The treatment effect ofJapanese translucent anti-insect netshed was the best, the treatment effectof ordinary anti-insect net shed rankedsecond, and the treatment effect of or-dinary plastic film greenhouse was thepoorest. Compared with open fieldcultivation, the Japanese translucentanti-insect net shed increased theplant height, leaf area and yield ofB. campestris by 22%, 63% and 49%,respectively.This study found that comparedwith the control, the other three treat-ments increased the Vc, soluble sugarand soluble protein contents of B.campestris. Miao et al.4found thatanti-insect net shed also increased thesoluble sugar content in B. campestris,in addition to reducing the applicationamount of pesticides and improvingthe yield of B. campestris, which wasconsistent with the results of thisstudy. In this study, the treatment ef-fect of Japanese translucent anti-insect net shed was the best, signifi-cantly better than those of ordinaryanti-insect net shed and ordinary plas-tic film greenhouse; no significant dif-ference was found in treatment effectbetween ordinary anti-insect net shedand ordinary plastic film greenhouse;and compared with those in open fieldcultivation, the Vc, soluble sugar andsoluble protein contents of B. campes-tris in Japanese translucent anti-insectnet shed were increased by 14%, 13%and 10%, respectively.In summary, Japanese translu-cent anti-insect net shed has obviouscomparative advantages in improvingthe yield and quality of B. campestrisin South China. In actual production, inaddition to research, development andpromotion of affordable and simple fa-cilities, the breeding of heat-resistantvarieties should also be strengthened.Screening heat-resistant B. campestrisvarieties through studying the effectsof high temperature on the growth anddevelopment, agronomic traits andphysiological indexes has a very im-portant significance on the productionof B. campestris. Studies have shownthat under high temperature stress, theyield, biomass, stalk quality and stalkleaf number of heat-tolerant B. cam-pestris varieties are higher than thoseof heat-sensitive varieties5-9.References1 ZHAI ZH (翟 志 宏 ), LIN ZG (林 鎮(zhèn) 國 ),CHEN HH (陳 慧 華 ), et al.

Rain and(Continued on page 2377)2356AgriculturalScience the increment of P concen-tration in leachate was 0.07-0.10 mg/Las phosphorus application rate was600 kg P2O5/hm2. Studies have shownthat phosphorus is the major limitingfactor for the eutrophication of fresh-water systems8-10. When total nitrogenconcentration in water is &gt;0.20 mg/L,orthophosphate concentration onlyneedstoreach0.01-0.02mg/Ltocausewater eutrophication11-12, thus damag-ing ecological environment and caus-ing pollution. Long-term excessive ap-plication of phosphorus fertilizer isbound to cause further loss of phos-phorus in sugarcane fields. However,nutrient uptake by sugarcane andphosphorus in crop residue and soilparticles taken away by surface runoffformed by rainfall erosion were ig-nored in the simulated rainfall experi-ment. The potential risk of phosphorusloss from surface soil (0-30 cm) wasexplored, so the study had limitations.In future research, field trials should becontinued to confirm the relationshipbetween phosphorus fertilizer, sugar-cane and phosphorus loss accordingto actual surface runoff and leakage ofphosphorus.The reasonable application rate ofphosphorus fertilizer for sugarcane is150 kg P2O5/hm2. However, long-termcontinuous application of phosphorusfertilizer can promote the enhance-ment of available phosphorus contentin soil and increase the risk of phos-phorus loss from sugarcane fields. Fu-ture research on the application ofphosphorus fertilizer to sugarcane andthe risk of phosphorus loss can beconducted around the increase of sug-arcane yield by phosphorus applica-tion, sugarcane planting years andavailable phosphorus content in soil.Based on available phosphorus con-tent in soil, the surplus of soil phos-phorus should be maintained in a rea-sonable range to reduce the risk ofphosphorus loss from sugarcane fieldsaccording to sugarcane planting yearsand yield targets.References1 JI HJ (冀 宏 杰 ), ZHANG HZ (張 懷 志 ),ZHANG WL (張 維 理 ), et al.
