含水量为２５％的粉沙质壤土经６０Ｃｏ-γ射线２５０×１０４ｒａｄ辐照后种植辣椒，辣椒株高比对照增高２８．１６％，花蕾期地上部干重比对照增加９８．８８％，根干重增加１４５．００％，叶片叶绿素含量增加１８．９９％，光合强度提高５０．７３％。土壤的速效养分，水解氮比未辐照的提高２２．５０％，速效磷提高１７．８０％，速效钾提高１６．７６％，有效钢提高３．２１％，有效铁提高１．６４％。经辐照，土壤本身释放的氮、磷有效量至少相当于１ｈｍ２同时施（ＮＨ４）２ＳＯ４６７５ｋｇ和Ｃａ（Ｈ２ＰＯ４）２５６２．５ｋｇ的肥效。
In the sandy loam with 25% of water content, pepper was planted after irradiated by 60Co-γ ray at a dose of 250 × 104rad. The plant height of pepper increased 28.16% compared with the control, and the shoot dry weight increased 98.88% The dry weight increased 145.00%, leaf chlorophyll content increased 18.99% and photosynthetic intensity increased 50.73%. Soil available nutrients, hydrolyzed nitrogen increased by 22.50% than the unirradiated, available phosphorus increased 17.80%, available potassium increased 16.76%, effective steel increased 3.21%, effective iron increased 1.64%. After irradiation, the nitrogen and phosphorus released by the soil itself are at least equivalent to the effect of 1hm2 simultaneous application of (NH4) 2SO4675kg and Ca (H2PO4) 2562.5kg.
