Embodiment

[0019] Embodiment: Ferment after mixing crop stalks and livestock and poultry manure with 30:65 (by dry weight), when the composting temperature rises to 60-70°C, keep it for 5-7 days (turning the compost once a day), and then wait until the composting temperature rises to 60-70°C. When it reaches about 60°C, keep it for 5-7 days (turn the compost once every 2-3 days), until the compost temperature starts to drop from 50-60°C, and then compost for 8-10 days for further post-ripening, and the fermented organic materials are combined with 2 % (dry weight percentage) ammonium chloride mixed, granulated to make total nitrogen content is more than 4% (more than 10% of nitrogen, phosphorus and potassium total nutrients), organic-inorganic compound fertilizer (table 1) more than 30% of organic matter.

Abstract

A fertilizer for continuous cropping of agricultural crops, especially the watermelon, cucumber, and tomato, is prepared from the straw and stalk of agricultural crops, dung of animal and droppings of fowls through proportional mixing and fermenting.

Description

1. Technical field [0001] The invention relates to a fertilizer capable of eliminating obstacles to crop continuous cropping and a production method thereof, which belongs to the agricultural intensive production technology and is specially used for overcoming and eliminating crop continuous cropping obstacles. 2. Technical background [0002] The continuous cropping obstacles of melons, fruits and vegetables are the bottleneck of global intensive agricultural production. Thousands of hectares of protected agricultural soil are constantly being abandoned due to continuous cropping obstacles, which greatly wastes the financial, human and material resources invested in facility agriculture. Therefore, there are so many studies and reports on the problem of continuous cropping obstacles of vegetable crops, but there are not many that really solve practical problems, or it can only be said that the problem of continuous cropping obstacles has been alleviated to a certain extent, ...
