Abstract

The invention discloses a cultivation method achieving high yield of multiple cropping silage maize and efficient utilization of water and nitrogen. The cultivation method is characterized by comprising following steps: selecting varieties and drying seeds in the sun; selecting farmland and performing sowing; performing field management at the seedling stage, jointing stage, teaseling and boll opening stage and filling stage. The cultivation method has following beneficial effects: strong operability and high yield of silage maize. By use of the cultivation method, the utilization rate of water and nitrogen is increased; environmental pollution caused by excessive irrigation and fertilization is reduced; economic benefit and social benefit are remarkable; the purposes of high yield, water conservation, fertilizer conservation, and efficient utilization of water and nitrogen of multiple cropping silage maize under drip irrigation are achieved. The cultivation method plays a great role in breaking through the limitation of water resources on bi-annual planting under drip irrigation in northern Xinjiang.

Description

technical field [0001] The invention relates to a planting method for high-yield, water-nitrogen and high-efficiency utilization of multi-sowing silage corn, and belongs to the technical field of corn planting. Background technique [0002] Green storage corn refers to harvesting fresh and tender corn plants, or harvesting whole corn from the early stage of milk ripening to wax ripening stage, or picking the ear at the wax ripening stage, and then cutting off the plants with green stems and leaves, chopped and processed directly Or stored and fermented for livestock feed. For ruminants such as cattle and sheep, the highest value-added way of corn feed conversion is the whole plant green feed. Corn silage feed has been valued by many animal husbandry developed countries because of its high nutritional value and economic benefits. Under normal conditions, the moisture content of corn silage feed is about 75%. If calculated according to the air-dried state, it is roughly 4kg ...
