中共余姚县委丰产畈,1960年試种了1.2亩春馬鈴薯——早稻——秋馬鈴薯一年三熟丰产田,春馬鈴薯平均亩产5,261斤,折合原粮1,315.2斤;早稻平均亩产673.7斤;秋馬鈴薯平均亩产2,062斤,折原粮515.4斤;全年三熟获得了平均亩产粮食2,579.1斤的高額丰产。全年的丰产經驗是: (一)早熟为綱,五早并举:为达到“多种、高产、多收”的目的,采取了以早为綱,推行“早播、早种、早发、早熟、早收”五早并举的措施。春馬鈴薯选用了早熟的紅皮腰子种,立春播种,此一股大田提早10～15天;早稻为秈稻陆財号,4月26日播种,5月25日移栽;秋馬鈴薯于8月18日下种。春薯早播,可延長其生長明,增加光合产物的累积;井能使块茎在成長过程中,有較長的時間处在16～18℃的适宜薯块膨大的溫度下以加速生長,因而結薯多而大。早稻移植期虽較綠肥田及早熟春花田
Yuyao County, the Communist Party of China Feng Shui, 1960 planted 1.2 acres of spring potato - early rice - autumn potato three crops a year, the average yield of spring potato 5,261 pounds, equivalent to 1,315.2 pounds of raw grain; early rice average yield 673.7 kg; autumn The average yield of potato is 2,062 jin and the original raw grain is 515.4 jin. The average yield of 2,579.1 jin per mu was double-cropped in the whole year. The rich experience of the whole year is as follows: (I) Precocity as the key link and concurrently as early as the fifth: In order to achieve the objectives of “variety, high yield and income”, the policy of taking “early sowing, early seedling, Premature, early harvest ”five early measures. Spring potato selection of red kidney seed, spring planting, this field early 10 to 15 days; early rice Indica rice land, sown on April 26, May 25 transplanting; autumn potato in August 18 Day species. Early sowing of spring potato can prolong its growth and increase the accumulation of photosynthetic products. Well can make tubers grow faster, and have a longer time at 16 ~ 18 ℃ suitable temperature to expand the body to accelerate growth, and thus Tuber more and big. Although the early rice transplanting period than the green field and early spring Chunhua
