“肥是劲”、“有收无收在于水,收多收少在于肥”,这些农谚充分说明“肥”在农业“八字宪法”中的重要地位,以及施肥对增产的重大意义。一九五八年以来,羣众创造了无数高产事例,试验研究机构也大搞丰产田和施肥研究,施肥技术有了很大的提高,创造了丰富的施肥经验,并初步明确了施肥技术与棉株生物学特性和营养特点的关系,为进一步探明棉花施肥的实质提供了线索。
“The fat is strong”, “the income is collected and the income is increased and the income is reduced.” These agricultural proverbs fully demonstrate the important position of “fat” in the “eight-character constitution” of agriculture and the great significance of fertilization in increasing output. Since 1958, the masses have created numerous high-yielding examples. Experimental research institutes have also engaged in the study of fertilization and fertilization. The fertilization technology has been greatly improved and abundant fertilization experience has been created. The preliminary application of fertilization technology and The relationship between the biological characteristics and nutritional characteristics of cotton plants provided clues for further ascertaining the essence of cotton fertilization.
