Degradation type environment-friendly controlled-release fertilizer in turnip planting

Abstract

The invention discloses a degradation type environment-friendly controlled-release fertilizer in turnip planting. The controlled-release fertilizer comprises the following components in parts by weight: 30-40 parts of fermentation residue, 7 parts of urea ammonium polyphosphate, 3-5 parts of calcium ammonium nitrate, 3-5 parts of calcium hydrogen phosphate, 4-6 parts of potassium chloride, 3-4 parts of animal and vegetable oil, 2-3 parts of C12-C20 alkane sulfonate, 10-12 parts of proline, 5-6 parts of hydroxyproline, 2-3 parts of an extension agent, 2-3 parts of a microelement mixed mini-fertilizer, 10-20 parts of algae and 10-15 parts of humus. According to the fertilizer disclosed by the invention, the release speed of the degradation type controlled-release fertilizer is changed; the anti-caking property is good; the loose degree reaches 98%; the plant growth can be promoted; the growth of various pathogenic bacteria in the soil is inhibited; the growth of various types of threadworms or soft insects in the soil is inhibited; the trace elements mixed micro-fertilizer is balanced and comprehensive in nutrient; the crop yield can be obviously improved; the crop quality is improved; the fertilizer is rapid in absorption, high in effect, strong in function, high in disease elimination efficiency; the nutrient utilization rate is high; and the fertilizer has wide application prospect.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to a degradable environment-friendly controlled-release fertilizer for planting kohlrabi. Background technique [0002] The field for planting kohlrabi should have a deep soil layer, convenient drainage and irrigation, fertile soil, and sandy loam is better. Kohlrabi can be broadcast live or seedlings, generally seedlings. The sowing period is from late August to mid-September. Variety can choose Wenling kohlrabi, the amount of seed used is 150 grams per mu for direct seeding, and 25 to 50 grams for seedling cultivation. When raising seedlings, first prepare the seedbed carefully, and sow 250-400 grams per acre of seedbed, which can be used for 10-15 mu of field planting. Cover with straw or sunshade net after sowing, and remove after emergence. Thin the seedlings once about 10 days after emergence, with a seedling distance of 6-8 cm, and topdress with dilute manur...

Problems solved by technology

Chemical fertilizers are easy to absorb moisture in the air, and are easy to agglomerate during production and storage. The appearance and quality of chemical fertilizers are affected to a certain extent after agglomeration, and at the same time bring a lot of inconvenience to handling and use. It is necessary to smash the agglomerated fertilizer with hard things to facilitate the absorption of nutrients in the fertilizer. It is very inconvenient to use such fertilizer, and it takes time to break the agglomerated fertilizer, which is time-consuming and labor-intensive. And it is difficult to achieve the effect before no agglomeration

In addition, plants often suffer from diseases, such as viruses, bacteria, molds, fungi, insects, etc. Even if the plants suffering from diseases are sprayed with foliar fertilizers, it is difficult to absorb them, and eventually the plants will die
