一、主要技术指标: 1.产量结构指标:亩产500—550公斤的产量结构为,亩穗数26—27万,每穗80—85粒,千粒重25—26克。 2.分蘖动态指标:插秧后5—7天开始分蘖。有效分蘖期分蘖迅速,平均亩日增蘖1万左右,7月15日前分蘖数达到穗数。最高亩茎数45万左右。 3.叶色变化:从分蘖到孕穗期保持青绿色,抽穗前稍转淡变黄。开花后半月,保持3—4片绿叶,黄熟时1—2片绿叶,远视绿中带黄。二、主要栽培措施: 1.早插秧。收麦后及早整地,浅耕灭茬,亩施厩肥1000公斤、磷肥30公斤。插秧前每亩用0.25公斤杀草丹兑水40倍,浅水喷洒,借水把药充分散开。插秧应及早进行,最晚不得晚于6月30日。行距6寸,株距4寸,每亩2.5万穴,每穴6—8株。注
First, the main technical indicators: 1. Yield structure indicators: Yield 500-550 kg per mu yield structure, acre 26-26 million acres, 80-85 grains per spike, grain weight 25-26 grams. 2. Tiller dynamic indicators: Transplanting 5-7 days after tillering. Effective tillering tiller quickly, the average mu tillering about 10,000, July 15 tiller number to reach the number of spikes. The maximum number of mu 450,000 or so. Leaf color changes: from the tillering to booting to maintain the turquoise, turn pale yellow slightly before heading. Half a month after flowering, 3-4 leaves to keep green leaves, 1-2 green leaves when the yellow leaves, hyperopia green with yellow. Second, the main cultivation measures: 1. Early planting seedlings. After the wheat harvest, the soil will be planted as soon as possible, shallow tillage and stubble planting shall be carried out. 1,000 kg of livestock manure shall be used per mu and 30 kg of phosphate fertilizer. Prior to transplanting 0.25 kg of acacia Dan dilute water 40 times, spraying shallow water, the water to fully spread the drug. Transplanting should be carried out as soon as possible, no later than June 30 at the latest. 6-inch spacing, spacing 4-inch, 25,000 acre per acre, 6-8 per hole. Note
