菊花的作文怎么写（英文版）菊花的生长过程
First, breeding methods
Story of Qiu general use of cutting propagation, in the 20 days prior to the colonization, southern areas to adopt more open field to increase sun, good drainage requirements matrix, and ventilation. Chrysanthemum cuttings take the point of requiring robust cuttings, pest-free, trim the second half of the law; 1/3-1/2 or remove the leaves, then cutting through the plug on the bed, inserted to a depth of the cuttings long 1 / 3 ; General chrysanthemum cuttings about 2 weeks to take root, root cuttings should be the increasing light and ventilation;
Second, the cultivation and management
1, soil conditions
Chrysanthemum like good drainage and fertile PH value of 6.5-7.2 soil, even for free. Shi mu into the compost maturity -5000 kg 4000 kg, 20 kg fertilizer. Ba Ping Shen Fan soil after planting Qikuan 0.6-0.8 m, 0.3-0.4 meters high.
2, colonization
After half a month to take root cuttings should be planted in a timely manner, from general to field planting cuttings 25-30 days; Zhu Xingju for the colonization of 20 cm × 15 cm. Large-flower can be sparse, floret type can be more dense.
3, Maya Topping
Chrysanthemum Huanmiao, should be carried out in a timely manner for the first time Topping, leaving 5-6 leaves. After Topping the first time, have a general 3 branches, as the cut-flower chrysanthemum cultivation can be carried out twice Topping, resulting in a 5-6 branches, most of the rest of the branches should be removed in a timely manner so as to avoid excessive consumption of plant nutrition.
Flower bud, after squaring, according to the need to be cultivated in a timely manner to all of the following side of the main Lei Lei removed in order to train a good quality of cut flowers; if the long train of cut chrysanthemum can be multi-lateral lei leave some;
4, lodging frame network
When the plants grow to about 30-40 cm, should be set up in a timely manner to mobile 1-2 layers of nylon net
Third, light-Ju as the production technology
Light is as chrysanthemum flowers for the regulation of effective measures, mainly for The Story of Qiu (Short-day conditions, the chrysanthemum flower), using light to extend the time to postpone the flower bud, and aimed to achieve control of flowering time.
Light control: The Story of Qiu colonization, the sunshine for less than 12 hours, began to extend the use of light at night time. Taiwanese general areas in a 100-watt incandescent chrysanthemum from the point of exposure to 1 m, 4-5 at home a Kalahari, 23:00 to 2:00 pm every day night light 3 hours, according to plant growth and a high degree of Cultivation time to market and the illumination of the date of the decision in a row, from the general cessation of light to the flowering time of 90-100 days.
Story of Qiu is a strong sensitivity to light plants, the continuity of light, the light intensity of the light time to determine whether the production of light-Ju as successful.
Fourth, pest and disease control
1, Infectious Diseases: There are chrysanthemum leaf spot, leaf spot and black spot, and so on, can be mancozeb, Tuobu Jin, carbendazim, and other prevention and treatment.
2, pests: aphids are, McGregor, Grub, should be on prevention and treatment in a timely manner to remove weeds and reduce the parasitic pests, spraying omethoate, dichlorvos, dicofol, and so on.
一、繁殖方法
秋菊一般采用扦插繁殖,在定植前的20天,闽南地区多采用露地加遮阳措施,基质要求排水良好、通气.插穗取菊花的生长点,要求插穗健壮、无病虫害,半叶修剪法；或去掉1/3-1/2的叶片,然后密密扦插于插床上,插的深度为插穗长的1/3；菊花一般扦插2周左右即可生根,生根后的插条应逐渐增加光照和通风；
二、栽培管理
1、土壤条件
菊花喜欢肥沃及排水良好PH值6.5-7.2土壤,忌连作.每亩施入腐熟堆肥4000公斤-5000公斤,复合肥20公斤.深翻土壤后耙平,种植畦宽0.6-0.8米,高0.3-0.4米.
2、定植
扦插生根后半个月应及时定植,一般从扦插到定植25-30天；定植的株行距为20厘米×15厘米.大花型可稀植,小花型可密些.
3、摘心抹芽
菊花缓苗后,应及时进行第一次摘心,只留下5-6片叶.经过第一次摘心后,一般产生3个分枝,做为切花栽培的菊花可进行两次摘心,产生5-6个分枝,其余分枝大多应及时去除,以免消耗过多的植株营养.
花芽分化、现蕾后,根据栽培需要应及时将主蕾以下所有侧蕾去除,以培养出品质良好的切花；如果培养多头切花菊可根据需要多留一些侧蕾；
4、架网抗倒伏
当植株长到30-40厘米左右时,应及时架设可移动式1-2层尼龙网
三、灯照菊的生产技术
灯照是对菊花进行花期调节的有效措施,主要是针对秋菊（短日照条件下开花的菊花）,采用延长光照时间促使推迟花芽分化,达到有目的控制开花时间.
光照控制的方法：当秋菊定植后,日照时间短于12小时,就开始采用夜间延长光照时间的方法.闽南地区一般采用100瓦白炽灯距离菊花生长点1米照射,每隔4-5米布置一盏,在夜间11点至凌晨2点时,每天夜里光照3个小时,根据植株生长高度和栽培上市时间而决定连续光照的日期,一般从停止光照到开花的时间为90-100天左右.
秋菊是光敏感性很强的植物,光照的连续性,光照的强度、光照的时间决定灯照菊生产是否能成功.
四、病虫害防治
1、侵染性病害：主要有菊花叶斑病、黑斑病和褐斑病等,可采用代森锰锌、托布津、多菌灵等防治.
2、虫害：主要有蚜虫、红蜘蛛、蛴螬,防治上应及时清除杂草,减少虫害的寄生,喷施氧化乐果、敌敌畏、三氯杀螨醇等.
