Planting method of Begonia verticillata

There are many kinds of crabapple flowers, one of which is Begonia. Today we are going to introduce the planting method of Begonia. Let's take a look at it.

Planting method of Begonia verticillata

1. Prepare

The seeds are washed and soaked with clean water, tomentose, impurities and blighted floating points. in addition, the seeds are filled with ripe seeds. Will soak seeds and wet sand mixed to choose pure mixed sand, first wash with clean water, and with 0.5% carbendazim disinfection, maintain humidity to hands as a group, loose powder, is desirable, sand ratio of 1:3, fully stir evenly. In the new year, put the mixed sand seeds in ventilated containers or boxes and put them in 3-5 ℃ indoor to survive the winter. Sand seeds, should pay attention to temperature, humidity conditions often observed, spring flipped several times to prevent germination or decay, if found rotten seeds must be timely spare parts.

2. Preparation

In the seedling stage, the selection of flat terrain, thick soil, convenient drainage and irrigation in sandy loam, cultivated soil before winter cooking, per 667m2 application of 3 square soil miscellaneous fertilizer, potassium fertilizer 50 kg or 30 kg ferric phosphate, 15 kg, 10 kg, carbofuran, ploughing and raking fine, uniform, irrigation.

3. Seed germination

At the beginning of the second year, the seeds treated with sand were removed, the sand was removed, zero roots were removed, soaked in water for 12 hours, the seeds were removed, spread out in the leeward, covered with transparent plastic film, sealed around and placed for 6 to 8 days. Need to flip every 1-2 times, and rinse the seed surface mucus with warm water to facilitate seed breathing, 70% of the seeds planted when the seed mouth is split.

4. Sowing seeds

The seeds can be sown before and after the sting. Wide and narrow line the width of the selected north-south line is 50 cm, 30 cm, narrow row, a row of about 2 cm deep, sowing about 2 kg every 667 m, if the moisture can be sowed directly, if the moisture is almost in the water in the small ditch, then sow, cover the soil with a thickness of 1.5 cm, and then cover the agricultural film.

5. Rootstock

The main results are as follows: (1) 7-10 days after sowing, begonia germinates at 90%. When the bud has 2 leaves, it begins to exhaust through the through hole, the best time is after 10 o'clock or 15:00 in the afternoon, the saplings around ventilation 3, followed by wet soil hole cover.

(2) Seedling transplanting in mid-April, when Lex Zhang Miaoru has three leaves, it needs refinement and transplanting, thinning generally stick to, keep the principle of tidiness, plant spacing should be kept at about 16 cm, 210000 plants per 667m, Mianmiao local temple rice guitar and fine transplanting, try to make the root soil planted with a lot of water, in order to survive.

(3) Comprehensive management, when the seedling height is 15 to 20 centimeters, it can be used to irrigate and fertilize, watering and fertilizing the amount of urea, 667 square meters of urea is about 10 kilograms, July 6, every dose of urea, every 15 kilograms, irrigation immediately after each fertilization, during which the buds need to be removed in time to reduce nutrient consumption. Pay attention to the prevention and control of diseases and insect pests at the seedling stage, 0.1% methyl topiramate, liquid spray or root irrigation can be used; the main pests of Spiraea chrysanthemum aphid are seriously harmed, which occurs in 0.033% of the park head lice solution to control aphids.

6. Transplant

(1) preparation for grafting scion and rootstock before connection. Select robust growth, full of vertical begonia development branches as scions, cut branches to remove leaves and young bamboo shoots, pay attention to keep 1 cm long petiole, operation and inspection of the graft to survive. Put the scion buds upright in the shadow of the leeward, the lower part with wet sand, the upper part is often spray-dried. Put the branches on the bucket, fight to 10 feet of water, cover it with a wet cloth and get along with each other. Grafted seedlings before transplantation should be lower than lovely branches cut off from the base, and 1 spray disinfection, insecticides, to prevent diseases and pests after. Then, watering the garden once in the first 4 days is best with less water, so that the skin and rootstocks can be grafted to survive.

(2) the grafting time and method are from late June to early July, when the magic diameter is about 0.5 cm, the "T" shaped bud grafting method is connected to the plastic film and sealed, and only the petiole is opened.
