First, the rapeseed film on the seedlings cultivation selection of a 40 cm wide mulch film, after ridging film, and then on the film by spacing 50 cm, spacing 13.3 cm perforation hole sowing, leave 10,000 per acre seedlings. The filming on the mulching film has a good effect on warming and maintaining mulch because of the large area of ​​the mulching film. It can well improve the water and heat conditions in the field and better coordinate the production elements of rapeseed and the capacity of rhizosphere for soil water storage and water supply. Second, rapeseed plastic film side groove sowing cultivation selection of 40 cm wide mulch film, after ridging film, ridge centerline distance 50 cm, in the middle of the two films to open a ditch planting a row of rape, plant spacing of 13.3 cm, per acre Liu Miao 10,000 strains. Rapeseed mulching on the mulching side of the rapeseed has good air permeability, significant water collection effect, easy operation, and labor saving and time saving. However, in the dry period, its conservation effect is worse than that on the membrane. Third, the rapeseed mulch within the first sowing cultivation trenches ditch, ditch 10 cm deep, two ditch 50 cm apart, sowing the ditch, leaving 10,000 per acre seedlings. After the wintering of the rapeseed, the 140-cm-wide plastic film was used to cover the seedlings, and holes were drilled every 20 centimeters on the film and the hole diameter was 3 centimeters. After the rape returns to green in spring, the seedlings are gradually unrolled until the film is completely removed. This method is complex in operation, and if the locust control is not timely or incomplete when it is covered with film before winter, it is easy to cause diseases, resulting in a significant reduction in production, which is not conducive to large area applications.

The body produces carnitine in the liver and kidneys and stores it in the skeletal muscles, heart, brain, and other tissues. But its production may not meet the needs under certain conditions such as increased energy demands and therefore it is considered a onditionally essential nutriention. There are two forms (isomers) of carnitine, viz. L-carnitine and D-carnitine, and only the L-isomer is biologically active.
