The annual production of eggplant in the solar greenhouse is mainly based on cultivating or ordering grafted seedlings for production. The production period is from July to July every year, and in August, the planting in June is planted.

The eggplant seedling work has reached the grafting season, and the grafting survival rate has become the most important concern for the vegetable farmers. It depends mainly on whether the grafting work is done well. In the eggplant seedling work in recent years, many farmers have reported that the eggplant grafting survival rate is very low. According to the investigation, the root causes are: First, it is not possible to choose a suitable grafting period (ie, the age of the rootstock and the size of the scion must be appropriate); then the grafting technique is not strict enough; the third is the management after grafting is unreasonable; Illness work is not in place. So how can we ensure that the eggplant grafted seedlings have a higher survival rate? Based on years of production experience, the author summarizes the following points for reference by the majority of farmers.

There are nine steps in the grafting process:

The first step: to prevent disease before grafting. 1 to 2 days before grafting, carefully squirt the rootstock seedlings and eggplant scion, such as sputum 20 grams of Gaplik 20 ml of Jiafu Shizhuang 15 ml of water 15 kg. It can effectively prevent the occurrence and prevalence of diseases such as epidemic diseases, sclerotinia sclerotiorum and stem blight.

The second step: shading before and after grafting.

Cover the shade net or the grass curtain over the grafting site or the seedbed before grafting. The scattered light was seen in the seedbed from the start of grafting to the 8 days after grafting. Especially after the grafting at noon to the nursery shed, the sunshade net or the grass curtain is blown by the wind to avoid the seedlings being exposed to strong light. After 8 days, depending on the healing condition of the grafted wound, you can see the light in the morning and evening before and after noon every day, and gradually increase the time of seeing the seedlings. After the seedlings survive, the seedlings should be properly strengthened.

The third step: the grafting period should be appropriate.

Grafting can be carried out when the rootstocks are 6 to 7 leaves. When selecting the scion from the old eggplant, pay attention to the selection of branches that are semi-lignified, disease-free, strong, thick and rootstock.

The fourth step: grafting clip disinfection. Grafting small clips should be soaked with high concentration of 20 ml of carbendazim for 2.5 hours on water before grafting, or simmered with boiling water for half an hour. Remind the vegetable farmer friends to choose a small round folder, it is forbidden to use rubber band or wrap film instead of small clip, otherwise the grafted wound will be poorly breathable, easy to germinate, lurking at the interface; plus high temperature, high humidity and other adverse environment The condition is that after the planting, the black heart and the dead branch of the stem of the plant stem are buried.

Step 5: Before grafting, the rootstock seedlings should be properly controlled. The rootstock seedlings should be in a state of slight water shortage before grafting, so that the juice at the incision is thick and conducive to the survival of the grafted seedlings. After the grafting, the water is poured, and the juice flows between the rootstock and the scion faster, which is more conducive to the healing of the grafted wound.

Step 6: The incision should be tight. When grafting, a new razor blade should be used. The rootstock seedling should be cut 1 to 1.5 cm deep, and the scion should be cut into a 30-degree wedge shape. The length of the cut surface is 1 to 1.5 cm. Then insert the scion into the rootstock incision. At this time, the most important point is to pay attention to the scion and then gently apply a force to the lowest part of the rootstock incision, so that the interface is tightly bonded, which is more conducive to improving the survival rate of the seedling.

Step 7: After the grafting, the edge mask film is poured. After the grafting, the seedlings are placed on the seedbed. After each pendulum, the 7-fold liquid is used to pour the nutrient cup, and then the membrane is covered.

Step 8: Ventilation. Ventilation is a crucial part of the grafting of the seedlings. Pay attention to the film used for the seedbed. It is necessary to connect the two membranes to the left and right, so that it is easy to release the wind from the top of the seedbed. Remember not to let the wind out from the bottom of the seedbed. If the temperature of the seedbed is above 40 °C, it is recommended to put a small wind on the second day after grafting.

Do not in order to ensure the humidity of the air, do not ventilate for four or five days, so it is easy to cause the water at the marrying interface to rot, and the seedlings are prone to water loss due to excessive evaporation of high temperature. If the ventilation temperature is not high, the temperature of the seedbed is too high, which is one of the main reasons for the low survival rate. Therefore, proper ventilation is required, and the temperature of the seedbed should be controlled at 28 °C ~ 35 °C.

Step 9: Management after withdrawal. The seedling bed was removed in the morning or evening after about 7 days of grafting. At this time, it is necessary to spray medicine and prevent disease in time. 25 g of gold ash, 15 ml of carbendazim, and 1 capsule of fresh amine can be sprayed evenly on 15 kg of water.

Eggplant grafted seedlings generally have a survival rate within 8 days after grafting. It is a foregone conclusion. Hope that the farmers will remember the above points and believe that your grafting work will be more successful.

Fuel Level Sensors

Fuel monitoring is regarded as an important aspect of fleet management; it will assist fleet managers in reducing the large bite of fuel usage in operations.

Your fleet depends on fuel because you need a monitoring system for tracking and evaluating fuel consumption and expense. Fuel management software is intended to measure and manage fuel consumption in various industries. This is where fuel level sensors step in.
