedlings of sage bean to grow excessively, which will affect the yield.
In view of the unique soil characteristics of saline-alkali land, the application of ordinary fertilizers cannot alleviate the stress effect of saline-alkali on C. oleifera, resulting in the final yield not reaching a high level. In addition, there are few slow-release components in traditional fertilizers, and the timing of fertilization needs to be strictly controlled. It requires repeated fertilization, resulting in the consumption of manpower, which is not conducive to the development of ecology, but also increases the cost of planting, resulting in a low level of economic value of planting oily bean

Abstract

The invention relates to compound fertilizer special for cyperus esculentus planted in saline-alkali soil and belongs to the technical field of fertilizer preparation. The fertilizer specifically comprises 10-15 parts of controlled-release resin coating urea, 4-10 parts of calcium superphosphate, 5-10 parts of potassium sulfate, 40-60 parts of livestock and poultry manure, 50-60 parts of ardealitemodifier, 15-20 parts of diammonium phosphate, 5-8 parts of sulfur powder, 5 parts of sodium ion adsorbent and 0.5 part of Arabic gum powder. The compound fertilizer has the advantages that the compound fertilizer can relieve the influence of salt and alkali on cyperus esculentus growth, the salt and alkali content of the saline-alkali soil can be lowered, the cyperus esculentus planted in saline-alkali soil is promoted to achieve high quality and high yield, ecological, healthy and sustainable development of saline-alkali soil agriculture of China is guaranteed, reasonable material proportioning is performed according to absorption law of nutrition required during cyperus esculentus planting, quick-action and controlled-release materials are combined, sufficient fertilizer utilization isachieved, and fertilizer loss is reduced.

Description

technical field [0001] The invention relates to a compound fertilizer specially used for planting saline-alkali land of oily sedge and a preparation method thereof, and belongs to the technical field of biological fertilizer manufacturing. Background technique [0002] With the continuous expansion of saline-alkali land area in my country, planting high-efficiency salt-tolerant economic crops through screening is one of the best ways to improve and utilize saline-alkali land resources. The content of saline-alkali components in saline-alkali soil is high, and saline-alkali stress has a significant inhibitory effect on the growth and physiological characteristics of general crops. There are few economic crops suitable for planting in saline-alkali soil. Youshadou has the characteristics of drought tolerance, barren tolerance, saline-alkali tolerance, strong stress resistance, good adaptability, excellent oil quality, and high starch content. It is a good choice for improving ...
