甘草栽培技术 总被引:2,自引:0,他引:2
甘草别名甜草根,属多年生豆科草本植物。甘草全身为宝,地上部分是畜牧业的良好饲草,地下根和茎可入药,甘草对土质要求不严,并能起到防风固沙的作用。在退耕还林还草的种植业调整机遇中,本团已人工种植甘草800hm2。现将甘草栽培技术介绍如下。1种子处理甘草种子坚硬光滑,外有一层胶质物,种皮不易透水透气,硬实率较高。未处理的种子发芽率仅有10%~20%,通过处理可显著地提高发芽率达80%以上。1.1硫酸法处理每50kg种子,加80%浓硫酸1000ml,用木锹或方锹拌匀磨锉15min,再闷种30min,将种皮胶质层烧裂变粗糙后,用清水反复冲洗种皮上的硫酸,待种皮未… 相似文献

黄连种子后熟处理及与玉米套作栽培技术 总被引:2,自引:0,他引:2
1种子后熟处理
黄连种子有胚后熟和休眠的特性.种子收获时期的种胚尚未发育好,需贮藏于5~10℃低温处经180~270d可使种子的胚慢慢发育长大,完成胚的分化.从外形上看,种子已裂口,此阶段称形态后熟,但这时播种仍不能发芽,必须在0~5℃低温贮藏30~90d,才能完成生理后熟阶段,种子才能正常发芽.在自然气温下的湿种子(干燥的种子就失去发芽力),需经150~180d的自然温度,90~120d的自然低温(冬季),才能完成胚的后熟阶段,种子播后才能正常出苗. 相似文献

中国北方地区花生栽培技术的研究进展 总被引:8,自引:0,他引:8
花生属地上开花地下结果的少数作物,其栽培条件对其产量影响尤为显著。花生新品种对产量的贡献率占20%—30%左右,而栽培技术对产量的贡献率达70%左右。随着种植制度的变革和市场发展的需求,花生栽培技术研究取得了较大进展。本文总结了近50年来北方区花生栽培技术的主要研究成果,目的在于为花生生产的发展和栽培技术的研究提供参考。 相似文献

温度上升对中国茶树栽培北界的影响 总被引:4,自引:0,他引:4
以茶树栽培北界变化为研究对象,根据对中国未来温度变化的模拟结果,研究了未来中国茶树栽培北界的变化。目前中国茶树栽培北界大致位于秦岭-淮河,又可分为东西两段:西段为秦岭山地,由于地形作用栽培界线稳定;东段为平原丘陵,随气候冷暖变化栽培界线变化较大。根据温度变化预测,未来西段茶树适宜栽培界线仍然较稳定,而东段的北移明显,2050年将可能从目前界线向北推移153~251km,2090年可能向北推移290~477km。 相似文献

It has been argued that the breeding of cultivars with higher weight per panicle but constant phytomass (i.e., improved harvest index) is unlikely to improve grain yield of cereals in the future. To examine this question in oats, this study observed relationships between above-ground phytomass production and grain yield as well as 18 morphological and physiological traits representing maturity class and architecture of oat stand. The study was conducted in two dissimilar growing seasons. Material consisted of 29 Finnish and Scandinavian oat cultivars and breeding lines. Correlations between phytomass and other traits were evaluated by linear regression analysis. The study revealed that there has already been a trend toward improving the above-ground phytomass production in cereal breeding in Finland. The phytomass elevation can be attributed to both higher panicle weight as well as increased above-ground vegetative phytomass. Thus, improved grain yield of oats is not merely a consequence of increased harvest index, as is often mentioned, but is also a result of higher phytomass as such. The weight of the above-ground phytomass did not correlate with undesirable traits such as plant height or susceptibility to lodging, but it did have a positive relationship with days to yellow ripening. The applicability of phytomass weight in indirect yield breeding of oats in the northern growing conditions is discussed. 相似文献

1制定规划,规模种植
根据国家和地方对各类不同品质小麦的需要,建立不同品质类型的优质小麦生产基地.如:面包、面条和馒头专用型小麦应在土壤氮素水平较高、土质偏粘的淤土、砂浆黑土和中壤土集中的地区种植;饼干、糕点专用型小麦应在沙质土壤集中的地区发展. 相似文献

Overgrazing in the grasslands of Inner Mongolia following market reform in China has led to severe soil degradation and desertification. In an effort to revive the ecological environment in northern pastoral areas, the government of China recently adopted an intervention policy to relocate families from areas where excess grazing pressure was seriously compromising land and the environment. A survey was conducted in three villages to determine how well the relocated families have adapted to their new living conditions and the factors that affect their willingness to stay in the new villages. Regression analysis revealed that the most important factors were age of the head of the household, length of time the family has resided in the new village, proportion of total income that is made up of government payments and level of fixed, durable and current assets. 相似文献
