一、不要盲目求新。每一个地区都有几个常规大量栽培品种,它们适应性强、高产抗病,很受市场欢迎。但有些菜农总认为卖新奇品种好。其实恰恰相反,没有经过试种的品种,极易失败。一般要自己已种过或看到别人种过多年的好品种才行。要种新奇品种,最好经过2~3年小面积试种后再大面积种植。二、不要盲目选购外地品种。品种有着较为严格的地区性。在甲地抗病高产是良种,到乙地可能就是多病低产的劣种。 First, do not blindly seek new ideas. Each area has several conventional large number of cultivars, they are adaptable, high yield and disease resistance, very popular with the market. However, some vegetable farmers always think that selling new varieties is good. In fact, on the contrary, it is easy to fail without the species tested. In general, you have already planted or seen good breeds that have been planted by others for many years. To a new breed of species, preferably after 2 to 3 years of small area after planting a large area planted. Second, do not blindly buy foreign varieties. Varieties have a more stringent regional. Disease resistance in high yield is a good seed, to B may be sickly and poor low-yielding species.
