一、栽培技术(一) 耕作制度:不能連作,連作不仅产量低、根長不大,而且品質不好,病虫多,故应实行3—5年輪作制。前作以豆科作物为好,后作小麦紅茹等。产区習慣在头年间作辣椒、茄子、油菜、烟草等,其中以間作烟草、茄子等較差,最好不间作。(二) 选土整地:选疏松肥沃、土層深厚的帶砂的壤土(农民叫大岩黄土或灰巴土)。黑砂土栽的心大皮薄。夾泥土、粘重土栽的根細,而分枝多,又易發爛。在不妨碍前作生長的情况下,尽量提早整地,尤以挖伏土最好。挖时先挑生黄土一層拌翻,深約1.5尺,打碎整平,即可栽植。
First, the cultivation techniques (A) Tillage system: can not be continually cropping, crop production is not only low, root length is not big, but the quality is not good, pests and more, it should be implemented 3-5 years rotation system. Leguminous crops before as well, after the wheat red Ru and so on. Producing areas used to be in the first year as peppers, eggplant, rape, tobacco, etc., of which intercropping tobacco, eggplant and other poor, it is best not intercropping. (B) the election of soil preparation: Select loose and fertile, deep soil with sandy loam (farmers called rock loess or ash soil). Black sand soil planted big thin skin. Folder soil, stick heavy soil planted root thin, and more branches, but also prone to rotten. Without prejudice to the growth of the former case, try to cut the soil early, especially in the best volcanic soil. Loosen the first loess loess when the first layer of mixed turn, about 1.5 feet deep, broken flat, you can plant.
