  Under the condition of long-term and fixed position nitrogen application in vegetable field, the variations of biomass, economic output and economic coefFicient of different type of vegetables were checked.The relationship between the variations and soil fertility were investigated.Models for output variations were estableshed in the experimental situation. Effect of the coordinated application of organic manure and nitrogen fertilizer on yield was remarkable. Based on the yield respose to fertilizing, vege...

  Effects of temperature and light on growth and yield of cucumber in winter was observed for 2 years. The results showed that under weak light and after artificial lowing stem into place, the leaf area of single plant of winter cucumber was fluctuated, the number of leaves was low and the nodes were long. The leaf area index was I～2.4 during fruiting season. The fruit of cucumber needed average of 27.9 days for growing from the middle of December to the middle of January. Average fruit weight was only 4.8lg/...

  Incidence, type, average grade and integrated index of malformed fruit of seven tomato varieties were compared. Among these varieties, Xifen No. 3 was the highest in the occurence of malformed fruit. Jiafen No. 10 and Shenfen No. 3 were high. Dongnong 704 and Zhongshu No. 5 were low. L-402 and liaofenza No. 3 were the lowest. In addition, the incidences of malformed fruit were higher in Xifen No. 3, Jiafen No. 10 and Shenfen No. 3,and the percentage of disorder fruit (seriously effected the properties of to...

  Intercropping spring cabbage with wheat, cabbage was in the shade of wheat and had poor ecological conditions with significantly low light intensity, soil temperature and high air humidity. As compared with single cropping cabbage, intercropping cabbage had the more rossette leaves and the fewer heading leaves, the lower photosynthetic rate, the less total dry matter accumulation and the ratio of dry matter distribution to heading leaves. The yield per 667m2 for intercropping cabbage decreased 25.7% than si...

  During 1994～1995, the yield of cucumber reached 356t per ha and the total income was 605 thousands yuan in the lean-to solar greenhouse of Mr. Wei GuoJun in Gu-an county. The five characteristics of the high yield was investegated, analysed and concluded as follows:Building the lean-to solar greenhouse such as Gu-an Ⅰ-type which has good heat preservation and ability of sunlight interception. Forming good soil granulation structure. Advancing the sowing time, selecting the strong grafted seedling. Strengthe...
