在農(nóng)產(chǎn)品防護(hù)中,偽裝網(wǎng)與棚子的選擇需結(jié)合作物特性、生長環(huán)境及防護(hù)需求綜合判斷,二者各有適用場景,并無絕對優(yōu)劣之分。
In the protection of agricultural products, the selection of camouflage nets and sheds needs to be comprehensively judged based on crop characteristics, growth environment, and protection requirements. Both have their own applicable scenarios and there is no absolute superiority or inferiority.
偽裝網(wǎng)的優(yōu)勢在于靈活輕便與環(huán)境融合性。其材質(zhì)多為透氣的網(wǎng)狀結(jié)構(gòu),能有效調(diào)節(jié)光照強(qiáng)度,避免強(qiáng)光直射導(dǎo)致果實(shí)灼傷,尤其適合露天種植的漿果、蔬菜等作物。在防風(fēng)方面,偽裝網(wǎng)可通過適當(dāng)密度減緩風(fēng)速,減少葉片摩擦損傷,同時不阻礙自然降水滲透,保持土壤濕度平衡。此外,偽裝網(wǎng)安裝拆卸便捷,可根據(jù)季節(jié)變化靈活調(diào)整覆蓋范圍,冬季收起不影響作物接受自然光照,成本相對較低,適合短期防護(hù)或小面積種植場景。
The advantage of camouflage nets lies in their flexibility, lightness, and environmental compatibility. Its material is mostly a breathable mesh structure, which can effectively regulate the intensity of light and avoid direct sunlight causing fruit burns, especially suitable for crops such as berries and vegetables grown outdoors. In terms of wind prevention, camouflage nets can slow down wind speed and reduce blade friction damage through appropriate density, while not hindering natural precipitation infiltration and maintaining soil moisture balance. In addition, the camouflage net is easy to install and dismantle, and the coverage area can be flexibly adjusted according to seasonal changes. It does not affect the crops' natural light reception when folded in winter, and the cost is relatively low, suitable for short-term protection or small-scale planting scenarios.
搭建棚子則在全方位防護(hù)上更具優(yōu)勢。棚子多采用框架結(jié)構(gòu)搭配薄膜或板材,能形成封閉空間,有效抵御暴雨、冰雹等極端天氣對作物的沖擊,為幼苗培育、精細(xì)種植的作物提供穩(wěn)定環(huán)境。在溫度調(diào)控上,棚子可通過通風(fēng)口、遮陽簾等配件調(diào)節(jié)內(nèi)部溫濕度,適合對生長環(huán)境敏感的作物,如反季節(jié)蔬菜、花卉等。同時,棚子能阻擋鳥類、昆蟲等天敵侵?jǐn)_,減少病蟲害發(fā)生,降低農(nóng)藥使用量,不過其搭建成本較高,且固定結(jié)構(gòu)可能影響作物接受自然光照的均勻性,適合長期規(guī)?;N植。
Building a shed has more advantages in comprehensive protection. The shed mostly adopts frame structure with film or plate, which can form a closed space, effectively resist the impact of extreme weather such as rainstorm and hail on crops, and provide a stable environment for seedling cultivation and fine planting of crops. In terms of temperature regulation, the greenhouse can adjust the internal temperature and humidity through accessories such as ventilation openings and sunshades, which are suitable for crops that are sensitive to the growing environment, such as off-season vegetables, flowers, etc. At the same time, sheds can block the invasion of natural enemies such as birds and insects, reduce the occurrence of pests and diseases, and lower the use of pesticides. However, their construction cost is high, and the fixed structure may affect the uniformity of crops receiving natural light, making them suitable for long-term large-scale planting.
選擇時需關(guān)注作物生長階段:幼苗期抗逆性較弱,棚子的穩(wěn)定環(huán)境更利于存活;成株期需兼顧光照與通風(fēng),偽裝網(wǎng)的靈活性更具優(yōu)勢。從地域來看,多雨多風(fēng)地區(qū)可優(yōu)先考慮棚子的堅(jiān)固防護(hù),而光照強(qiáng)烈、氣候溫和地區(qū),偽裝網(wǎng)的透光透氣特性更能發(fā)揮作用。此外,還要結(jié)合種植周期與成本預(yù)算,短期臨時防護(hù)可選偽裝網(wǎng),長期固定種植則棚子的性價比更高。
When choosing, attention should be paid to the growth stage of crops: the resistance to stress is weak during the seedling stage, and a stable environment in the greenhouse is more conducive to survival; During the mature stage, it is necessary to consider both lighting and ventilation, and the flexibility of camouflage nets is more advantageous. From a regional perspective, in rainy and windy areas, the sturdy protection of sheds can be given priority, while in areas with strong sunlight and mild climate, the transparent and breathable characteristics of camouflage nets can play a better role. In addition, it is necessary to consider the planting cycle and cost budget. For short-term temporary protection, camouflage nets can be selected, while for long-term fixed planting, the cost-effectiveness of the greenhouse is higher.
無論是偽裝網(wǎng)還是棚子,核心都是為農(nóng)產(chǎn)品創(chuàng)造適宜的生長條件,需根據(jù)實(shí)際需求權(quán)衡二者的功能特點(diǎn),才能實(shí)現(xiàn)防護(hù)效果與種植效益的平衡。
Whether it is a camouflage net or a greenhouse, the core is to create suitable growth conditions for agricultural products. It is necessary to balance the functional characteristics of the two according to actual needs in order to achieve a balance between protective effects and planting benefits.
