The membrane potato is currently the most advanced high-yield technology in addition to shed cultivation. Through several years of production practice and research on agricultural technicians, it has been concluded that there are techniques and scientific measures for covering and decrepiting the membrane, and that good use has a positive impact on the improvement of monolithic production and the quality of chips。
Spectrum colour selection
The widespread introduction of white membranes over the years, which are luminous, luminous and aging-resistant, protects the meso-surface soil by increasing its temperature at about 3°c and contributes to the early seeding of potatoes, while at the same time increasing rapidly and contributing to the eradication of underground pathogens and eggs. However, due to their permeability, weed growth is also strong, consuming nutrients and moisture in the soil, competing with potato seedlings for water fattening, and affecting the normal growth of potatoes. The black membrane, however, is almost illuminating and the weeds cannot germinate for light cooperation, effectively inhibiting weed growth, avoiding weeds and potatoes for nutrients and reducing labour costs. However, black membranes reflect sunlight, the soil is warmer and more expensive than white membranes. In comparison with the two colour membranes, the option of black membrane cover may be considered to discourage weeds from competing for potato nutrients and moisture if there are more weeds. In general, however, more people choose white membrane cover。
Studies have shown that the warming effect of the different colour membranes is in the order of transparent membranes > green membranes > black membranes; 3 membranes have a significant protective effect, of which the membrane membranes differ slightly from the membrane membranes, and are slightly higher than green membranes; black membranes and green membranes have some weeding effects, with weeds having average resistance of 93. 7 per cent and 92. 1 per cent, respectively, and weed resistance of the membranes significantly above the membrane membranes of transparency, enabling them to control weed grass all the way without herbicides; the membranes covered with black membranes and green membranes have no late fertility periods, good seed quality, grassfruit, good quality, high yield, smoothing of potatoes, 80 per cent for large potatoes, 7. 0 per cent-1. 18 per cent for more transparent mems. As a result, more black membranes are currently used to reduce weed hazards。
In addition, in selecting the membrane, consideration must be given to the quality of the membrane, which should be of good quality, environmentally friendly, durable, non-light-exist, heat-resistant, stress-resistant and durable products, while ensuring that the membrane cover is flat and tight in order to create an environment conducive to the growth of potatoes。
Discovery time and management measures
The membrane potato evaporation, which improves the quality of production, is an increase that has been introduced in recent years. It is a matter of concern to most growers why they have to be exposed, and when they have to be able to manage them。
The first is to avoid the hazard of high temperature, which can be excessive in the membrane as temperatures rise, especially in the later stages of potato growth, affecting the normal growth of the plant and the growth of the tuber, which can help to avoid high temperatures. The second is to prevent excessive dampness of the soil and to avoid heavy submural wetness, which affects the quality of the roots of the breathing and tubing. Thirdly, the promotion of tubing expansion and maturity, closer to the natural state of the soil environment after the demolitions, and the temperature (16-20°c) required to meet the increase in the size of the chips, avoiding temperatures above 25°c, are more conducive to the full expansion and normal maturity of the tubing. Fourth is to reduce environmental pollution and avoid contamination of soil and the environment by residual membranes。
In addition, the time of defiling: the defiling time of membrane potatoes needs to be judged in the light of the growth phase of the potato, local climatic conditions and soil conditions. In general, it is more appropriate to remove the membranes when the chips are formed in the ground during the present period. It should be noted that in the case of low-temperature weather during the pre-growth period of potatoes, the release of the membranes may be delayed as appropriate; in the case of higher temperatures and higher soil moisture, the membrane should be removed as appropriate in order to prevent the adverse effects of high temperature and humidity on the growth of potatoes。
In any case, it is important to be flexible in terms of dyslexia, based on the principle of facilitating the growth and development of potatoes。
Finally, there are management measures for decrepit membrane: the first is a meso-pine weeding process, which increases the thickness of the soil around the roots of the plant and contributes to the abundance of potatoes. The second is the application of fertilization, combined with the planting of 30 pounds of compound fertilization per acre to supplement nutrients in the soil. Third, watering, depending on the soil's condition, fills the soil's moisture。
