Application of Organic Fertilizers Optimizes Water Consumption Characteristics and Improves Seed Yield of Oilseed Flax in Semi-Arid Areas of the Loess Plateau

Organic fertilizers are an important source of nutrients for improving farmland fertility. To explore high-yield, efficient and green production technology oilseed flax in dryland agricultural areas, a field split plot experiment was conducted the semi-arid area Loess Plateau northwest China from April to August 2020 2021. The study compared analyzed effects different nutrient sources their application rates on water consumption characteristics, grain yield use efficiency flax. main plots were fertilizer types (sheep manure, chicken manure chemical fertilizer), while subplots manure: S1-12,500 kg·hm−2 S2-25,000 kg·hm−2; C1-5800 C2-11,600 fertilizer: F1-N 112.5 kg·hm−2, P 75 K 67.5 F2-N 225 P2O5 150 K2O 135 kg·hm−2). results showed that with fertilizers, organic significantly increased soil storage capacity 0–160 cm layer during whole growth period reduced consumption. During two growing seasons, 25,000 sheep seedling-bud fruit period-maturity by 16.13% 23.19% CK, respectively. Thousand-grain weight, 14.70%, 48.32% 61.29%, These indicate can increase layer, reduce thus improve It is suitable fertilization areas Plateau.
