Problems solved by technology

The method of using the screen, because the fixing of the screen will bring troubles to the use, such as placing seeds, supplementing or replacing the culture medium, etc., especially for the dynamic observation of root growth; when using foam boards, the foam boards are easy to break And it is not conducive to high-throughput large-scale standardized testing and dynamic observation of root growth
If the open container is not well covered during cultivation, the water evaporation will be large, and it will easily cause the salt concentration in the treatment group to increase, thereby increasing the system error and affecting the test results.

Embodiment 1

[0045] A method for cultivating peanut seedlings in sand hydroponics, wherein the cultivation temperature is controlled at 26±1°C, the humidity is maintained at 50%±2%, and the photoperiod is 18h / 6h. Specific steps are as follows:

[0046] Step 1: Wash 30-50 mesh quartz sand with tap water until the water is completely clear, then drain, and expose to the sun for two days before use.

[0047] Step 2: Select uniform and plump peanut seeds, and use carbendazim dry powder to dress the seeds to prevent and control crop diseases caused by fungi.

[0048] Step 3: Soak the prepared quartz sand with deionized water, then remove it from the water and drain until it stops dripping, take a sand culture box 1 with a hole in the bottom, and lay a layer of 1cm thick wet quartz sand on the bottom .

[0049] Further, the structure of the sandpocket box 1 can be found in Figure 4 and Figure 5 , its bottom is provided with 20 radicle holes 12, and the radicle holes 12 are evenly distribut...

Embodiment 2

[0060] A method for cultivating peanut seedlings in sand hydroponics, wherein the cultivation temperature is controlled at 26±1°C, the humidity is maintained at 50%±2%, and the photoperiod is 18h / 6h. Specific steps are as follows:

[0061] Step 1: Wash the quartz sand with tap water until the water is completely clear, then drain the water, expose it to the sun for three days, and use it for later use. In this example, three particle size grades of quartz sand are used, and the weight ratio is -30 mesh to +35 mesh. Accounted for 15%, -35 mesh ~ +40 mesh accounted for 25%, -40 mesh ~ +45 mesh accounted for 60% (each mass proportion can be ± 3%), screening and grade ratio can be carried out before cleaning or It can be done after washing, and it is better to do it after washing.

[0062] Step 2: Select uniform and plump peanut seeds, and use carbendazim dry powder to dress the seeds to prevent and control crop diseases caused by fungi.

[0063] Step 3: Soak the prepared quartz...

Abstract

A method for sand hydroponic cultivation of peanut seedlings, comprising the following steps: cleaning quartz sand, dressing seeds, laying quartz sand in a sand culture box (1), placing peanut seeds, continuing to cover peanut seeds with quartz sand, The cultivation box (1) is placed in the hydroponic box (2), and an arch shed (3) is built, then the plastic film is removed, and the culture solution is replaced. This method combines sand culture and hydroponics, with sand on top and water (culture solution) on the bottom, which not only ensures the upright growth of peanut seedlings, but also facilitates taking out the sand culture box to replace the culture solution and taking samples to observe the peanut adversity physiology or The influence of nutrient elements on the growth of peanuts, through the strict control of the environmental conditions of peanut seedlings and the scientific design of planting spacing, covering conditions, and air-permeable and light-transmitting conditions, the success rate of cultivation and the growth rate of seedlings are guaranteed, and the controllable cultivation conditions are improved. The sand culture box, hydroponics box and arch shed used in the cultivation have simple structure, convenient production, and are suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of hydroponics and sand culture at the seedling stage of crops, in particular to a sand hydroponics cultivation method for peanut seedlings which are used in combination with a sand culture box and a hydroponics box. Background technique [0002] In laboratory experiments, hydroponics and sand culture methods are mainly used when studying the regulation of crop seedling stress physiology or nutrient elements on growth. [0003] Hydroponics is the use of water to grow crops. Because the nutrients absorbed by the crops must be soluble in water, the nutrient absorption of the plants in this method is very fast, and the crops grow very fast. But water is a kind of fluid, which has no function of supporting crops to stand upright, making it difficult for crops to grow upright normally. In addition, crops soaked in water for a long time may rot due to lack of oxygen in the roots. [0004] The sand for sand culti...
