Example Embodiment

[0016] The present invention will be further described below with reference to the embodiments.

[0017] This example was carried out in Tai'an Township, Yulong County, Lijiang City, Yunnan Province in 2011. The conventional cultivation method was used as a control, and three kinds of treatment methods were adopted to carry out the production demonstration of continuous tablet 100.

[0018] The conventional cultivation method mainly includes the following steps: plowing and raking the soil after harvesting the rapeseed on dry land, artificially digging ditches to level the soil moisture and pounding the ponds, and sowing the rapeseed on demand by planting specifications such as a row spacing of 30-40 cm and a plant spacing of 25-30 cm. Rapeseed seeds are about 0.5 kg, seedlings with 2 to 3 true leaves are seeded 1-2 times, topdressing once, and seedlings are set with 5 to 6 true leaves, cultivating and weeding, and topdressing and cultivating soil. After that, carry out fertil...

Abstract

The invention discloses a method for planting rape in dry land for field management by adopting a small machine. The method comprises the following steps of: after harvesting previous rape in the dry land, carrying out dibble seeding on the rape according to a method of sowing 5-8 grains of seedlings in each row at the row pitch of 50-60cm and the plant space of 15-20cm; finishing final singling in one step when the rape is grown to form 3-5 true leaves; leaving 2-3 seedlings in each row and controlling the density to be 13,000-18,000 plants/mu; when the rape grows to form 6-8 true leaves, scattering 10-15kg of urea as fertilizer for seed bed along a rape row line by one person in front of a walking tractor; and carrying out field management by adopting a method of turning plow, earthing up and covering the fertilizer by using the walking tractor with a plowshare through one person at the back of the walking tractor. According to the method disclosed by the invention, the wide-row and density-planted sowing is carried out to ensure the small agricultural machine can enter the field and participate in management during seedling stage of the rape, the fertilizer for seed bed application, weeding, cultivation and earthing up and ditching one-time operation of the rape in dry land can be realized, the labor input for the field management is reduced, the work efficiency is improved and the timely and effective development of the field management during the seedling stage of the rape is ensured.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for planting rapeseed in dry land suitable for field management by small-scale agricultural machinery. Background technique [0002] rape( Brassica napus ), belonging to Brassicaceae, Brassica, is the main source of vegetable oil for human consumption and one of the main economic source crops for farmers. Rapeseed planting mainly includes paddy field rapeseed with rice as the fore-crop and upland rapeseed with corn and flue-cured tobacco as the fore-crop. Among them, the sown area of ​​dryland rapeseed in Yunnan has reached more than 2 million mu, accounting for more than 50% of the province's rapeseed area, and the per capita arable land in dryland rapeseed production areas is more, and the average dryland rapeseed area per household is more than 5 mu. [0003] Rapeseed is "three-point planting and seven-point management". Timely and effective fie...
