甜瓜与红薯套种栽培技术,实现二者双重丰收,经济效益显著。据样本统计,每667平方米种植青皮甜瓜产量1600千克左右,红薯产量在2500千克左右,总产值在7000元左右。比种植粮食收入提高了5~6倍,主要栽培技术如下。一、如何整地1.年前不施任何肥料,把土地深翻一次,深度在25厘米左右,只耕不耙,以利于冻死部分过冬害虫及杂草,减少病害。2.立春后开始施肥浅耕及时保墒,每667平
Melon and sweet potato intercropping cultivation techniques to achieve double harvest of both, significant economic benefits. According to the sample statistics, about 1,600 kg of sweet melon is planted every 667 square meters, about 2,500 kg of sweet potato is produced, and the total output value is about 7,000 yuan. Compared with planting grain income increased by 5 to 6 times, the main cultivation techniques are as follows. First, how to site a year ago without any fertilizer, the land deep plowing a depth of about 25 centimeters, only tilling does not rake, in order to facilitate the freezing of dead pests and weeds to reduce the disease. 2. Beginning spring fertilization shallow tillage in a timely manner soil moisture, every 667 level
