肥料是丰产的前提,沒有充足的肥料,就难以达到增产的目的。随着人民生活的提高,各地蔬菜栽培面积不断扩大,而肥料用量普遍不足;在增施肥料的基础上,更应該注意經济用肥,因此如何合理施肥,是目前蔬菜栽培中值得研究的一个重要問題。自从1958年我国农业生产大跃进以來,西安市出現了不少番茄丰产田,亩产高达3万至4万斤,超过一般产量数倍。1959年我所以东郊红光人民公社草滩队为重点,对番茄的施肥技术进行了調查,初步总結出以下几点: 一、施肥量:番茄的产量在很大程度上决定于施肥量;在一定范围內,产量大体上随着施肥量的增加而提高。如表1指出,根据所施肥料含有成份的推算,亩产番茄8千斤至1万斤者,施纯氮约30斤;亩主增高至1万5千斤至2万斤时,施氮量约100斤;在亩产达3万 Fertilizer is the premise of high yield, without adequate fertilizer, it is difficult to achieve the purpose of increasing production. With the improvement of people’s life, the area of ​​vegetable cultivation continues to expand, while the amount of fertilizer is generally inadequate. On the basis of increasing fertilizers, more attention should be paid to economic use of fertilizers. Therefore, it is worth studying a lot in vegetable cultivation important question. Since the Great Leap Forward in China’s agricultural production in 1958, many tomato rich-cropped fields have emerged in Xi’an, with output ranging from 30,000 to 40,000 kg per mu, more than several times the normal output. In 1959, I focused on the grass beach team of Honggou People’s commune in the eastern suburb and conducted a survey on fertilization techniques of tomato. The results were summarized as follows: First, the amount of fertilizer: To a large extent, the yield of tomato is determined by the amount of fertilizer applied. Within a certain range, the yield generally increases with the amount of fertilizer applied. As shown in Table 1, according to the calculation of the components contained in the fertilizers, about 8 kg to 1 kg of mu produce tomatoes and about 30 kg of pure nitrogen. When the main amount of mu increased from 15 kg to 2 kg, 100 pounds; up to 30,000 mu
