Three experimental fields f seawater rice were harvested in China n Wednesday, a further step tward its future practical use.Als knwn as saline­alkali tlerant rice (耐盐碱水稻), the seawater rice is designed t grw in seaside flats r ther areas with high salt cntent and has been develped by experts thrugh crssbreeding (杂交) and ther technlgies.
One type f seawater rice grwing in Qingda's Chengyang district, Shandng Prvince，prduced 3.9 metric tns (公吨) per hectare (公顷), experts annunced.Once widely planted in large areas, the utput culd be much higher.
The Qingda Saline­Alkali Tlerant Rice Research and Develpment Center, led by renwned Chinese agricultural scientist Yuan Lngping, was established several years ag.It set itself a three­year target f develping a kind f salt­resistant rice capable f prducing 4.5 tns a hectare, which wuld guarantee grwers the minimum acceptable level f prfit.The average rice utput in China is 6.75 tns a hectare.
Planting in the experimental field in Chengyang district and five ther plts f saline­alkali land started at the end f May.The five ther plts were in Dngying, Shandng Prvince；Wenzhu, Zhejiang Prvince；Yan'an, Shaanxi Prvince；Kashgar, the Xinjiang Uygur Autnmus Regin；and Daqing, Heilngjiang Prvince.The sites represent actually every type f saline­alkali land in China and researchers aim t grw different kinds f rice able t cpe with different climate, salinity and sil structure cnditins.
The test crps in Kashgar and Daqing were als harvested n Wednesday.In Kashgar, the utput reached mre than 7.5 tns per hectare, accrding t experts' tests, much higher than expected.The harvest in Kashgar was satisfactry.The result means it is pssible t plant such salt­resistant rice in suthern Xinjiang in the future.Xinjiang has abut 2 millin hectares f saline­alkali land that have the ptential t be planted with salt­resistant rice, and if it is widely planted it will generally imprve rice prductin in the regin.
The seawater rice grwn in Daqing nly prduced 3.1 tns per hectare.A live vide n Shandng TV shwed grwers appearing a little disappinted by the result, as they hped the experts' effrts wuld increase prductin greatly.The water and sil cnditins f the site were nt ideal, and the PH level was extremely high.

When lking at academic rigr (严谨) as an indicatin f “fit”， yu are likely t find that yu have the capacity t “get the jb dne” academically in a range f cllege envirnments.In ther wrds, yu are nt likely t have difficulty with the “water” itself.Yu will fit best, hwever, at clleges and universities where yur ability and preparatin enable yu t rise t new levels f challenge.Yur gal shuld be t find academic envirnments where yur levels f ability and preparatin will enable yu t achieve well as yu stretch yurself intellectually.
The best surces f insight regarding yur preparedness t meet the academic standards f varius clleges and universities are yur high schl teachers, because they are familiar with yur capabilities, and they can ffer invaluable advice abut identifying the clleges where yu will find the best academic prgrams fr yu.
Assuming yu are able t find apprpriate academic envirnments, then yu shuld be smart abut chsing where t apply.Chse clleges and universities where yu can be mst cmpetitive based n yur skills and preparatin.Whether yu cmpete in the pl r n the stage r in the classrm, yu have the best chance f finding success when yur skills prve yur capacity t d the wrk and yu are cmpetitive with thse arund yu.Put yurself int cmpetitin at universities where yu fit best and enjy the success that is bund t cme yur way as a candidate.
