  requirement of fertilizer
    According to the nutrient absorption rule of the tumour stem mustard, the requirement of fertilizer was studied. The results showed that if the goal output of hybrid tumore stem mustard is 3 500 kg/667 m2, pure nitrogen demanded is 33.56 kg, the phosphorus (P2O5) is 7.63 kg, the potassium (K2O) is 25.47 kg, its proportion is 1∶0.23∶0.76.

This article was a summary on the chemical fertilizer divisions of Jiangxi province which was based on fertilizer sourcer, distribution of soil nutrient content, the requirement for fertilizer of main crops in defferent soils and the efficiency of chemical fertilizer in variaus areas of the province. Acording to the chemical fertilizers being used at present, its requirement and characters in many regions, so we named divisions and subdivisions based on principles and provincial agricultural division. Jiangxi was divided into eight primary regions and twelve secondary regions in order to meet the chemical fertilizers needed in the year of 1990 and the requirements of chemical fertilizers in the year of 2000 in whole province.

Cultivation with film-mulching increased fertilizer supply ability of soils and promoted nutrient absorption by sweet pepper plants.During the whole process of growth and development of sweet pepper,the nutrient contents in the soil were higher at early stage and decreased gradually,having a negative correlation to the intensity of nutrient absorption by plants.Under the conditions of film-mulching,the pepper plants demanded a little of nutrients,the peak of nutrient absorption appeared at the beginning to full harvest stages during which the supply and demand of nutrients fell into a sharp contradiction.The sweet pepper plants film-mulched must receive more organic manure,work commercial fertilizers of phosphorus and potassium mixtured with semi-decomposed organic manure into full layers before transplanting,topdress relative more fertilizer of nitrogen at stages both of fruiting and harvesting,all these will help to increase yield of sweet pepper.

地膜覆盖栽培提高了土壤的供肥能力,促进了甜椒对养分的吸收。在甜椒整个生育过程中,土壤养分含量前期较高,以后逐减,与植株养分吸收强度成负相关。覆膜甜椒前期需肥较少,吸肥高峰出现在采收至采收盛期,此间养分供需存在尖锐矛盾。对覆膜甜椒增施半腐熟有机肥,磷、钾化肥与有机肥混合栽前全层施入,结果至采收期分次适当多追氮素化肥,将有助子产量的提高。
