Culture method for red date tree and alfalfa intercropping

Abstract

The invention discloses a culture method for red date tree and alfalfa intercropping, and belongs to the technical field of crop culture. The method includes the steps of stabilizing spring temperature to be 5 DEG C and above, planting red date tree seedlings with height larger than or equal to 80 cm, thick root thickness larger than or equal to 0.3 cm and side root thickness larger than or equal to 20 cm according to the line spacing of 5.0-6.0 m and the row spacing of 2.0-3.0 m; conducting broadcasting sowing or strip sowing on alfalfa outside the perpendicular projection of date tree crowns according to the line spacing of 25-35 cm and the sowing depth of 1.0-1.5 cm, wherein when the seedling emergence density is 135-270 plants per square meter, the sowing amount is advisable; harvesting one crop of alfalfa in the current year, starting to harvest 3-4 crops of alfalfa every year from the second year, and harvesting alfalfa for the last time not later than the end of September, wherein the height of stubbles reserved in each time of harvesting is not lower than 5.0 cm, and the height of stubbles reserved in the last harvesting is not lower than 10.0 cm. Organic planting of red dates is achieved through alfalfa intercropping, natural resources can be sufficiently used, the aims of effectively increasing planting density and increasing soil and solar energy utilization rate are achieved, the technical support is provided for red date dwarf and close planting type efficient economic forest planting, and the method has ecological benefit, social benefit and economic benefit.

Description

technical field [0001] The invention relates to a method for cultivating jujube intercropping alfalfa and belongs to the technical field of crop cultivation. Background technique [0002] The jujube tree is a small tree that grows in the temperate zone. It is native to China and is planted in most parts of our country. province and Xinjiang emerging jujube producing areas. The flowers are small and honey-rich, which is a kind of nectar source plant; the flower color is light yellow and has an aromatic smell. The fruit is jujube, oval, yellow when immature, and brownish red when ripe. It can be eaten fresh or made into dried fruit or candied fruit. Nutritious, rich in iron and vitamins. But none of the planting methods is intercropping jujube and alfalfa. By planting jujube trees intercropping alfalfa, jujube and livestock can be raised together, and the comprehensive development and utilization of jujube products and livestock products can simultaneously promote the sust...

But none of the planting methods is intercropping jujube and alfalfa. By planting jujube trees intercropping alfalfa, jujube and livestock can be raised together, and the comprehensive development and utilization of jujube products and livestock products can simultaneously promote the sustainable development of agricultural production, industrial processing and commercial markets. development, and play an important role in ecological, low-carbon, and circular green agriculture in beautifying mountains and rivers, improving the ecological environment, restoring ecological vegetation, and returning farmland to forests and grasses by planting jujube intercropping alfalfa, which will play an important role in the future animal husbandry In terms of industrial development, it is of great significance
