网址:https://www.shengjiewangye.com    发布时间:2020-04-28
(1)全期包括
(1) The whole period includes
网挡住了光线。然而遮光不多,不需要白日盖和晚上揭,应该包括整个过程。两边用砖或土密封。只有没有害虫侵略的机会,才干到达令人满意的作用。在正常的风力条件下,可压网线。在5-6级劲风的情况下,拉动网线,防止强风抬升网络。
The net blocked out the light. However, there is not much shading, and it does not need to be covered in the daytime or at night, which should include the whole process. Both sides are sealed with brick or earth. Only when there is no chance of pest invasion can we achieve a satisfactory effect. Under normal wind conditions, the network cable can be pressed. In case of strong wind of level 5-6, pull the network cable to prevent strong wind from lifting the network.
(2)挑选合适的标准
(2) Choose the right standard
大棚防虫网的标准主要包括宽度、孔径、颜色等。特别是,网的孔径和数量太小,而网眼尺寸太大,不能到达期望的抗虫作用。网格数量太大,网格太小,尽管能够防虫,但通风不良,导致温度高,遮荫过多,不利于作物生长。
The standard of insect control net in greenhouse mainly includes width, aperture, color, etc. In particular, the aperture and number of mesh are too small, and the mesh size is too large to achieve the desired insect resistance. The number of grid is too large and the grid is too small. Although it can prevent insects, the ventilation is not good, resulting in high temperature and too much shade, which is not conducive to crop growth.
除了网掩盖外,结合病虫害抗性改良品种、耐热改良品种、无公害有机肥、生物农药、无公害水源、微喷微灌等归纳配套措施,能够获得更好的作用。
In addition to net covering, combined with improved varieties of disease and pest resistance, heat-resistant improved varieties, pollution-free organic fertilizer, biopesticide, pollution-free water source, micro spray micro irrigation and other supporting measures, we can get better effect.
(3)正确运用和保管
(3) Proper use and safekeeping
网在田间运用后,应及时收集、清洗、烘干、卷制,以延伸其运用寿命,提高其经济效益。
After the net is used in the field, it should be collected, cleaned, dried and rolled in time to extend its service life and improve its economic benefits.
(4)一般情况下,应选用22-24目网。与春秋季和夏日相比,气温较低,光照较弱,因此应选用白色。夏日,应挑选黑色或银灰色的进行遮光和降温。在蚜虫和病毒性疾病严重的地区,应挑选银灰色的,以避免蚜虫和防备病毒性疾病。
(4) In general, 22-24 mesh network shall be selected. Compared with spring, autumn and summer, the temperature is lower and the light is weaker, so white should be selected. In summer, black or silver gray should be selected for shading and cooling. In areas with serious aphids and viral diseases, silver gray ones should be selected to avoid aphids and prevent viral diseases.

(5)确保掩盖质量,大棚防虫网要全封闭掩盖。四周用土压封严,并将压膜线固定牢固;进出大中型工棚和温室的门须安装网,进出时应留意立即关闭。
(5) To ensure the quality of cover, the insect net in the shed should be completely closed. All sides shall be sealed with earth pressure, and the film pressing line shall be fixed firmly; the doors of large and medium-sized construction sheds and greenhouses shall be installed with nets, and the doors shall be closed immediately when entering and leaving.
(6)小拱棚上掩盖网,棚的高度显着高于农作物,以防止农作物的叶子粘在防虫网上,防止害虫从网外吃蔬菜叶子或在蔬菜叶子上产卵。用于封闭出风口的防虫网与通明罩之间不该有缝隙,避免给害虫留下通道。随时查看并修补昆虫网上的洞和缝隙。
(6) The height of the shed is significantly higher than that of the crops, so as to prevent the leaves of the crops from sticking to the insect prevention net, and prevent the pests from eating the vegetable leaves outside the net or laying eggs on the vegetable leaves. There should be no gap between the insect screen used to close the air outlet and the open cover to avoid leaving a passage for pests. Check and repair holes and gaps in insect webs at any time.
(7)害虫操控。种子、土壤、塑料大棚或温室框架、框架材料等,很可能带着害虫和卵。种植农作物前,要将其间带着的害虫消除。
(7) Pest control. Seeds, soil, plastic shed or greenhouse frame, frame materials, etc., are likely to carry pests and eggs. Before planting crops, eliminate the pests in them.
(8)挑选适合室内种植的品种。在种植过程中,应留意行距和株距,适当间伐。
(8) Select varieties suitable for indoor planting. In the process of planting, pay attention to row spacing and plant spacing, and thinning properly.
(9)土壤应深耕。施用的基肥量,如腐熟的农家肥和复合肥应满足。在作物生长发育期间,应及时施用叶面肥。
(9) The soil should be ploughed deeply. The amount of base fertilizer applied, such as mature farmyard fertilizer and compound fertilizer, should be satisfied. During the growth and development of crops, foliar fertilizer should be applied in time.
(10)在田间管理时,应留意网室的温度和湿度,浇水后应及时通风,避免因温度和湿度过高而引起疾病。
(10) In the field management, pay attention to the temperature and humidity of the net room, and timely ventilate after watering to avoid diseases caused by high temperature and humidity.
