Description

Laminating machine with small steering radian

Technical Field

The utility model relates to the technical field of agricultural equipment, in particular to a film laminating machine with small steering radian.

Background

The ridging cultivation is frequently adopted for planting part of potatoes, beans and vegetables, the ridging cultivation can improve the ground temperature, preserve water, preserve fertilizer and increase the crop yield, and the ridging cultivation is often matched with mulching films, so that the furrowing and ridging mulching films can effectively save water resources, reduce the irrigation times, further preserve water and increase temperature, avoid rainwater from scouring the ground or cause soil hardening, and reduce the workload. Mulching cultivation, namely covering the ground with a transparent plastic film, sowing under the film and protecting the growth of crop seedlings, and uncovering the film after the air temperature is warmed so that the seedlings grow under normal climatic conditions. The measures have the effects of increasing temperature, preserving soil moisture, increasing production and increasing income in low-temperature cold and cold areas with insufficient heat. Generally speaking, the growing season of crops is prolonged by 20-30 days. The ground temperature of 0-5 cm in the film is increased by 2-4 ℃ in winter and spring, the temperature of the near stratum is increased by 4-8 ℃, and the ground temperature in the film can be reduced in hot summer. The film covering reduces the evaporation of soil moisture and also has the effect of water storage and soil moisture preservation. The fertilizer applied to the soil under the protection of the mulching film can not be lost due to wind, sun and rain, and the growth of weeds can be effectively controlled. The colorless film has strong capability of reflecting light, can increase 10% of sunlight at a height of 15 cm from the ground, and improves the photo-thermal condition of an air layer close to the ground. The film mulching cultivation also promotes the activity of soil microorganisms, accelerates the decomposition of organic substances, improves the physical and chemical structure of the soil and creates a suitable ecological environment for the growth of crops. Crop film mulching cultivation becomes an important measure for increasing the yield of agriculture in the world, but China is about to develop the fastest, the largest and the best effect. The mulching cultivation in China is developed from cold areas to suburb plains, and is expanded from fruit and vegetable crops to grain and cotton crops, so that the labor efficiency is obviously improved, the land is saved when the crops are taken urgently, the investment is low, and the benefit is high. The wild goose is in a cold and cold northern region, the climate is cold, the growing period is short, the wild goose is an 'forbidden region' for corn production for a long time, the corn cannot be matured in the annual field, the effective accumulated temperature is increased after the mulching cultivation is adopted, and the corn can be matured safely in the local area. The dry farming area in Gansu province adopts the wheat mulching hill-drop technique, solves the problems of water shortage and insufficient heat, and realizes water-saving and temperature-increasing high-yield cultivation.
