Embodiment 1

[0015] A no-tillage direct seeding cultivation method for rapeseed in a double-cropping rice area, comprising the following steps:

[0016] (1) Drain and dry the field in time before the late rice of the previous crop is harvested. After the harvest, the ditch is opened to prepare the land. Potassium 8kg and borax 1kg are used as base fertilizer, sow in no-tillage drill method, 350g per mu;

[0017] Seed treatment: dry the seeds for 3-4 hours before sowing, then soak the seeds in warm water at 50°C for 2-3 hours, and sow directly after drying;

[0018] (2) Apply 8 kg of urea and 5 kg of potassium chloride per mu at the seedling stage, apply 5 kg of urea and 3 kg of potassium chloride per mu when the rape is budding and bolting, and use 0.2% borax solution or dihydrogen phosphate at the seedling stage and full flowering and pod stage respectively Potassium is sprayed on the leaves to increase the seed setting rate; regular cultivating and weeding; 4 leaves of rapeseed, spray 5...

Embodiment 2

[0022] A no-tillage direct seeding cultivation method for rapeseed in a double-cropping rice area, comprising the following steps:

[0023] (1) Drain and dry the field in time before the harvest of the late rice of the previous crop. After the harvest, ditch the land and prepare the land. Potassium 6kg and borax 1kg are used as the base fertilizer, and no-tillage drill method is used for sowing, 420g per mu;

[0024] Seed treatment: dry the seeds for 3-4 hours before sowing, then soak the seeds in warm water at 50°C for 2-3 hours, and sow directly after drying;

[0025] (2) Apply 10 kg of urea and 5 kg of potassium chloride per mu at the seedling stage, apply 7 kg of urea and 3 kg of potassium chloride per mu when the rape is budding and bolting, and use 0.2% borax solution or dihydrogen phosphate at the seedling stage and full flowering and pod stage respectively Potassium is sprayed on the leaves to increase the seed setting rate; regular cultivating and weeding; 4 leaves o...

Abstract

The invention discloses a double-cropping-rice-area oilseed-rape no-tillage and direct seeding cultivation method. The double-cropping-rice-area oilseed-rape no-tillage and direct seeding cultivation method includes the following steps that water draining and field drying are carried out in time before preceding-crop late rice is harvested, ditching and land preparation are carried out after the preceding-crop late rice is harvested, the ridge width is 133 cm to 150 cm, the furrow width is 30 cm, and the furrow depth is 15 cm; base fertilizer is fully applied, seeding is carried out in a no-tillage and drilling mode, and the amount of seeds which are seeded per mu is 350 g to 420 g; fertilizing is carried out during seedling stage and oilseed-rape budding and bolting, leaf surface spraying is carried out with borax liquid of 0.2% or monopotassium phosphate in the seedling stage and full-bloom and pod bearing stage respectively, and the setting percentage is increased; intertilling and weeding are carried out at fixed period; diseases and pests are controlled; at the time 30 days to 35 days before the oilseed-rape full-bloom stage end, seeds in pods become yellow from green, and when the color is red, harvesting can be carried out. According to the double-cropping-rice-area oilseed-rape no-tillage and direct seeding cultivation method, labor and time are saved, cost is saved, the contradiction of crops for rotation in the double-cropping-rice area can be released, the cropping system is improved, the land utilization rate is increased, and economic benefits are improved.

Description

technical field [0001] The invention belongs to the field of crop cultivation, and in particular relates to a no-tillage direct seeding cultivation method for rapeseed in a double-cropping rice area. Background technique [0002] Rapeseed has a long history of cultivation, and China and India are the oldest countries in the world to cultivate rapeseed. India is the most planted rapeseed in the world, followed by China, and Canada ranks third. A large part of rapeseed is used to make edible rapeseed oil, which contains a variety of vitamins, such as vitamin A, vitamin D and vitamin E, and is an important source of fat-soluble vitamins for the human body. Vegetable oil is rich in vitamin E, up to 60 mg / 100 g of oil, especially the content of type A vitamin E is as high as 13.2 mg / 100 g of oil, which is 2.58 times that of soybean oil, and it will not decrease much after long-term storage and heating. Sources of vitamin E in foods. The content of phytosterols in rapeseed oil ...
