总括上述,现将崔竹松对高产水稻主要生育阶段的长相要求及有关措施简述如下:1.苗期:培育壮苗,适期早插,是水稻增产的首要环节。明确插秧前壮苗的形态特征 为:根系发达,单株平均15—20个根,共中并夹有长1—2厘米的白根5—7条。茎基扁粗,叶挺,叶宽0.4—O.5厘米,叶色绿中带黄,苗高6寸左右,部分秧苗且已出现分蘖,插后发根力强,有利于早生快发等。措施上主要采用保温育苗,适当稀播,并加强苗床管理等。2.有效分蘖期:中心目的为促进有效分蘖及早发生。叶色上要求“上色快”,到7月5日左右有效分蘖停止期达到“一黑”。叶片要“甩开来”,累年平均单株宜1/3左右呈“三股叉’,状,一穴丛型呈“喇叭筒”状。在措施上,主要在细致整地,达到耕层深厚、肥沃、松软和平坦的基础上,采用双行式(4+7)×4寸插秧,一穴5—7苗,返青后浅灌一寸左右,早施和重施分蘖肥(称为前重),分蘖盛期看长相好坏酌情补肥一次(称为中补),并及时中耕、搔根和除草等。3.拔节到出穗期:中心目的为巩固有效分蘖,促进壮稈大穗。在长相要求上,叶色主要掌握“拔节黄”宜正常出现(浅绿到绿色),叶片表现“拉长叶”,孕穗中后期叶挺有弹性,呈“贴竿式”立起来生长(指13/0—15/0叶),茎稈粗壮,丛型如“大胡子”状(指一穴茎数多在15—20个)等。本期间在措施上,有?
To sum up, now Cui Zhusong on the high yielding rice main growth phase of the looks and requirements are summarized as follows: 1. Seedling stage: nurturing strong seedlings, suitable for early insertion, is the first key to rice yield. A clear planting seedlings before transplanting strong morphological characteristics are: developed root system, an average of 15-20 roots per plant, a total of 1-2 cm in length and white root folder 5-7. Stem-based flat rough, Ye Ting, leaf width 0.4-0.5 cm, yellow with green leaves, about 6 inches high seedlings, and some tillers have emerged seedlings, inserted after the strong hair root, is conducive to rapid hair growth and so early. The main measures taken by incubation nursery, appropriate sowing, and strengthen seedbed management. 2. Effective tillering stage: The central purpose is to promote effective tillering and early occurrence. Leaf color requirements “fast color”, to July 5 effective tillering stop period to achieve “a black.” Leaves to “throw off”, the average annual average of about 1/3 was “three forks,” shape, a plexus was “horn” shape in the measures, mainly in meticulous soil preparation, to reach deep plow On the basis of fertile, soft and flat, double-row (4 + 7) × 4-inch seedling transplanting is used. One hole of 5-7 seedlings is planted, ), Tillering stage to see the looks good or bad, if appropriate, make-up time (known as Zhong Bu), and timely cultivation, Sclerotinia and weeding, etc. 3. Jointing to heading: the central purpose to consolidate effective tillering, In appearance, leaf color mainly holds “jointing yellow”, which should appear normally (light green to green), leaf “stretch leaf”, leaf bouncing late in booting period, 13 / 0-15 / 0 leaves), stalks sturdy, Cong type, such as “bearded” shape (referring to a hole in the stem of more than 15-20), etc. During this period in the measures?
