Embodiment Construction

[0019] After the autumn harvest on October 20, 2003, the present invention adopts a 20-horsepower agricultural tractor to hang a stubble cutter to implement stubble removal, and then hangs a three-share plow to break the ridge-opening platform to make ridges. From May 1st to 2nd, 2004, a 20-horsepower agricultural tractor was used to hang a ditch opener on the front beam, a fixed fertilizer applicator on the left wing, a fixed planter on the right wing, a drought-resistance tank loaded with 1.5 tons of water in the trailer, and a "V" behind the trailer Type soil cover. Drive the tractor on the ridge platform, adjust the height of the ditch opener, open 8-10cm shallow ditch in the ditch, adjust the fertilizer applicator, so that the diammonium phosphate is evenly spread in the shallow ditch, and control the flow rate of the fertilization amount to make the fertilization amount reach 230 -250 kg / ha; adjust the water valve of the anti-drought cylinder, sit in the shallow ditch, a...

Abstract

A method for cultivating corn in order to fight against drought and preserving the fertilizer in soil includes such steps as preparing soil in the autumn for collecting the rain in the soil, sowing in the spring in the furrow mode for decreasing the loss of water and soil, topdressing, and changing the furrows to bed for preserving water and fertilizer.

Description

technical field [0001] The invention belongs to farmland farming management, is especially suitable for dry farming and rain-fed agriculture in semi-humid and semi-arid regions in Northeast China, and is a novel corn farming method for drought resistance, seedling preservation, fertilizer preservation, wind erosion prevention, weed control and high yield. technical background [0002] Northeast temperate zone semi-humid, semi-arid climate type, annual precipitation 300-500mm, with an average of 419.8mm, 60-70% concentrated in June-August. The annual evaporation is 1600mm, which is about 3.5 times of the precipitation. The spring is dry and rainless, and the weather is very windy. The annual average wind speed is 4.8m / s. The maximum average wind speed occurs in April and the minimum wind speed occurs in August. The zonal soil types are chernozem and chestnut soil, and the non-zonal soils are aeolian sandy soil and saline soil. [0003] Most grasslands in this area are recla...
