不同灌水频率对辣椒生长效果的试验研究

Experimental Study on the Effect of Different Irrigation Frequency to the Growth of Pepper

为了探寻不同灌水频率对粤西主要北运蔬菜品种-辣椒的影响,选在粤西的化州市鉴江区柴脚岭建设农场内,进行大田试验。根据当地的灌溉习惯以及辣椒的需水情况,试验设定了4组不同的灌溉频率(每天灌1次,每2 d灌1次,每3 d灌1次和每4 d灌1次)进行对比试验。试验表明,辣椒总灌水量、产量、株高、茎粗、干物质等指标基本随灌水频率的提高而增加,但灌水频率为每2 d灌1次时辣椒产量最高。试验成果可为当地辣椒实施节水灌溉提供科学依据。

In order to research the effects of different irrigation frequency on the main varieties of pepper shipped to North Guangdong, a field experiment was carried out in the Jianjiang River District of Huazhou City Chaijiaoling construction farm in western Guangdong. According to the local irrigation practices and the need for water, 4 groups researches with different irrigation frequency （ 1 times per day, 1 times per day for 2 days, every 3 days for 1 times and every 4 days for 1 times） were done. The experimental results showed that the irrigation amount, yield, plant height, stem diameter, dry matter and other indexes of the pepper increased as increasing irrigation frequency, hut the highest yield is with the irrigation frequency 1 times per 2 days. The experimental results can provide scientific basis for the implementation of water saving irrigation in local pepper.
