The optimum temperature for strawberry seedling growth was 25 ℃ ~ 30 ℃, and the stolon stopped growing when it exceeded 32 ℃. Therefore, in the early stage, the greenhouse should do a good job of heat preservation, improve the air temperature and substrate temperature, and promote the early emergence of stolons. In the southern region, the temperature from mid-May to early July is suitable for the occurrence of stolons, during which the number of stolons is large and the interval between stolons is short. From mid-July to August, with high light intensity and high temperature, the greenhouse should be covered with a sunshade net with a shading rate of 60% from 9 am to 5 pm every day, so as to reduce the temperature and ensure the normal growth of mother and offspring. In addition, moderate shading in the later stage of seedling cultivation can meet the low temperature and short day conditions needed for strawberry flower bud differentiation and promote strawberry flower bud differentiation.
It is recommended that the length of the extension should not exceed 5 meters. Among all the sunshade products, the canopy is a good partner for the sunroom. Outside sunshade electric double-track ceiling curtain: electric double-rail folding ceiling curtain is a sunshade system that can be retracted and put on the top or oblique side glass window frame of indoor lighting roof, that is, double-rail translation system. If the daylighting of the balcony at home is on the middle side, it is recommended not to use full shading curtains, but to use semi-shading curtains, so it is appropriate to choose whether shading is needed or not. The color of the space tends to be simple and pure. Plus the silver-gray sunshade looks like a perfect match.
Do a good job in greenhouse reinforcement, heat preservation and warming. Such as using double film to cover cultivated mushrooms, press the outer plastic film to prevent air leakage. Check and reinforce the scaffolding to prevent heavy snow from collapsing. When necessary, measures such as removing the covering (such as the outer sunshade net) should be taken to reduce the pressure of the mushroom shed and reduce the loss.
The car key door can be pulled out in two different gears, one of which is powered by a CD player. I just got it and changed a battery when I ran out of power. When I first got it, there was a noise in the back of the rear seat, the right rearview mirror was loose, the electric adjustment of the rearview mirror failed, the speedometer did not work (the fault was cured after changing the battery), the CD machine did not read the disc smoothly, and the front fog light was not lit. The rearview mirror reading lights and sunshade make-up mirror lights are not lit (the front car owner did not connect the line when the roof was packed), the rising window of the right front window was slow, and the valve chamber cover and steering power tubing leaked oil.
6. Energy saving and environmental protection: electric shutter windows can achieve the appropriate indoor temperature by adjusting sunshade, which can effectively reduce the heat load of air conditioning, absorb solar radiation energy and reduce heating load in winter, thus playing the role of energy saving and consumption reduction. 5. Heat preservation and heat relief: electric shutter windows can effectively prevent strong outdoor light, maintain a steady state for indoor temperature, and are more suitable for work.
Scope of application: polyurethane foam is widely used in automotive interior decoration and vibration absorbing parts, such as coating materials, polyurethane rigid plastic panels, polyurethane elastomers, seat soft foam materials, decorative parts, sofa leather, roof accessories; the most widely used is a variety of soft and hard polyurethane foam materials, which have vibration isolation, sound insulation, noise reduction, thermal insulation and thermal insulation.
