水稻塑盘浆播旱育秧技术优势及操作要点 总被引：1，自引：0，他引：1
水稻塑盘浆播旱育秧是利用菜园地、幼龄果园、房前屋后空地等旱地作为秧地 ,以肥沃的塘泥、沟泥作营养土 ,播种后水的管理采用旱育秧管水法。这一育秧方式自１９９８年在福建漳浦试验示范以来 ,深受当地农民欢迎。尤其是漳浦县沿海乡镇 ,由于冬种面积大、粮经用地矛盾突出、秧地难寻、劳力紧张等因素 ,严重制约了水稻抛秧技术的迅速普及。水稻浆播旱育秧技术的推广 ,大大缓解了这些矛盾 ,拓宽了抛秧的应用范围 ,加速了抛秧推广速度。漳浦县１９９８～２００１年累计推广水稻浆播旱育抛秧面积达１．５万ｈｍ２ ,平均单产４８５．４ｋｇ／６６… 相似文献

晚稻塑盘旱育抛秧苗期喷施 总被引：1，自引：0，他引：1
多效唑是一种高效植物生长调节剂,广泛应用于杂交中、晚稻水育秧,其主要作用是有效控制秧苗高度,促进根系生长和提高低节位分蘖,增加叶绿素含量,达到培育壮秧、增产的目的。但多效唑在晚稻塑盘旱育抛秧中试验和应用,则处于起步阶段,目前试验研究报道尚少。 湖北省监利县双季晚稻育秧期间高温、多雨,秧苗生长快、易徒长,尤其是塑盘旱育抛秧播种密度增大,秧苗更易徒长成高脚弱苗,不利于抛栽和立苗。因此,晚稻塑盘旱育抛秧在培育壮秧上控苗是关键。我们就晚稻塑盘旱育抛秧施用多效唑的控促效果及其对秧苗素质和产量的影响做了试验,现将试验结果介绍如下： 相似文献

Sorghum is a good source of phenolic compounds with a variety of genetically dependent types and levels including phenolic acids, flavonoids, and condensed tannins. Most sorghums do not contain condensed tannins, but all contain phenolic acids. Pigmented sorghums contain unique anthocyanins that could be potential food colorants. Some sorghums have a prominent pigmented testa that contains condensed tannins composed of flavan-3-ols with variable length. Flavan-3-ols of up to 8–10 units have been separated and quantitatively analyzed. These tannin sorghums are excellent antioxidants, which slow hydrolysis in foods, produce naturally dark-colored products and increase the dietary fiber levels of food products. Sorghums have high concentration of 3-deoxyanthocyanins (i.e. luteolinidin and apigenidin) that give stable pigments at high pH. Pigmented and tannin sorghum varieties have high antioxidant levels that are comparable to fruits and vegetables. Finger millet has tannins in some varieties that contain a red testa. There are limited data on the phenolic compounds in millets; only phenolic acids and flavones have been identified. 相似文献

Summary Between 1993 and 1998 205 different potato cultivars and 1220 accessions/genotypes of wild and cultivated potato species from
the IPK Genebank Gatersleben were evaluated. Parameters interesting for starch isolation and especially for the use of starch
were determined. Altogether, there was a higher variability in wild potato species than in cultivated potatoes for all characteristics
investigated: dry matter content, starch content, protein content, amylose content and mean particle diameter of starch granules. 相似文献

In field experiments conducted over 2 years in Mediterranean conditions, five winter and five spring triticales were evaluated for forage and grain production in the same cropping season. The experiments had two treatments, namely harvesting for grain only, and dual-purpose forage and grain production. In the latter treatment, forage was cut when the first node was detectable (Zadoks' stage 31), without removing the apical meristems. Grain was harvested when ripe (Zadoks' stage 92) in both cut and uncut plots.
Environmental conditions affected grain production and protein content more than forage yield and quality. Winter triticales yielded about 43% more forage than spring types, but after forage removal the spring types yielded about 36% more grain than winter triticales.
Reductions in grain yield after clipping were more pronounced in winter (32%) than in spring (19%) types. Forage crude protein content was significantly higher in the spring types studied (24.6%) than in the winter types (23.5%), the opposite being true for fibre content (20.7 and 21.6% respectively). Grain crude protein content did not differ between grain and dual-purpose treatments, but was higher in the spring triticales (12.8%) than in the winter types (11.9%). There was more variability for the measured traits within the winter triticales studied than within the spring types. 相似文献

Summary Arbuscular mycorrhizae were inoculated into phosphorus-deficient soil fertilized with either organic or chemical fertilizer with cucumber (Cucumis sativus L.) as the first crop and lettuce (Lactu-ca sativa L.) as the second crop but without additional fertilization and AM inoculation. AM increased dry matter and fruit yield of cucumber significantly in the unfertilized, organic-fertilized and P-deficient plants compared with the fully chemical-fertilized plants. AM inoculation increased the available phosphorus in plant and soil by around 30% for all treatments except for those chemically-fertilized. The rate of AM infection did not differ significantly among the fertilization treatments, but the infection intensity was higher in unfertilized, organic-fertilized and phosphorus-deficient treatments than chemical-fertilized treatment. The residual effects of AM-inoculated to cucumber were evident for lettuce in all pre-treatments that were unfertilized and un-inoculated for the second cropping. Without P-fertilization, neither crop could grow optimally even when the soil was inoculated with AM, suggesting that AM could not serve as a substitute for phosphorus fertilizer. However, the other beneficial effects of AM on crop growth and yield could not be fulfilled with phosphorus fertilizer. 相似文献
