Present Status Survey and Countermeasure of Applying Fertilizer to Main Vegetable Types in Anhui Province
HAN Shang, WU Ji, QIAN Xiao-Hua, GUO Xi-Sheng, HU Rong-Gen, DAN Meng-Chao, WANG Dao-Zhong
An investigation on vegetable fertilization in 2012 and 2013 was carried out in Anhui Province using sampling survey method，and the present status and existing problems of fertilization were analized and studied.The result indicated that there were 26 common vegetable species planted by surveyed househods in Anhui Province，among them 6 vegetables（pepper，tomato，cucumber，Chinese cabbage，cauliflower and eggplant） planted mostly by peasant households，were the main vegetable types in Anhui Province，which accounted for 52.1% and 67.4% of the total households number and vegetable acreage，respectively. Chemical fertilizers were applied in all farmlands，organic fertilizer only took 30.4%.The applications of nitrogen fertilizer all exceeded 300 kg·hm-2 in these 6 vegetables，and the average ration of N∶P2O5∶K2O was 1∶0.46∶0.49. There were big differences in organic fertilizer application among 6 vegetables.The average fertilizer applying frequency was 3.2 times in the whole vegetable growth period. The result also showed that cucumber yield was the highest，eggplant had the highest output value，and vegetable output value had significant positive correlation with fertilizer input. We should improve the current fertilizer applying technology，and speed up the application of soil testing and fertilizer recommendation technology in vegetable production.

Benefit-Cost Analysis Of Rural Household Planting Vegetables in Hainan Province——Based on Rural Household Survey from 6 Counties
LI Zhe-Min, ZHANG Yu-Mei, ZHANG Chao, XU Shi-Wei
This paper analyzes the production benift-cost for 5 vegetables： green pepper，cowpea， cucumber，bitter gourd and Chinese wax gourd based on the rural household survey data in Hainan Province. The paper also compares the above benift-cost with the cost and benefit of vegetable production in large and medium sized cities all over China，so as to understand the advantages and disadvantages of vegetable production in Hainan Province. The results show that：（1） Small households mainly depend on labor of family members at their own land to grow vegetables. Chemical fertilizers and pesticides are the major costs.（2） Production costs and benefits of different vegetable production are significantly different. The production cost of cowpea is the highest，that of green pepper，cucumber and bitter gourd follows；the cost of Chinese wax gourd is relatively lower，the input of pesticide and chemical fertilizer is less；while the net revenues of cucumber and Chinese wax gourd are relatively high.（3） The major advantages of planting vegetables in Hainan are lower production cost，and higher vegetable prices in winter.（4） However，compared with the national average level，vegetable yield per unit area in Hainan is still low. There are many difficulties in controlling pest and diseases. The paper suggests that the government should guide the farmers how to use pesticides and chemical fertilizer rationally，reduce costs and input，set up rands of their own agricultural products，and upgrade the products’ quality，etc. The paper also suggests the government to do more work to solve bottlenecks limiting vegetable industry development in Hainan，to further improve vegetable industry development level，and to increase farmers’ income as well.

Effects of Molybdenum Deficiency on Cold Resistance and Its Relationship with Antioxidant System in Cucumber Seedlings
CAI Huan, ZHU Shuai, NING Yu, WU Guo-Xiu, AI Xi-Zhen
In order to investigate the mechanism of molybdenum deficiency on chilling tolerance in cucumber（
Cucumis sativus
L.） seedlings，this paper takes‘Jinyou No.3’ cucumber seedlings as test material，and sets up 2 treatments：molybdenum deficiency（-Mo） and molybdenum application（CK）. The low temperature treatment （day/night temperature of 8 ℃ /5 ℃） was carried out in light growth chamber. The effects of molybdenum deficiency on chilling injury index，MDA content，antioxidant enzyme activities，and osmoregulation substances of cucumber seedlings were studied. The results showed that under low temperature -Mo treatment，the electrolyte leakage（EL），chilling injury index，and MDA content of cucumber seedlings were all significantly higher than that of the CK；while the activities of superoxide dismutase（SOD），peroxidase（POD），catalase（CAT） and ascorbate peroxidase（APX），and contents of glutathione（GSH），and ascorbic acid（AsA） in cucumber seedlings were significantly lower than that of the CK. The contents of proline，soluble sugar，soluble protein and free amino acids were all lower than that of the control. These results suggest that molybdenum deficiency aggravates chilling damage to the membrane，and reduces the cold resistance of cucumber seedlings. The reduction in antioxidant abilities and osmotic self-regulation of -Motreatment are the important reasons for cold tolerance weakening of cucumber seedlings.
