优良品种是夺取丰收、扩大再生产的重要条件。好种出好苗,好苗收成高。选用丰产、抗灾能力强的良种是获得高产稳产的前提。良好的栽培条件只有配合优良品种才能获得高产。因此,我们在选择良种时,首先要因地制宜,按照当地的气候、土壤肥力和栽培条件等具体情况进行选择。水肥条件较好的地区用耐肥抗倒的高产品种;土壤肥力差无灌溉条件的地区,应选留抗旱耐瘠薄的品种;有盐碱的地区应选留抗碱耐盐的品种;干热风易发生区选用早熟抗干热风的品种;
Good variety is an important condition to seize good harvest and expand reproduction. Good kind of good seedlings, seedlings harvest high. Selection of high yield, strong ability to resist the disaster is the premise of high and stable yield. Good cultivation conditions can only be achieved with high quality varieties. Therefore, when we choose good varieties, we must first make our own choice according to local conditions, according to local conditions, soil fertility and cultivation conditions. In areas with better water and fertilizer conditions, high-yielding and high-yielding varieties should be used in areas where soil fertility is poor and irrigating conditions should be reserved for drought-resistant and barren varieties. In areas with saline-alkali soil, salt- and alkali- Prevailing areas prone to selection of varieties of anti-dry hot air;
