作者从甜椒密度试验入手,调查了LAI和采收量的消长动态。结果表明,以4500穴产量最高,从其LAI理论曲线可知,该密度的现蕾、开花、始收、封垄期的适宜LAI值分别为0.15、1.16、3.87、5.OO。上述发育时期的LAI发育适合与否,均对产量有一定影响;LAI理论曲线有二方面的应用价值;一是检验栽培技术是否科学合理;二是提示改进栽培技术关键时期;据此提出夺取进一步高产的途径,一是充分利用适于甜椒生长的5、6月份,二是改善炎夏期间的小气候条件,使之主要发育时期的LAI尽量接近理论曲线。
The author started with the test of sweet pepper density and investigated the dynamics of LAI and the amount of harvest. The results showed that the highest yield was 4500, and from the LAI theoretical curve, the suitable LAI values for budding, flowering, initial harvesting and seal-up were 0.15, 1.16, 3.87 and 5.00, respectively. Whether the development of LAI in the above development period is suitable or not has a certain influence on the yield; the LAI theoretical curve has two application values; first, whether the cultivation technology is scientific and reasonable; second, it suggests that the key period of cultivation technology improvement is proposed; The first is to make full use of the sweet pepper growth in May and June, the second is to improve the microclimate conditions during the summer so that the main development period LAI as close as possible to the theoretical curve.
