1. Seedling cultivation time

There are two main time periods for cucumber seedling cultivation. Sowing can be carried out in early spring from January to March. At this time, the climate is mild and the growth rate is fast, which is very important. Conducive to germination and emergence. Another time is from June to August in summer and autumn, when the climate is cool and pleasant, which is also helpful for vegetable growth.

2. Select seeds

According to local climate conditions, select suitable seeds to ensure high quality, screen the seeds, and pick out shriveled and damaged seeds. After selecting the seeds, you cannot sow them immediately. They need to be processed. Soak the seeds in hot water, keep the temperature at about 55 degrees, and take them out after about half an hour. After washing with clean water, soak in clean water for 6-8 hours, then wrap it in wet gauze and place it in an environment of 25-30 degrees for germination. After 2-3 days, white dew will appear, and you can sow seeds at this time.

3. Sow seeds

Prepare the seedling plug tray. You can mix peat soil, perlite, and vermiculite in the same proportion to ensure it is fertile, loose, and breathable. Add some at the bottom. Organic fertilizer. After preparing the soil, water it thoroughly, sow the seeds on demand, cover it with a thin layer of soil, about 0.5-1 cm, and adjust the surrounding temperature to 24-30 degrees.

Methods for sowing and raising seedlings from Ginkgo seeds

1. Methods for sowing and raising seedlings

1. Seed selection: Seedlings cultivated from small particles of seeds will also be small and slow to grow. It is relatively weak, so be sure to choose large seeds, so that the seedlings grown will be stronger and their growth in the later period can be guaranteed. Among these seeds, there will be some shriveled ones. The simple way to pick them out is to pour them directly into clean water, soak them for about ten minutes, and throw them away if you see any ones floating on them.

2. Germination: Soak the selected seeds in water at room temperature for about two to three days, and change the water once a day. Take out the seeds and put them on plastic paper. Use a small watering can to sprinkle water every morning or evening to keep the seeds moist. After a week, they will sprout.

3. Sowing: The selected substrate must be deep and breathable, preferably sand or loess. Dig a small trench and place the seeds crosswise inside.

2. Seedling breeding time

Subtropical areas can choose from early to late March, and temperate areas can choose from late March to mid-April.

Methods for raising Evodia Evodia seeds

1. Seed propagation. Seed propagation of Evodia is actually very rare in current production and planting. The first is that the seeds of Evodia are not very easy to collect, and the second is that the germination rate of Evodia seeds is not very good, and the growth rate is very slow, requiring more energy. But if we must sow seeds, it is not impossible. We need to purchase good seeds, and then germinate the seeds before raising seedlings, so as to ensure the emergence rate of Evodia rutae.

2. Propagation by root cuttings. The propagation of Evodia by root cuttings generally requires the selection of a single plant of good quality that has lived for more than four years, has a well-developed root system, vigorous growth, no pests and diseases, no mechanical damage, and is of good quality as the mother plant for propagation. Dig out the selected mother plant, cut the lateral roots into small sections, about fifteen centimeters in length, and then insert the prepared sections diagonally into the seedbed for cultivation. Finally, pour excrement water into the seedbed, cover it with straw or mulch, and wait for seedlings to emerge later.

How to raise chayote seeds

1. Time

When raising chayote seeds, you must choose the right time. If you plant them randomly, it will not only reduce the survival rate, and will also affect later growth and yield. Generally, planting is mostly carried out in April and May in spring, and the specific adjustments should be made according to the local climate. However, if you want to plant it in a greenhouse, you can plant it in March.

2. Soil preparation

It likes to grow in a warmer environment, and the planting place must have sufficient light. In addition, the soil must also meet the characteristics of air permeability and good drainage capacity, and try not to have large pieces of soil in the land. After finishing the soil, apply some farmyard manure to it to make the soil more nutritious.

3. Seed selection

You must buy good quality seeds. Their growth cycle is relatively long, so if the seeds are of poor quality, they will easily die during the growth period. After selecting the seeds, put them in warm water, soak them, take them out and soak them in chemicals, and finally take them out and rinse them thoroughly.

4. Sowing

When sowing seeds, you can use hole sowing, that is, put them into the soil and then bury them with soil. You need to pour some water when covering the soil, and finally, if you wait patiently, seedlings will grow.

How to squat cucumber seedlings when raising seedlings

1. Methods of squatting seedlings:

2. First, control water. During the vegetative growth stage, keep the soil neither too dry nor too wet. If it is too dry, it is advisable to pour small amounts of water instead of flooding with large amounts of water.

3. The second is fertilizer control. It is advisable to use biological bacterial fertilizer for seedling promotion. If the base fertilizer is insufficient and affects normal growth, the method of eating less and eating more often should be adopted, and the amount of fertilizer applied each time should not be too large.

4. The third is cultivating. Cultivating can improve the rhizosphere environment and promote rooting, but when cultivating, the roots of the plants must be shallow near and deep at the distance without damaging the roots.

5. Period of squatting: squatting should be started gradually according to the growth of the seedlings after planting and slowing down. The squatting should be ended under the following circumstances and transferred to reproductive growth management: cucumbers and bitter melons should be transferred to reproductive growth management after the first female flower blooms. .

6. Notes:

7. First, the length of time must be grasped and implemented flexibly according to plant growth, moisture content, weather changes, etc. The soil holds a lot of water and is fertile, so the plants will grow vigorously. It is advisable to plant the seedlings early so that they are not too long and have deep roots and luxuriant leaves. On the contrary, it is necessary to provide the plants with appropriate water and fertilizer, and combine it with cultivating to achieve a combination of supply and control.

8. Second, we should focus on promoting thin seedlings and squat seedlings appropriately to catch up with strong seedlings.

9. Third, after the seedling planting is completed, the plants must be supplied with sufficient water and fertilizer to promote the development of the plants and fruits.
