Method for improving quality of whole-plant barley for feed of Yellow Sea mud flat reclamation land

Abstract

The invention discloses a method for improving the quality of whole-plant barley for feed in a Yellow Sea mud flat reclamation land. The method comprises the following steps: (1) variety screening and seed quality improvement; (2) treating the seeds, tedding the seeds for 2-3 days before sowing, and dressing the seeds with a coating agent; (3) depth-limited soil preparation: salinization and depletion of the Yellow Sea mud flat reclamation land; (4) anti-stain and salt-and-alkali-resistant ditch construction; (5) sowing, and controlling the sowing time before November 10, (6) improving the quality of nitrogen fertilizer, applying the nitrogen fertilizer at the tillering stage, and promoting tillering increase, wherein the pure N is equal to 4kg / mu; in the 2-3-leaf stage of wheat seedlings, nitrogen fertilizer is applied, and pure N is 7 kg / mu; nitrogen fertilizer is used in the jointing stage, and pure N is 8 kg / mu; (7) strengthening stems and resisting lodging, and dressing K2O according to the ratio of 4kg / mu in the jointing stage; (8) performing daily management, performing ditch cleaning and ridging in the whole growth period, ensuring that a ditch system is sound and smooth, strictly preventing waterlogging damage, and paying attention to prevention and control of diseases and insect pests; (9) harvesting at a proper period, namely harvesting barley for coastal saline-alkali land feed, controlling harvesting before May 5th when seeds reach a milk-ripe period and yellow leaves of stalks are lower than 10%, and avoiding coastal strong wind and dry weather so as to facilitate development of conditioning work.

Description

technical field [0001] The invention relates to a method for improving the quality of whole-plant barley used for feed in reclamation land reclamation of Huanghai beach. Background technique [0002] Barley is a high-quality feed for livestock and poultry, which can not only replace energy feed but also make up for the shortage of some protein feed resources. Both barley grain and straw can be used as feed and directly used in animal husbandry production. In the context of the rapid development of animal husbandry in my country, the transformation of barley production into feed can effectively make up for the gap in corn supply, reduce breeding costs, and ease the pressure of "human and animal competition for food". At the same time, the planting cycle of barley for feed is short, usually in April-May Harvested and used as silage and silage, it is beneficial to the preparation of early stubble and stubble in the farmland. [0003] The barley grown along the Yellow Sea in Ji...

AI Technical Summary

Problems solved by technology

[0003] The barley grown along the Yellow Sea in Jiangsu is mainly used for beer production, and its products and feed uses have obvious shortcomings: first, the planting density is low, only about 50% of the feed is used, which seriously limits the overall production level; second, the height of barley plants is too high The overall biomass level is not high; the third is that the crude protein content of the whole barley is as low as about 8%, which cannot meet the needs of animals; the fourth is that only late-maturing seeds are harvested, which is not conducive to further preparation and animal intestinal absorption
