马铃薯秋薯春播具有种性好,退化轻,植株生长健壮,产量高等优点。因此我国南方不少低海拔高温地区,春薯春播无法保种的品种,采用秋薯春播就能较好地保持种性。但由于马铃薯作物对环境条件敏感,且品种间差异较大。从我省看,秋薯春播问题在高山、二高山、丘陵、平原地区反应就颇不一致。一般高山反应好,二高山次之,低山、丘陵、平原地区问题较多,有些地方甚至认为秋薯不能作种,主要就是因为秋薯春播产量不稳定。怎样才能使秋薯春播高产稳产?根据我们多年试验结果认为,要解决这个问题,必须掌握秋薯春播的生长发育特性,从中找出影响产量的主要问题及解决途径,并落实在有效的栽培技术措施上。 Autumn potato spring sowing has good sex, light degradation, robust plant growth, high yield. Therefore, many low-altitude areas in southern China, spring sowing can not be sown varieties of spring sowing, spring sowing will be able to better maintain the species. However, due to the environmental sensitivity of potato crops, and large differences between varieties. From our province, autumn spring sowing problems in the mountains, mountains, hills, plains, the response is quite inconsistent. Generally good alpine response, second highest in the mountains, low mountains, hills, plains more problems, and some places even think autumn can not be planted, mainly because of the unstable yield of autumn spring sowing. According to our years of test results, to solve this problem, we must grasp the growth and development characteristics of autumn sowing spring, find the main problems affecting production and solutions, and implement the effective cultivation techniques Measures.
