Techniques and process of raising seedlings of White Wax Seeds

There are many kinds of plants around us, among which the tree is a very large plant family. We all know that there are many kinds of trees, and their characteristics as well as some height, function and so on are different. White wax is the general name of a kind of tree of Oleaceae. White wax can be seen in many places in the world. The requirement of white wax for growth environment is not too high, so in many places, in addition to its own growth, white wax is planted. The following is to introduce the seed breeding knowledge of white wax.

White wax seed seedling:

1. Seed collection:

Ash blossoms from April to May and matures from September to October. The excellent plants with strong growth and no diseases and insect pests were selected and picked when the Samara changed from green to yellowish brown and the kernels were hard. If the seeds do not fall after maturity, you can cut off the fruit branches, dry the wings, remove sundries, put the seeds in a container and store them in a sterilized, low-temperature, dry and ventilated room.

2. Seed treatment:

White wax seeds have a long dormancy period, and it is necessary to accelerate germination in spring sowing. The methods of accelerating germination include low temperature stratification and rapid high temperature germination.

(1) low temperature stratification to promote budding:

In principle, the depth of the trench is below the permafrost, above the groundwater level, the width of the ditch is 80cm, and the length of the ditch depends on the number of seeds. The ratio of white wax seeds to wet sand is 1 ∶ 2: 3. First spread a layer of 10cm thick wet sand at the bottom of the ditch, then mix the seeds with wet sand thoroughly, and put them into the ditch. The thickness of planting sand is 50~70cm, 10cm off the ground is covered with wet sand, and then covered with soil to make the top look like a roof ridge. Put a handful of straw every 0.7 ~ 1m to facilitate ventilation, and the general treatment time is 60 ~ 80d.

(2) rapid high temperature sprouting:

The seeds without low temperature stratification in winter can be soaked in warm water of 40 ℃, then soaked for 2 days after natural cooling and changed water once a day. The seeds were mixed with 3 times wet sand and put on the warm Kang to accelerate germination. The temperature should be kept at 20-25 ℃, turn every day, keep moist, about 20 days, the sum of exposed radicle and split mouth seeds reach 30% of the total seeds can be sown.

3. Raising seedlings:

(1) sowing and raising seedlings:

Spring sowing should be early, usually from late February to early March. Ditching and strip sowing, the seed amount per 667m?2 is 3~4kg, the depth is 4cm, the depth should be uniform, with trenching, sowing, with soil cover, the thickness of soil cover 2~3cm. In order to make the soil close to each other, the soil was suppressed after covering the soil.

(2) raising seedlings by cuttings:

It was carried out from late March to early April in spring. Before planting, the soil was carefully prepared and base fertilizer was applied to make the soil loose and water sufficient. One-year-old sprouting branches were selected from fast-growing and pest-free young mother trees. generally, the branches were more than 1cm in diameter and 15~20cm in length. The upper incisions were cut flat and the lower incisions were Mal-shaped. 2-3 cuttings were inserted in each hole, so that the cuttings were dispersed, row spacing 40cm, plant spacing 20cm, spring planting should be buried deeply, smashed and less exposed, 4000 cuttings per 667m?2.

The above is for everyone to introduce the relevant knowledge sharing of white wax seed breeding, in the above has been a detailed introduction of white wax seed seedling knowledge, and there are some disease and insect nuisance and other knowledge, white wax is not high requirements for the growth environment, so it is relatively easy to grow. However, we still need to pay attention to a lot of details when raising seedlings of white wax seeds to prevent errors in raising seedlings of white wax seeds, resulting in excessive mistakes. That's the end of the introduction.
