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, a 25-acre 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 experiment with one film and four rows was carried out. 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 modul...

Abstract

A biodegradable permeable plastic film ridge back micro-groove multi-row mechanical film-covered seeding method, the purpose is to solve the problem of high-efficiency utilization of light rain resources and nutrients in dry land in semi-arid areas and the rapid rupture and disintegration of fully biodegradable plastic film at the seedling stage of crops; the present invention Invented first to make a steel roller suppression shaping module, its structure is to put a cylindrical steel roller on the steel shaft, steel rings for fixing the steel roller are set on both sides of the steel roller; A ditching disc is installed at the corresponding position in the center of the ridge on the sowing ground. Both ends of the steel shaft are hung on the two sides of the film planter frame at a distance of 150mm from the rear end of the longitudinal beams on both sides of the film planter frame through hanging plates. The ditching disc and the steel roller are located on a straight line; Start the operation of the film-laying seeder, open a micro-groove at the center of each ridge back with the ditching plate, roll and suppress the steel roller along the central micro-groove of each ridge back to form a ridge-back micro-groove, and the ridge-back micro-groove and planting ditch form a wavy set Rainy terrain, and then, the machine automatically completes the process of film laying, soil covering, and hole drilling.

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...
