Where can I sell cauliflower seedlings? What are the methods of raising seedlings?

Cauliflower, also known as golden needle lily, is regarded as a local specialty in many areas of our country. Cauliflower tastes sweet and cool, and has the effects of hemostasis, anti-inflammation, heat-clearing, dampness, digestion, eyesight, peace of mind and so on.

First, how to select the seeds of cauliflower?

1. Mengzi flower

Also known as Dazhuahua, it is a cultivated variety of cauliflower in Qidong County, Hunan Province. Medium maturity, the whole growth period is 190 days, the leaf is erect, dark green, 75-95 cm long and 13-17 mm wide. The buds are yellow, 10.5-13 cm long and 7-8 mm thick. Every 50-60 sun-dried flowers are 50 grams, with a drying rate of 18%. The flower flower is about 110 centimeters high, and each flower can pick about 60 buds. It has strong drought tolerance, few insect pests and fast tillering. 90% of the Qidong cauliflower planting base is the cultivation of Mengzi flower varieties.

two。 White flower

Baihua is an excellent variety of cauliflower in Qidong County, Hunan Province. Medium maturity, the whole growth period is 196 days, the leaves are straight, light green, 91 cm long, 110 cm long, 19 mm wide, 150 cm high, 100 flowers per flower, harvested in early June and ending in early September, about 90 days long. The bud is 10-11 cm long and 6-8 mm thick. The dried flower is light yellow and the flower mouth is red. The drying rate is 22%. Strong insect resistance, drought tolerance, fast tillering, few buds, strong bud regeneration, up to 400 kg per mu of dried vegetables.

3. Chong Li Hua

Chong Li Hua, also known as big leaf flower and black mouth flower, is one of the main varieties in Qidong County, Hunan Province. The growth potential is strong, the leaves are soft, and most of them are zigzag and drooping from the middle of the leaf body. The flower is about 150 cm high. The harvest began in mid-late June and finished in early September. The harvest time is about 70 days. It has strong drought resistance and few buds. The buds are large, up to 12 cm long, the perianth is thick, and the drying rate is high. Every 60 buds can dry flowers 50 grams, 5.5 kilograms fresh buds dry flowers 1 kilogram. The flower bud is yellow, but the tip of the mouth is slightly purplish red, and it is dark brown after drying, commonly known as black-billed flower, with low grade and slow tillering. It takes a long time to enter the flowering stage after planting, but there are more years of continuous harvest after planting. The yield is high, generally producing 350 million 400 kg of dried vegetables per mu, and the high one can reach 475 kg.

Second, what are the methods of raising seedlings of cauliflower?

1. Ramet propagation

Ramet propagation is the most commonly used method of reproduction. One is to dig out all the mother clumps and replant them, and the other is to dig out part of the plants on one side of the mother clumps to make seedlings, leaving them to continue to grow.

When digging and dividing seedlings, it is necessary to hurt the roots as little as possible, and then plant seedlings with digging and dividing seedlings. After the seedlings are dug up, the soil should be shaken off, one by one, or every 2 or 3 buds into a clump, broken off from the mother plant. Cut off the old root, rotten root and diseased root growing in the lower part of the rhizome, retain only 1-2 layers of new root, and cut off the overlong root, leaving about 10cm length.

two。 Sliced seedling propagation

After the harvest of cauliflower, dig out the root plant, and then separate according to the bud, remove the hairy leaves around the shortened stem, the dead leaves, and then leave the leaf length 3~5cm, cut off the upper end; then use a knife to cut the rhizome longitudinally into two pieces, and then determine whether each piece needs to be subdivided according to the thickness of the rhizome. If the rhizome is strong, it can continue to be cut longitudinally into several strips. In this way, each plant can be divided into 2 to 6 plants, and as many as 10 plants. It should be noted that when cutting, each seedling piece should have a "seedling stem" on the top and a fibrous root on the bottom. After cutting, soak the seeds with 1200 times solution of carbendazim and disinfect for 1 h. After being exposed to the sun, mix the seeds with fine soil or plant ash mixed with loess to raise seedlings.

3. Cuttage propagation

After the harvest of cauliflower, select the bract bright green from the middle and upper part of the flower, and if the growing point under the bract is obvious, leave 15cm around the growing point, and cut it into the soil in a slight arc, so that the upper and lower ends of the bract are buried in the soil, so that the part of the bract with a growing point is exposed to the ground and slightly covered with fine soil for protection; or it is obliquely inserted at an angle of 30 °, and the depth is appropriate to cover the strict buds with the soil. The cuttings cut on the same day had better be finished on the same day, in case the cuttings lose water and affect the survival. The cuttings must be watered thoroughly on the same day and the next day after insertion so that the cuttings are closely connected with the soil. In the future, the soil moisture should be kept at about 40%. After about 1 week, it can take root and sprout. Guard against the cold at the beginning of winter. After one year of cultivation, there were 12 tillers per plant and at least 5 tillers, which could blossom in the next year.

4. Seed propagation

Artificial pollination was carried out by 10~60min after flowering. The suitable temperature for fertilization of cauliflower is 2832 ℃, and the relative humidity is 53%-82%. In order to prevent the natural hybrid "string of flowers", thread can be used to tie the buds. But should not cover the bag, lest the temperature in the bag is too high. In order to increase the fruit setting rate, 0.1% borax, or 1% potassium dihydrogen phosphate, or 2% superphosphate, or 1% urea and potassium chloride can be foliar sprayed every 7 to 10 days from 2 days before flowering until 20 days after the last batch of capsules are set. The fruiting rate of the apical branch and the second branch of the main inflorescence was the highest. From the point of view of the node position, the fruit rate of the first and second fruit nodes is the highest. For this reason, for the first to fourth branches, the buds on the first to fourth fruit nodes can be retained, the buds on the first and second fruit nodes can be retained in the top branches of the main inflorescence, and the rest of the buds should be thinned so that nutrients are concentrated in the fruit and grains.
