Jatropha curcas dedicated composite fertilizer, preparation method and applications thereof

Abstract

The invention discloses a jatropha curcas dedicated composite fertilizer, a preparation method and applications thereof. The dedicated composite fertilizer is prepared from the following components in parts by weight: 30 to 35 parts of banana stalk, 35 to 40 parts of manure of livestock and poultry, 5 to 12 parts of liquid monosodium glutamate dreg, 10 to 13 parts of peanut bran powder, 1 to 3 parts of jatropha bran powder, 0.02 to 2 parts of plant insecticide, 1 to 2 parts of water-retaining agent, 0.002 to 0.010 part of microbial inoculant, 1 to 2 parts of urea with a nitrogen content not less than 46.4%, 3 to 4 parts of calcium superphosphate with a P2O5 content not less than 12%, and 2 to 3 parts of potassium chloride with a K2O content not less than 60%. The provided fertilizer is suitable for being used in the seedling period and topdressing period and can be used as a base fertilizer. The jatropha curcas dedicated composite fertilizer has comprehensive and abundant nutrients, can provide enough nutrients for jatropha curcas, and is capable of preventing diseases and insects. Jatropha curcas is usually planted in water-deficient areas such as hillside, high mountains, and the like, and the provided fertilizer can relieve water deficiency. Moreover, the raw material source is wide, the cost is low, and the preparation technology is simple. So the fertilizer can promote the sustainable development of rock desertification region and generates good economic benefit, social benefit, and ecological benefit.

Description

technical field [0001] The invention belongs to the field of special fertilizers for plant growth, and relates to a special compound fertilizer for jatropha curcas, a preparation method and an application thereof. Background technique [0002] Jatropha ( Jatropha curcas L. ) is a plant of the genus Jatropha (Euphorbia L.), a deciduous shrub or small tree, and a perennial woody oil plant.
