Flax cultivation techniques autumn


. Chuxiong agricultural school Chuxiong 675 ~; 2. Xu Yingzhen Nanhua County Forestry Station, Yunnan, South China 6752 ~) With the development of commodity economy and people's diet structure adjustment is used, people's consumption concept is undergoing great changes, more and more people began to have relied Duohuang give attention to hunger in the mountains of vegetables. The result of natural selection due to the long, wild vegetables, strong vitality,[link widoczny dla zalogowanych], robust growth, with little or no pests, do not use pesticides and fertilizers; both wild vegetables with a unique flavor, taste delicious, nutritious, physical fitness and other effects, times favored by consumers. In order to meet consumer demand, here are several techniques of forest and cultivation of vegetables for the peer reference. Nitrogen, which should be fast growing period of the dressing before the end of the bud. Flax root growth is weak, so the lack of prime plots on the shape of the fir and the rapid growth period of the spraying of 0.2% to 0.3% zinc, boron, copper, molybdenum and other composite fertilizer solution once, can play to yield better results. 6 after sowing flax strengthen management, to promptly pay close attention to fertilizer and water management, disease, insects, grass and rodent control as the main content Integrated field management for the linen high-yield, high quality, efficient and create favorable conditions. (1) Growing flax fertilizer and water management to ask, to be consumed to produce a dry water 4o0 ~ 300kg. Flax growing season coupled with positive winter and autumn drought season, therefore, soil moisture and linen according to growth condition, within 2 days after seeding, fir-shaped stage, fast growth period, flowering and maturity appropriate supplemented by artificial irrigation, Tian asked to keep the soil water holding capacity of 65% to 75% is appropriate. Maple-shaped at the time of fertilization and rapid growth period, requiring the combination of fertilization and irrigation to increase fertilizer efficiency, and promote the growth of flax. (2) pest control pest of flax are against the whole growth period, we must adhere to the In the selection of resistant varieties, rotating their crops,[link widoczny dla zalogowanych], fertilizer and water management strengthening, based on the types of pests and diseases in time for chemical control, to facilitate the robust growth of hemp seedlings and reduce losses. Main diseases are: flax anthracnose, powdery mildew, blight, leaf blight, rust, etc., should be targeted in the early stages, anthrax used fu the United States, lucky star, triadimefon, carbendazim, mancozeb, metalaxyl MZ joint chemicals such as continuous control. Major pests are black cutworm, beet armyworm, Spodoptera litura, cabbage moth, silver 1 Aralia de wood (Am on the pumping port cJtIP mad cowpea n) Aralia German dish of wood, also known as a tree, stabbed the old package, thorn cabbage, five hydrants, is a five Jiake De Wood is a perennial deciduous shrub or small tree. 1.1 The distribution is mainly distributed in central and south Yunnan, Kunming, Chuxiong, Baoshan, Dehong, Xishuangbanna, Red River, Simao, Lincang, Lijiang, mid and so on. To shoot package for food. Widely distributed in the southwestern Yunnan at an altitude of 1500 ~ 3000m mountain stream side Qing, moist shady forest,[link widoczny dla zalogowanych], mostly wild. ! Zhu !:::::==:::::! agnata, can use pyrethroid or organophosphate insecticide spray in the prevention and treatment of young can also be used furan Dan, methyl 16o5 spread toxic soil and other agents for prevention and treatment. (3) grass, rat control methods are manual weeding weeding martensite and Chemical Control in two. Small plots of weeds can be manual weeding; such as low-lying, high water table, grass terraces can harm serious weed species, select the appropriate herbicide, such as acetochlor, Quizalofop, Gallant could, get the net catch, fine stability killing, MCPA, green yellow, etc. Long time Control in. After flowering, rodent serious plots, the choice of bromadiolone, sodium and other pharmaceutical preparation of the enemy mouse baits for control. 7 timely harvest fiber flax harvest time on yield and fiber quality has a greater impact. Linen can be divided into green mature maturity, ripening period and ripening period. The color of flax stems and leaves, and capsule is to determine the degree of fitness of an important basis for harvest. If the green mature stage to harvest, the stem water content, easy storage, a linen low fiber tension difference; as in the ripe stage before harvest, the more water loss flax stems, a high degree of fiber lignification and become stiff fragile, fiber number reduced number of 1.5 ~ 2.0; when in ripening period,[link widoczny dla zalogowanych], the whole field of 1 / 3 of the capsule was brown, 1 / 3 of the hemp stem pale yellow, the lower part of flax stems 1 / 3 leaves fall off, which amounts to process maturity,[link widoczny dla zalogowanych], is the best time to harvest, of which all fields are 1 / 3 of the capsule was brown are the main features. It should be noted grab sunny morning dew in the morning after the disappearance of harvest time, so that classification pull Ma, net pick weeds, throw net root soil, the root section of the edges, grading Binding, the diameter of 7 ~ 10cm, with wool and linen for around, tied at the top of 6 ~ 7cm at the roots, drying in the field to 8 to 9 into the dry, after the selling of threshing time. Note that anti-rain, mildew heart, anti-fire. Pi li ah �� 1 a 1r
