大棚极速飞艇计划掩蔽粉饰掩盖作育的7大关键
Seven Key Points for Covering and Cultivating Insect-proof Net in Greenhouse
大棚极速飞艇计划的掩蔽粉饰掩盖作育已成为当代农业展开的一个标志,不过很多作育户似乎是污蔑的掩蔽粉饰掩盖作育四个字的含义,他们重复是掩蔽粉饰掩盖上极速飞艇计划就不论了,这是一种很告急的错误。极速飞艇计划厂家在这里照顾极速飞艇计划,所谓的掩蔽粉饰掩盖作育,就是先掩蔽粉饰掩盖,后作育,两者缺一不可,而敷衍作育二字,很多作育户就无视了。
The cultivation of pest-proof net in greenhouse has become a symbol of modern agriculture, but many cultivators seem to distort the meaning of four words of cultivation. They often ignore the cultivation of pest-proof net, which is a very serious mistake. Insect-proof net manufacturers here inform us that the so-called cover-up training is to cover up first and then cultivate, both of which are indispensable. For the word "cultivation", many cultivators ignore it.
大棚极速飞艇计划的掩蔽粉饰掩盖作育时间,紧张在夏秋高温时节,应选用抗热、耐湿、抗病种类。种类选用妥当,掩蔽粉饰掩盖作育后,较露地作育的经济效益、社会效益十分明白。如伏毛菜、伏萝卜、伏豇豆、早秋花椰菜、早秋甘蓝、早秋大白菜、春季西红柿、秋辣椒以及秋菜和茄果蔬菜早熟作育育苗。
The cultivation time of pest-proof net in greenhouse is mainly in summer and autumn high temperature season. The heat-resistant, humidity-resistant and disease-resistant varieties should be selected. The economic and social benefits of cultivation in the open field are more remarkable than those of cultivation in the open field. Such as Fucai, Furadi, Fucowpea, early autumn broccoli, early autumn cabbage, early autumn cabbage, autumn tomatoes, autumn pepper, autumn vegetables and eggplant early maturity cultivation seedling.
2.挑选妥当范例
2. choose suitable standards.
依据菜地的外形和差异作物、时节的需要来挑选极速飞艇计划,范例紧张包括幅宽、孔径、丝径、颜色等。范例因此目数多少而定,目数即密度范例,即在25.4mm×25.4mm内经纱与纬纱的根数,如25.4mm×25.4mm内,经、纬纱各为20根,即为20目,应依据防治益虫虫体的大小选用妥当的网目。一样伟大蚜虫的体长2.3~2.6mm,体宽1.1~1.5mm;小菜蛾成虫体长6~7mm,展翅可达12~15mm,故斲丧上多选用17~25目极速飞艇计划。5~10月夏秋时节蔬菜、花草作育上多用17~22目白色极速飞艇计划。丝径0.18~0.22mm,幅宽1.2~3.6m。颜色有白色、银灰色和玄色三种。如需增强蔬菜大棚极速飞艇计划的遮光结果,可选用玄色极速飞艇计划。银灰色极速飞艇计划的避蚜结果更好。白色极速飞艇计划透光率较银灰色的好,但夏季棚内温度略高于露地,适用于大少数喜光的蔬菜作育。
Insect-proof nets are selected according to the condition of vegetable fields and the needs of different crops and seasons. The standards mainly include width, aperture, silk diameter, color and so on. The standard is determined by the number of meshes. The number of meshes is the density standard. That is, the number of warp and weft yarns in 25.4mm * 25.4mm, such as 25.4mm * 25.4mm, and the number of warp and weft yarns in 20 meshes, respectively. The appropriate meshes should be selected according to the size of pest control bodies. Generally, aphids are 2.3-2.6 mm in length and 1.1-1.5 mm in width, while adults of Plutella xylostella are 6-7 mm in length and 12-15 mm in wings. Therefore, 17-25 mesh insect control nets are often used in production. During the summer and Autumn period from May to October, 17-22 meshes of white insect-proof net were often used in the cultivation of vegetables and flowers. The wire diameter is 0.18-0.22 mm and the width is 1.2-3.6 M. The colours are white, silver-gray and black. If you need to strengthen the shading effect of insect-proof net in vegetable greenhouse, you can choose black insect-proof net. Silver-grey insect-control net has better Aphid-avoiding effect. The transparency of the white insect-proof net is better than that of the silver-gray one, but the temperature in the shed is slightly higher than that in the open field in summer, so it is suitable for the cultivation of most light-loving vegetables.

3.选用妥当掩蔽粉饰掩盖要领
3. Choose the appropriate cover-up method
全网掩蔽粉饰掩盖和网膜掩蔽粉饰掩盖均有避虫、防病、增产等结果,但对种种十分气候顺应技艺差异,应机动运用,在高温、少雨、多风或强台风频发的夏秋日,应选用全网掩蔽粉饰掩盖作育,在梅雨时节,或延续阴雨气候可选用网膜掩蔽粉饰掩盖作育。
The whole net cover and omentum cover have the effect of insect avoidance, disease prevention and yield increase, but they have different adaptability to various abnormal climates. They should be used flexibly. In summer and autumn when high temperature, little rain, windy or strong typhoon occur frequently, the whole net cover culture should be selected. In rainy season, or continuous rainy climate, the omentum cover culture can be used.
4.棚高妥当
4. shed high suitable
小拱棚或水平棚掩蔽粉饰掩盖时,棚高宜高于作物,抑制菜叶贴紧大棚极速飞艇计划,被网外跳头号益虫取食或产卵于菜叶,若在高温时期举行蔬菜掩蔽粉饰掩盖作育则棚内空间越大越好,因此,以棚高2m的大平棚掩蔽粉饰掩盖作育为宜,即可儿工应用,又利于蔬菜生长。
When covered by a small arch shed or a horizontal shed, the height of the shed should be higher than that of the crops, so as to avoid the vegetable leaves sticking to the shelter insect-proof net and being fed or laid eggs by pests such as beetle jumping out of the net. If covered by vegetables during high temperature, the larger the space in the shed is, the better. Therefore, it is appropriate to cover and cultivate the vegetable in a flat shed with a height of 2 m, which can be operated manually, and is also beneficial to vegetable leaves. Vegetables grow.
5.全期掩蔽粉饰掩盖
5. full term cover up
极速飞艇计划遮光,但又遮光未几,不会对蔬菜作物构成光照缺乏的影响,不需日盖夜揭或前盖后揭,应全程掩蔽粉饰掩盖,先覆网后耕耘。两边用砖或土压严实,不给益虫陵犯时机,才气抵达餍足的防虫结果。一样伟微风力外形下可不消压网线。如遇5~6级和风,需拉上压网线,以防范和风将蔬菜大棚极速飞艇计划翻开。
Insect-proof net shading, but not much shading, will not affect the lack of light on vegetable crops, do not need to cover up day and night or before and after uncovering, should cover up the whole process, first cover the net and then cultivate. Only when both sides are compacted with bricks or earth, and no time for pest invasion is given, can the satisfactory pest control effect be achieved. It is not necessary to press wire under general wind conditions. In case of gale of grade 5 to 6, it is necessary to pull up the wire to prevent gale from lifting the insect-proof net of vegetable greenhouse.
6.泥土消毒
6. soil disinfection
掩蔽粉饰掩盖前一定要举行泥土消毒,杀逝世泥土中的病菌和益虫,堵截虫源。
Before covering up, soil disinfection must be carried out to kill bacteria and pests in the soil and to block the source of insects.
7.增强田间料理
7., strengthen field management.
要施足基肥,增长追肥次数,一样伟大叶类菜生育期短,不需追肥。白色大棚极速飞艇计划在气温较高时,网内气温、地温较网外高1℃左右,给蔬菜斲丧带来一定影响,故在7~8月份气温格外高时,可增长洒水次数,对峙网内湿度,洒水上肥以朝晨或黄昏为宜,可选用网外泼浇,或沟灌,有条件的本地好选用微型滴灌和喷灌。尽管纵然增参与网应用次数,出入网时要及时拉网盖棚,不给益虫陵犯时机。要通常巡视田间,及时去除挂在网上或田间的益虫卵块。查抄网、膜有否粉碎,加以及时修补。
To apply sufficient base fertilizer and reduce the number of topdressing, the growth period of leaf vegetables is generally short, and no topdressing is needed. When the temperature of insect-proof net in white greenhouse is higher, the temperature inside the net and the ground temperature are about 1 C higher than that outside the net, which has certain influence on vegetable production. Therefore, when the temperature is especially high in July-August, the number of sprinklers can be increased, the humidity in the net can be maintained. It is appropriate to sprinkle fertilizer in the early morning or dusk. Sprinkler outside the net or furrow irrigation can be used, if conditions are appropriate. Mini-drip irrigation and sprinkler irrigation are the best choice for land use. As far as possible to reduce the number of operations into the network, in and out of the network to pull the net in time to cover the shed, do not give pests the opportunity to invade. Often patrol the fields and remove pest eggs hanging on the Internet or in the fields in time. Check whether the net and membrane are damaged and repair them in time.
