Abstract

The utility model relates to a melon and vegetable seedling-stage protecting cover, which is mainly used in cold early spring in the northwest. The melon and vegetable seedling-stage protecting cover is characterized in that the protecting cover is blown into a semicircular shape with flexible plastic, the top of the cover is thinner and can be recessed to form a concave surface, a pore is arranged at the top end of the cover, and the pore is sealed when seedlings are small and can be opened when in need of letting in fresh air. The pore can be sealed by a film when the seedlings are small and can be sealed by waste animal oil when in freezing prevention, and the waste animal oil is melted at high temperature so that manually letting in of fresh air is omitted. Three fixing rods are connected to a lower edge opening and inserted into soil, the edge opening is sealed by the soil, the cover is removed in a big-seedling stage and a high-temperature stage, and the cover is fine in protection and is reusable.

Description

Melon dish protective cover in seedling stage

Technical field

The utility model relates to a kind of melon dish protective cover in seedling stage, is mainly used in the northwest and cools early spring.

Background technology

At present, in NORTHWEST CHINA area temperature abnormality in early spring, cold current attacks often; local melon colza is planted and only utilizes the mulch film protection; be difficult to adapt to market demands melon dish to putting seedling stage, let in air, or lack of water; but the time have cold current to attack; though the peasant utilizes various safeguard measures to produce effect aborning, waste time and energy the cost height can bother; second use is low, and peasant household is difficult to be accepted.

Summary of the invention

In order to overcome a difficult problem on the existing melon dish protection ground production technology; in the Northwest melon dish is early gone public; fill a hole in the market; antifreeze; insulation, phenomenons such as drought resisting can in time be taked safeguard measure; the utility model provides a kind of and protects melon dish normal growth seedling stage in land for growing field crops in early spring, NORTHWEST CHINA area, and the melon dish is early gone public.

The technical scheme that its technical problem that solves the utility model adopts is: it is semi-circular to utilize flexible plastic to be blow molded into, and the cover top is thinner, can press sunken; become concave surface, there is an aperture on the top, is closed state when seedling; need leak informaton and can open, this hole can be sealed with film at seedling, seals with animal waste oil when antifreeze; meet high temperature melt, need not manually leak informaton, following bead connects three dead levers and inserts in the soil; bead closes with grave; to big seedling stage, the megathermal period extracts, and protects and can repeatedly utilize.

The beneficial effects of the utility model are, can make the melon dish not be subjected to freeze injury in little seedling stage, improve temperature, and meeting heat can automatic ventilation; meet and coldly can easily seal air vent, meet drought and depress the top, become concave surface to water, this protective cover is easy to use; economical and practical, heat insulation effect is obvious, can repeatedly utilize.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is the sectional structural map of facing of melon dish protective cover of the present utility model.

1 ventilating opening or 5. protective cover lower edges, water inlet 2. protective cover end face 3. protective cover concave surfaces, 4. protective cover sides, 6. protection dead levers among the figure.

Embodiment:

In the drawings; melon dish protective cover is to use plastic blow molding; or other medium-soft body materials processing moulding; light transmittance can reach more than 70%, becomes an integral body, and ventilating opening 1 is on protective cover top protective cover concave surface 3; protective cover end face 2 belongs to deformation plance; genus acts on printing opacity than the good material of soft or hard matter light transmission, and not having the external force effect during projection can not sink; under the external force; recessed can not own return, can pour water, this hole is a water injection hole; high temperature can ventilate; be ventilating opening, meet colod-application useless animal oil or other and meet the material that heat can melt and seal 4 insulation effects in protective cover side; protective cover lower edge 5 ground planes; tight with a little grave, protection dead lever 6 for the plastic strip of hardness being arranged or adding other materials in addition, plays fixedly protective cover effect by the lower edge bar that prolongs.

Claims

1. melon dish protective cover in seedling stage, its characteristic use flexible plastic is blow molded into semi-circular.

2. melon dish protective cover in seedling stage according to claim 1, it is thinner to it is characterized in that covering the top, can press sunkenly, becomes concave surface, and there is an aperture on the top, need leak informaton and can open, and following bead connects three dead levers and inserts in the soil, and bead closes with grave.

3. according to the described melon dish of claim 1 protective cover in seedling stage, it is characterized in that there is an aperture on the top, seal with animal waste oil when antifreeze, meet high temperature melt.
