Description
技术领域：Technical field:
本实用新型涉及农作物的地膜覆盖技术领域，尤其涉及一种作物单株立体覆盖膜。The utility model relates to the technical field of plastic film covering of crops, in particular to a three-dimensional covering film for a single crop.
背景技术：Background technique:
随着地膜覆盖技术的广泛应用，人们发现作物地膜覆盖栽培在给农业生产创造诸多益处之外，也给作物生产过程带来许多难以克服的矛盾。首先，往复一年的重复地膜覆盖栽培会造成农田地膜残留污染，形成农田逐步积累严重的“白色污染”问题；二是地膜覆盖栽培在提高地温的同时，造成土壤养分的过度消耗，尤其土壤有机质的过度消耗和土壤微生物区系的紊乱，给土壤肥力的持续供应和土壤生产力的持续发展造成潜在压力，连年覆盖栽培使土壤呈贫瘠趋势；三是地表温度过度升高造成作物根系生长的浅层分布，给作物生长发育造成根系发育不良，营养吸收范围浅层化，严重影响作物品质的提高；四是在前期湿度过大和土壤粘重的地区，地膜覆盖操作困难，机械化覆膜难以实现，覆膜需要集中耗费大量的劳动投入，往往出现移栽(或播种)不能及时覆盖，造成田间短时间(一天或几天)的低温环境，引导前期低温敏感作物生殖生长阶段提前，出现早花现象普遍发生(如烟草)，使得地膜覆盖的质量和效果难以保证；五是地膜覆盖对移栽幼苗的覆盖时间较短，以烟草等高大作物为例，膜上移栽(先覆膜后开口移栽)的保护时间较短，且不能达到整株保护效果；膜下移栽(先移栽后覆膜)需要深挖穴移栽，在膜下的生长时间同样较短，而且开膜放苗往往造成幼苗太阳灼伤，形成较长时间的二次缓苗期，遇到偶然的低温天气，也会出现二次低温冷害，对提高产量和改进品质造成较大限制。传统的地膜覆盖技术，即在农田起垄后，在垄上用机械或人力覆盖地膜，地膜两端用土块压实。这种使用方式要么先在垄上移植幼苗，然后在幼苗上覆盖地膜；要么先在垄上覆盖地膜，然后地膜上抠孔，在将幼苗移植其孔内。前种方式覆膜时容易压苗，导致苗杆弯曲甚至折断，进而死亡，造成植株间隙空缺。后一种方式将地膜抠开，保温效果不好，不利于作物成长。而且，这种覆膜方式往往地膜覆盖一条垄或者一片区域，一旦某一植株染病，病害不易控制。With the wide application of plastic film mulching technology, it is found that crop film mulching cultivation not only brings many benefits to agricultural production, but also brings many insurmountable contradictions to the crop production process. First of all, repeated plastic film mulching cultivation for one year will cause residual pollution of farmland plastic film, forming a serious problem of "white pollution" gradually accumulated in farmland; second, plastic film mulching cultivation will cause excessive consumption of soil nutrients, especially soil organic matter, while increasing ground temperature The excessive consumption of the soil and the disorder of the soil microflora have caused potential pressure on the continuous supply of soil fertility and the sustainable development of soil productivity, and the soil has become barren after successive years of mulching cultivation; the third is the shallow layer of crop root growth caused by excessive surface temperature The distribution of crops causes poor root development and shallow nutrient absorption range, which seriously affects the improvement of crop quality; fourth, in areas with excessive humidity and heavy soil in the early stage, it is difficult to operate plastic film mulching, and it is difficult to realize mechanized mulching. Membranes need to intensively consume a large amount of labor input, and often the transplanting (or sowing) cannot be covered in time, resulting in a short-term (one or several days) low temperature environment in the field, leading to an early stage of reproductive growth of low temperature sensitive crops, and early flowering is common (such as tobacco), which makes it difficult to guarantee the quality and effect of plastic film covering; fifth, the covering time of transplanted seedlings by plastic film covering is relatively short. Take tall crops such as tobacco as an example, transplanting on the film (first cover the film and then open the mouth to transplant) ) protection time is short, and can not achieve the protection effect of the whole plant; transplanting under the film (transplant first and then cover the film) needs to dig deep holes for transplanting, and the growth time under the film is also short, and it is often difficult to release the seedlings after opening the film. The sun burns the seedlings and forms a longer secondary seedling slowing period. When encountering occasional low temperature weather, secondary low temperature chilling damage will also occur, which will greatly limit the increase in yield and quality. The traditional plastic film mulching technology is to cover the ridges with mechanical or manpower after the ridges are raised, and the two ends of the mulch are compacted with soil blocks. This method of use either first transplants seedlings on the ridge, and then covers the seedlings with plastic film; or first covers the ridge with plastic film, then cuts holes on the plastic film, and transplants the seedlings into the holes. In the former way, it is easy to press the seedlings when mulching, which will cause the seedling stems to bend or even break, and then die, resulting in a gap in the plant. The latter method opens the mulch film, which has poor heat preservation effect and is not conducive to crop growth. Moreover, this method of mulching often covers a ridge or an area with plastic film. Once a certain plant is infected, the disease is not easy to control.
为解决上述技术问题，出现了针对单株作物的立体覆膜技术，如中国专利申请号：201220273863.2公开了一种大田作物单株立体覆膜用具，具体结构如图3所示，其主要包括采用金属或塑料制作的框架6和塑料膜，其中，框架上进一步套接有框罩7(起压膜作用，也称为压膜套圈)，框架上部设置有上底，框架下部设置有下底，上底和下底之间设置有3-4根支撑柱，支撑柱与上底，下底之间固定连接；塑料膜包覆在框架上，框罩覆盖在塑料膜和框架的外部。这种技术中使用普通塑料膜，将塑料膜裁切呈固定形状后，包覆在框架结构外部，再用框罩7套接压实，(框罩即压膜套圈)。操作起来复杂且麻烦，效率低，而且，操作过程中易造成塑料膜破损。In order to solve the above-mentioned technical problems, there has been a three-dimensional film-covering technology for single crops. For example, Chinese patent application number: 201220273863.2 discloses a three-dimensional film-covering tool for single-plant field crops.

The technical key of the three-dimensional film covering, the utility model is used together with the three-dimensional film covering appliance. Multiple utility models are connected into one by tearing the thread and then wound on the reel or rolled into a roll by itself. When in use, one of the bag-shaped The film is torn off along the tear line and unfolded. After unfolding, the bag-shaped film is placed on the frame of the three-dimensional laminating tool. The bag-shaped film is tightly placed on the three-dimensional laminating tool. The bottom is slightly tight, and the radius of the bottom is reserved. The length is so that the film is pressed with soil, so that the utility model is fixed on the whole frame, and reaches the purpose of tightness, compaction, and formation of airtight single plant heat preservation. The utility model covers a single plant, and the crops are separated from each other, and the covering is convenient, and the purpose of covering while transplanting is realized; the covering time is saved and the labor intensity is reduced; the long-term field heat preservation and moisturizing effect can be realized; the field covering operation efficiency is improved; The natural environment of the field soil avoids the excessive consumption of soil nutrients caused by general plastic film mulching, and maintains the natural state of rhizosphere microorganisms; greatly reduces the labor intensity and number of workers for plastic film covering; achieves good effects of isolation, pest control, and disease prevention.
