It had proved that wheat cultivar Gaby is an important resistant resource to stripe rust.

小麦品种Gaby是重要的每锈病抗源品种，为了明确其抗锈遗传规律。

Aim at the influence factors about special field, cultivation system and cultivating level of rice in Shanghai farm, I studied characters of rice stripe blight occurrence on the Farm, investigated the disease resistance level and yield lose rate of different rice cultivars planted on the Farm, and made the suggestion about a synthetical control strategy for the disease in priority to adopt rice cultivars with resistance to the disease. Through investigation for the actuality of plant protection in Shanghai Farm and the examination of medicament for the disease, I gave an advice about the best chemical controlling method for the disease.

本研究的目的和方向：针对上海农场这一特殊地域因素、栽培制度、种植水平等因素的影响来研究农场水稻条纹叶枯病的发生特点；通过调查与试验上海农场不同品种的抗病性及产量损失，从而提出推广抗病品种的防治策略；通过调查与试验上海农场栽培制度下条纹叶枯病的发生特点，从而根据上海农场的特点提出综合防治的策略；通过对上海农场现有植保状况的调查与药剂试验，从而提出最佳化学防治方法。

Result The red-flowered strawberry variety Pink Panda had stronger adaptability to the low temperature range of-15~-20℃ and its LT50 was only 3.03℃ higher than that of L. perenne, so, its cold resistance was near to L. perenne and it could live through the cold winter in open field in mostly area in northern China.

结果］红花草莓品种&粉红熊猫&在-15~-20℃的低温范围内有较强的适应能力，与多年生黑麦草的半致死低温相差仅为3.03℃，说明该品种的抗寒性接近多年生黑麦草，能在北方大部分地区露地安全越冬。

The establishment of the technology of silkworm egg long-term storage and its application in commercial production will play an important role in strengthening the planning and controlling ability of silkworm production, in reducing economic losses caused by unbalanced supply and demand of silkworm eggs and the reproduction times of germplasm resources, in preventing race degeneration and in sparing expenditure of silkworm race conservation.

蚕卵长期保存方法的建立及实用化，对增强蚕种生产的计划调控能力，减少蚕种供需失衡造成的巨大经济损失；减少品种资源保存的饲养繁殖代数，防止品种退化，节省保种经费有重要作用，具有很好的推广应用前景。

Relay-planted with the same spring-sown maize, the quantity of nitrogen absorption of late maturity summer-sown maize was highest, but their nitrogen use efficiency was lowest, which because most the nitrogen absorbed were left in organs except grain.

与同一春玉米品种套作时，夏玉米为晚熟品种的吸氮量均较高，但其氮利用效率却较低，所吸收的氮更多的滞留在籽粒以外的植株器官中，向籽粒中转移的较少。

The results suggested that the activities of these enzymes quickly enhanced at 1 d, 3 d, 5 d and 7 d after inoculation by injecting conidia of the false smut fungus at 7-10 d before heading in the resistant cultivars, but slower increase in the susceptible cultivars, and also showed that there was correlations between the cultivar resistance to the disease and the three enzymes.

结果表明，在抗病品种中苯丙氨酸解氨酶、过氧化物酶和多酚氧化酶3种酶活性接种后迅速提高，变化幅度较大；而感病品种的酶活性在接种后缓慢增加，变化幅度小。由此说明，这3种防御酶与水稻抗稻曲病有一定的关系。关键词水稻；稻曲病；防御酶

Application of the correct amount of master general, the hybrid rice potassium need more potassium to be less conventional rice; late potassium need more rice to be less potassium; potassium tall varieties need more potassium to be less short-stalked varieties.

正确掌握施用量一般来讲，杂交稻需钾较多，常规稻需钾较少；晚稻需钾多，早稻需钾少；高秆品种需钾较多，矮秆品种需钾较少。
