摘　　要：为研究气象条件对辣椒分期播种产量和品质的影响,2021年在凤冈县农业气象园区以遵辣9号为试验对象,分7期进行辣椒播种育苗移栽对比试验。通过对比和相关性分析得出:遵义辣椒适宜育苗期在2月至3月上旬,超过3月下旬产量则下降明显,且播种延后,最佳轮次采收期即5轮次之前采收的辣椒,在7月下旬至8月期间遇夏伏旱影响较大。开花始期至采收期,≥10℃积温与二氢辣椒素含量呈显著的正相关,说明积温对辣椒品质有一定影响,≥10℃积温越多,二氢辣椒素含量越高,辣椒整体辣味和口感就越好,辣椒品质就越好;日照时数与粗脂肪含量呈显著正相关,说明充足的光照影响品质,日照时数越大,粗脂肪含量越高,粗脂肪含量高则辣椒的适口性和香味就越好。因此,辣椒整个生育期因播期、气象条件不同,对各品质指标影响的程度也不尽相同,抓住辣椒特性合理播种,对提高辣椒产值和提升品质、口感至关重要。In order to study the effect of meteorological conditions on the yield and quality of pepper sowing in stages,a comparative test of pepper sowing and seedling transplantation was carried out in Fenggang County Agro-meteorological Park in 2021 with Zunyi Hot No.9 as the test object in 7 stages.Through comparison and correlation analysis,it was concluded that:Zunyi pepper suitable seedling period in February to early March,more than the second half of March,the yield will decline significantly,and sowing delayed,the best round of harvest period that is the best round of 5 rounds before the harvest of the pepper,in late July to August in the period of summer drought has a greater impact.From the beginning of flowering to harvesting,≥10℃accumulation temperature and dihydrocapsaicin showed a significant positive correlation,indicating that the accumulation temperature has a certain effect on the quality of chili peppers,≥10℃accumulation temperature,the higher the dihydrocapsaicin,chili peppers overall spiciness and taste,the better chili peppers quality;the number of hours of sunshine and the crude fat content showed a significant positive correlation,indicating that the quality of the impact of adequate light,the greater the number of hours of sunshine,the higher the crude fat content,the higher crude fat content of the palatability of chili peppers,and the higher crude fat content,the higher crude fat content,the higher the palatability of chili peppers.The higher the crude fat content,the better the palatability and flavor of chili.Therefore,the whole reproductive period of chili peppers,depending on the sowing period and meteorological conditions,have different degrees of influence on the quality indexes,and it is crucial to grasp the characteristics of chili peppers and rationalize the sowing to improve the output value of chili peppers and enhance the quality and taste.
