替代地膜覆盖的高稳定性杯罩结构设计与试验
Design and Experiment of a High-stability Cup Structure to Replace Plastic Film Mulching
摘要
Abstract
To address the limitations of traditional plastic mulch-including short lifespan,soil contamination from poor re-cyclability,a high stability cup cover was designed to meet the needs of tobacco seedling transplanting coverage and re-place traditional plastic film.Based on the theoretical analysis of multi-objective function optimization,and the principle of low center of gravity and strong stability,the shape of the cup was determined to be rounded.According to the growth status of tobacco seedlings at the later stage of transplanting,the height of cup was determined to be 20 cm.In order to meet the requirements of the top view extension area in the later stage of tobacco seedling transplanting,the radius of the upper port of the cup cover was determined to be 10 cm.Combined with the lateral bending condition of leaf shape in the later stage of tobacco seedling transplanting,the radius of the lower port of the cup cover was determined to be 7 cm.The reference cup cover need to meet the requirements of anti-deformation and light transmittance.The thickness was deter-mined to be 0.5 mm and the material was PP.The stability of the cup cover was verified by the maximum wind force and Rankine earth pressure method in the test area.The results of field tobacco seedling test showed that the above-ground growth of cup-covered plants was later than that of conventional plastic film mulching transplanting,the net photosynthetic rate,stomatal conductance and root development were better than those of conventional plastic film mulching transplan-ting,and the root-shoot ratio increased by 1.1%.Through the"micro greenhouse"effect,the internal humidity was kept in the range of 80%to 99%during the use period,and the temperature in the center of the lower port within 10 cm was 1 to 3 ℃higher than that of the plastic film mulching,which significantly improved the survival rate of tobacco seedling transplanting.Cup-cover mulching saved 650 RMB/hm2 per year compared with plastic film mulching.This study could provide reference for solving white pollution in the field.关键词
