Embodiment 1

[0023] Apply basal fertilizer when cultivating land. The basal fertilizer applied per mu contains 1500 kg-2000 kg of decomposed chicken manure (containing 22.5% of organic matter, 1.63% of N, 1.54% of P, and 0.85% of K) or other organic fertilizers with equivalent nutrient content. Slow-release fertilizer (containing N 11%, P 2 o 5 14%, K 2 O 17%) 20 kg, ternary compound fertilizer (containing N 15%, P 2 o 5 15%, K 2 O 15%) 20 kg, palygorskite mineral organic fertilizer (containing 30% humic acid) 40 kg, superphosphate (containing 25%-30% CaO) 50 kg, mix well and apply to the cultivated land;

[0024] Apply seed fertilizer when sowing: the seed fertilizer applied per mu contains slow-release fertilizer (including N 11%, P 2 o 5 14%, K 2 O 17%) 10 kg, ternary compound fertilizer (containing N 15%, P 2 o 5 15%, K 2 O 15%) 10 kg, trace element water-soluble fertilizer (containing Mn+Zn+B+Mo ≥ 10%) 1 kg, chitin 0.1 kg, mixed and combined with sowing concentrated appl...

Abstract

The invention relates to the technical field of peanut cultivation, and in particular relates to a special fertilization method for drought and poor land peanuts. The method comprises the following steps: during plowing, applying a base fertilizer, wherein the base fertilizer comprises 1,500-2,000 parts of organic fertilizer, 20 parts of slow release fertilizer, 20 parts of three-nutrient compound fertilizer, 40 parts of palygorskite mineral organic fertilizer and 50 parts of calcium superphosphate; during sowing, applying a seed fertilizer, wherein the seed fertilizer comprises 10 parts of slow release fertilizer, 10 parts of three-nutrient compound fertilizer, 1 part of microelement water-soluble fertilizer and 0.1 part of chitin. According to the fertilization method, the single plant fruiting number is remarkably increased, the single fruit weight is increased, the legume full fruit rate improvement amplitude is large, and the kernel rate can be greatly improved; the seed kernel protein and fat contents of the drought and poor land peanuts can be greatly improved, the content of soluble sugar is reduced, the relative percentage of seed kernel oil acid is greatly improved, the ratio of O / L (oleic acid to linoleic acid) is improved, and the seed kernel quality improvement effect of the drought and poor land peanuts is remarkable.

Description

[0001] technical field [0002] The invention relates to the technical field of peanut cultivation, in particular to a special fertilization method for peanuts in dry and thin land. [0003] Background technique [0004] Due to the poor soil, poor fertilizer supply and water retention capacity of dry ground peanuts, the application of ordinary inorganic fertilizers has a low nutrient utilization rate, which can easily cause defertilization and premature aging in the late growth period and reduce yield. The nutrient release rate, mode and duration of slow-release fertilizers can be well controlled, and are not even affected by complex factors such as soil type. Fat. Applying organic fertilizers to peanuts in dry and thin land can significantly increase soil available P, K nutrient content, organic carbon and total phosphorus content, but the content of alkaline hydrolyzed nitrogen decreases, which affects plant growth, and the effect of increasing yield is not obvious. The ...
