Cress is one of the Jiangsu Province cultivated aquatic vegetables, in recent years, as consumers increase the awareness level of health vegetables, cress cultivated area of ??the province in Southern Jiangsu Province represented by the Yangtze River Delta expanded rapidly. Wet planted cress as a rich nutritional value, better health care therapeutic efficacy and unique flavor characteristics of vegetable pests and diseases rarely, and almost no pesticide use, adaptability, simple cultivation techniques save labor and water, and high yield. Therefore, the development of cress production potential great application prospects are very bright. The domestic research about cress few relatively few in-depth studies on wetlands planted cress. The test wet planted the cress different cultivation measures to study the law of growth and its impact on the quality, look forward to the development of wet planted cress high yield and quality cultivation technology services to producers. Leafy vegetables harvested period, mature no clear boundaries, explore the the rough old key indicators of cress taste by measuring different harvest fiber component content change, so as to wet planting cress quality research to provide technical data . This thesis is to Jiangyin wet planted cress as test material, to study the different ways of transplanting, cultivation methods, harvest stubble on the cress yield, quality, draw the following main results: a wet-planted cress transplanting period requirements are not strict, the stubble arrangement is relatively flexible, and easy implementation of crop rotation with other crops. Spring single-crop harvest petiole main edible organs, fall transplanting 10cm spacing, the transplanting time should be no later than the end of November. Transplanting 11-20 handling Dropwort lobules highest vitamin C, soluble protein, chlorophyll, mannitol content, mineral elements K, Ca, Mg, Fe highest content. If the implementation of a quarter of the multi-crop harvest, and even the higher nutritional value of lobular eat together, being suitable for transplanting density, early transplanting can be picked early, multi-crop harvest. The more 2 wet planted cress lobular its mineral elements, the overall health ingredients above petiole. Show that wet planted cress higher nutritional value, lobular significantly better than the petiole, recommended even lobular with food. Different cultivation processing of wet plant nutrition and health products cress ingredients have some degree of influence, but overall have higher levels of flavonoids, dietary fiber content, total dietary fiber content ranged from less crude fiber content ranged from larger speculated that the crude fiber content is the affect product taste coarse old key indicators. 3 wet planted cress on the K fertilizer demand for larger, K fertilizer insufficient cause decline in yield, quality. The wet planting cress growth process to be appropriately increased K fertilizer. Different transplanting the first crop of products, for example, the the per acre Tian purpose production in the range of 3000 ~ 6500kg takes about N: 9.72 to 19.8 kg P2O5: 2.28 to 13.5 kg, K2O: 18.02 to 30.21kg.
