Embodiment 1

[0030] Embodiment 1: the inventive method (abbreviation: base fertilizer+dressing fertilizer+intercropping)

[0031] (1) Intercropping of syringa and stylo: dig a planting pond in the degraded mountainous area of ​​the dry and hot valley of the Jinsha River. The row spacing of the planting pond is 50cm×50cm. In the planting pond, the transplanting method is to plant a row of stylophyllum between two rows of stylophagia; when transplanting, the seedlings of stylophagia and stylophyllum seedlings are both 10-15 cm in height, and the seedlings transplanted in each planting pond There are 1 to 2 seedlings, and 1 seedling after survival.

[0032] (2) Scientific fertilization:

[0033] ① Base fertilizer: Before transplanting the two kinds of seedlings, apply 1200kg / hm combined with site preparation 2 General calcium is the base fertilizer, and P in the general calcium 2 o 5 The content is 16% w / w.

[0034] ② Topdressing: After the two kinds of seedlings survived and new leaves ...

Abstract

The invention discloses a cultivation method for improving the yield and quality of heteropogon contortus. The method includes the steps of heteropogon contortus and stylosanthes guianensis interplanting, scientific fertilization, and field management such as water management and disease and pest control. By adopting the method, the technical problems that heteropogon contortus growing in a dry-hot valley is low in yield and poor in quality and cannot develop into dominant pasture in the region are solved, and meanwhile the problems that when the yield is increased simply by applying nitrogenand phosphorus fertilizer, the effect is unsatisfactory, the fertilizer utilization rate is low, the cost is increased, land is hardened, and groundwater is seriously polluted are solved.

Description

technical field [0001] The invention relates to a cultivation method for improving the yield and quality of thatch, which belongs to the technical field of forage cultivation in dry-hot valleys. Background technique [0002] Heteropogon contortus (Heteropogon contortus) is a perennial gramineous herb growing in hot and dry valleys. It has well-developed fibrous roots, strong tillering ability, and has the advantages of heat-loving, drought-resistant, and poor soil tolerance. Feed for breeding livestock, but at the same time it has the defects of low protein content and low natural growth and yield of grass hills and grass slopes. [0003] Dry-hot valleys are ecologically fragile, soil degraded, and soil nitrogen and phosphorus deficient. In the past agricultural production, the main way to increase crop yield was the application of chemical fertilizers, but its utilization rate has been declining. Too much reliance on chemical fertilizers has caused land compaction, serious...
