1. Difference in sowing date influences the development of winter wheat. The earlier the sowing, the earlier is the completion of the thermostage. The length of the thermostage of early sowing wheat is longer than that of the later sowing wheat. The length of photostage is affected in the opposite manner. 2. Differentiation of the growing cones of early sowing wheat is faster than the later sowing wheat, but the differences became smaller as growth proceeded. 3. Early sowing produces...

1. Difference in sowing date influences the development of winter wheat. The earlier the sowing, the earlier is the completion of the thermostage. The length of the thermostage of early sowing wheat is longer than that of the later sowing wheat. The length of photostage is affected in the opposite manner. 2. Differentiation of the growing cones of early sowing wheat is faster than the later sowing wheat, but the differences became smaller as growth proceeded. 3. Early sowing produces different effects on the development stages and the differentiation of the growing cone. Thus, winter wheat might complete the photostage while the growing cones were in the double ridge stage. 4. A discussion on the relation of the differentiation of growing cones and the development stages, also on the influence of sowing date to the yields were presented.

1.播种期影响了冬小麦在秋播条件下的发育特性。播种期早,春化阶段和光照阶段早结束。在田间春化阶段渡过的天数早播的长而晚播的短;光照阶段则有相反趋势。 2.早播种,冬小麦的生长锥分化进程比晚播的提前。生长锥分化各时期的差异随着植株的生长而逐渐减小。 3.提早播种对冬小麦的发育阶段和生长锥分化产生不同程度的影响,以致光照阶段结束时生长錐分化时期是在二棱后期。 4.本文对小麦生长錐分化和发育阶段的关系,播种期对产量构成因素的影响进行了讨论。

The wheat plants subjected to a moderate soil drought at seedling stage gave a greateryield either under full water supply condition or exposed once again to the drought at bootingstage.The rate of drying and the extent of dryness all affected the hardening effect.It seemsthat a relatively long period was necessary for the repair of damage by the drought.An op-posite result was obtained with spring sowing wheat plants because their growth period wasso short that the plants entered reproductive growth before they could recover from the damageinflicted on the plants during drought treatment.The plants that had been hardened at seedling stage grew afterwards much better thanthe nontreated plants:the root system renewed and enhanced,the leaf-area of the upmost threeleaves enlarged,the chlorophyll content increased and the rate of accumulation of dry matteraccelerated.A greater ratio of free water to bound water content was observed in such harden-ed plants.Under drought condition the hardened plants were distinguished by heightened intensity ofwater metabolism.They showed a greater water content(especially free water)and alower water deficit.The permeability of protoplasm of hardened plants was less susceptibleto the injury from drought than that of control plants.They also exhibited a greater abilityto withstand dehydration.Thus the increased drought resistance of hardened wheat plantswas not only due to avoidance,but also tolerance.

小麦在苗期经受适度的干旱处理以后,表现了显著的煅炼效果。本文探讨这种苗期干旱煅炼成功的关键,并指出煅炼后提高抗旱性的原因,不仅是对干旱的“避免”,而且还由于对干旱的“忍耐”。

The oscillating rod type seed-metering device is developed from the working principle of "Lou"-a plowlike Chinese traditional implement for sowing. It has compact and metal saving structure, and can be used for drill seeding of different crops such as wheat, sorghum, corn, millet, rape, pea, Chinese cabbage, radish, scallion, alfalfa, etc. In compare with the external force feed type, the uniformity of dropping may be increased by 10-30% when sowing wheat, sorghum, millet and corn. When sowing small...

The oscillating rod type seed-metering device is developed from the working principle of "Lou"-a plowlike Chinese traditional implement for sowing. It has compact and metal saving structure, and can be used for drill seeding of different crops such as wheat, sorghum, corn, millet, rape, pea, Chinese cabbage, radish, scallion, alfalfa, etc. In compare with the external force feed type, the uniformity of dropping may be increased by 10-30% when sowing wheat, sorghum, millet and corn. When sowing small grain seeds, the sowing rate can be controlled at 7.5kg/ha or less with better uniformity and lower percentage of breakage, showing its unique superiorities.This article deals with a primary analysis and approach about the kinematic calculations, working principles, dropping characteristics, and the choice of parameters of the oscillating rod type seed-metering device on the basis of a great deal of experimental data.

摆杆排种器是根据我国传统农具——耧的工作原理,研制成的一种排种器。它的结构紧凑、金属耗量小、能条播多种作物。例如小麦、高粱、谷子、油菜、豆类、白菜、萝卜、大葱、苜蓿、沙打旺等。它和外槽轮式排种器相比,在播种小麦、高粱、谷子和玉米时,其排种均匀性提高10~30%左右。尤其是在播种小粒种子时,不仅能把亩播量控制在一斤范围内,而且均匀性好、破碎率小,显示出其独特的优点。 本文根据大量试验数据,对摆杆排种器的运动学分析、工作原理、排种性能以及参数选择、结构设计进行了初步分析和探讨。
