Embodiment 1

[0017] In 2018, 20 mu of permeable mulch film was set up on the flat land of Xiejiagou Village, Jia County, Shaanxi Province to cover the experiment of double-row corn (Dafeng 30 variety) with micro-furrows on the back of the ridge.

[0018] According to the method of the present invention, the test selects the fully biodegradable water-permeable mulch film with a width of 600 mm×thickness 0.007 mm, and adopts the 2MB-1 / 2 type film-laying drill machine produced by Changzhi Shenhe Yongcheng Agricultural Machinery Technology Development Co., Ltd. The machine is refitted, and a ditching disc (6) with a diameter of 230 mm is installed on the front beam (7) of the frame of the film seeding machine corresponding to the central position of the micro-groove (11) on the back of the ridge. (5) The place 160mm away from the rear end is the place where the steel shaft is connected (8), and the matching steel roller is connected to the plastic shaping module, and a steel roller (1) is arran...

Embodiment 2

[0021] In 2018, 30 mu of sorghum (Jinza No. 12) permeable plastic film was laid on the flat land of Yuancha Village, Jinmingsi Town, Jia County, Shaanxi Province, and the sowing test was covered with one film and three rows of micro-grooves on the back of the ridge.

[0022] According to the method of the present invention, the 2MB-1 / 3 type film laying hole seeder produced by Changzhi Shenhe Yongcheng Agricultural Machinery Technology Development Co., Ltd. is selected to use a fully biodegradable water seepage film with a width of 1300 mm×a thickness of 0.007 mm, and refit the film laying hole seeder , install a ditching disc (6) with a diameter of 230mm at about 250mm on both sides of the center of the front beam (7) of the frame and at the corresponding positions of the two ridge back micro-grooves (11); (5) The place 150mm away from the rear end is the place where the steel shaft is articulated (8), and the matching steel roller is articulated to suppress the plastic module,...

Embodiment 3

[0025] In 2017, 25 mu of permeable plastic film covering micro-grooves on the back of the ridge was carried out on the dry plains of Yangta Village, Fangta Town, Jiaxian County, Shaanxi Province, and a millet sowing test was carried out in one film and four rows. The variety was Jingu 21.

[0026] According to the method of the present invention, select width 1650 mm * thickness 0.007mm fully biodegradable water seepage mulch film, Changzhi City Shenhe Yongcheng Agricultural Machinery Technology Development Co., Ltd. produces 2MB-1 / 4 type film laying hole seeder, through refitting, in front of the frame A ditching disc (6) with a diameter of 230mm is installed at the corresponding positions of the crossbeam (7) and the micro-groove (11) on the back of the ridge, and the frame is articulated at a distance of 150mm from the rear end of the longitudinal beam (5) on both sides of the frame. The shaft (8) is connected with the matching steel roller pressing and shaping module, and a...

Abstract

The invention discloses a biodegradable water-permeable mulching film ridge back microgroove multi-row mechanical film-mulching and sowing method and aims to solve the problem of efficient utilizationof drizzle resource and nutrient by dry land in semiarid areas and the problem that full-biodegradable mulching films are too fast in breaking and disintegrating in the crop seedling period. The method includes: making a steel roller compacting and shaping module which is structurally characterized in that a cylindrical steel roller is mounted on a steel shaft in a sleeved manner, and steel ringsfor fixing the steel roller sleeve two sides of the steel roller; mounting a ditching disc at a position, corresponding to the middle of a sowing ground ridge back, of a front crossbeam of a rack ofa film-mulching sowing machine, connecting two ends of the steel shaft at positions, 150mm away from the rear end, of longitudinal beams on two sides of the rack of the film-mulching sowing machine through hanging plates in a hanging manner, and enabling the ditching disc and the steel roller to be on a same straight line; starting the film-mulching sowing machine to work, wherein the ditching disc forms a microgroove in the middle of each ridge back, the steel roller rolls along the microgroove in the middle of each ridge back to compact and shape to form a ridge back microgroove, the ridge back microgrooves and planting ditches form a wavy rain collection terrain, and then the machine automatically completes film mulching, earthing and punch dibbling processes.

Description

technical field [0001] The invention discloses a multi-row mechanical film-covered sowing method of biodegradable water-seepage plastic film ridge back micro-grooves, and belongs to the technical field of crop farming and cultivation. Background technique [0002] Film mulching is a modern agricultural production technology, which has the functions of increasing temperature, heat preservation, water retention, nutrient retention, increasing light efficiency, improving soil fertility, inhibiting weed growth and shortening crop growth period, etc. It is an important drought-resistant and yield-increasing measure . The demand for plastic film in my country's agricultural production continues to increase. In the past two decades, the covered area and usage of plastic film have ranked first in the world. In 2016, the covered area reached 300 million mu, and the annual usage of plastic film was about 2 million tons. However, there are still some problems and defects in PE (polyet...
