Yellow cauliflower is a perennial herbaceous plant, and its flower buds are rich in nutrients and flavor. If picked in time, reasonable processing, it is a delicious dish on the table. Now its productive cultivation and fresh processing technology is introduced as follows:

Cultivation and management technology

First, the ground to apply basal fertilizer. Yellow cauliflower root system is developed, tiller faster, requires a more loose and deep soil, before transplanting to turn over about 3O centimeters deep, combined with turning over the ground paved with soil fertilizer 5OOO a lOOOO kg, calcium superphosphate 5O a 75 kg or diammonium phosphate 5O kg, potash l5 a 25 kg. After tilling, harrowing the soil, leveling the field, so that on the virtual bottom solid.

Second, transplanting. Transplanting is divided into spring and fall planting, but fall planting is better. Fall planting should be carried out in mid-September, spring planting in late March is most suitable. Before transplanting, you have to divide the plants. Choose more buds, good quality, l5-2O day-old tillers more clusters, all or part of its rooted out, and then according to the tiller section root from the shortened stem separation, cut off the roots have been senescent, and the roots can be properly cut short as a seedling transplantation. Yellow cauliflower growth time is long, it is generally appropriate to use wide and narrow rows of planting, wide rows of 7O centimeters, narrow rows of 35 centimeters, hole spacing of 35 centimeters, the use of triangular or pair planting method, each hole of 3 or 4 plants is appropriate. Transplanting should pay attention to the depth, generally l5 l7 centimeters better. Too deep is slow tillering, full harvest delay. Too shallow is a small seedling weak, not high yield.

Third, field management

1, plowing: plowing should be carried out three times a year. The first time in the spring after germination. Plowing should be combined with fertilizer, loosening the soil, turning and burying fertilizer to promote the vigorous growth of seedlings. The second time is carried out after the yellow cauliflower has been picked, and this thinning is mainly to eradicate weeds, loosen the soil and accept rainwater. The third time should be carried out after cutting the leaves, mainly congestion, to ensure that the root system can safely overwinter.

2, watering: yellow cauliflower is drought-resistant, but can not lack of water in the flowering period. There are irrigation conditions can be watered 2 or 3 times during the flowering period. Yellow cauliflower seedlings do not tolerate flooding, if there is heavy rain or water in the field, it should be drained in time.

3, bud: yellow cauliflower often due to insufficient or untimely supply of water and fertilizer caused by bud drop. In order to prevent bud drop, in addition to good tillage, fertilization and moderate watering, the following measures can also be used: l% of the 2,4 a d original solution diluted 6OOO times the full range of spray wine plants, or with 3O?lO mg / kg "ba" growth hormone in the first - after the opening of the flower spray wine, and then every 7-8 days to spray a time,*** spray 2 a 3 times.

4, cut off the scape and old leaves: after the buds are picked, cut off the scape and old leaves. In the fall, the leaves will be cut off when the leaves wither, but also the next spring when the germination cut dead leaves.

5, the main diseases of yellow cauliflower are leaf blight and leaf spot disease: choose high and dry terrain, well-drained plots, before the onset of the disease should be sprayed to protect, such as l:l:lOOO times Bordeaux liquid, 5OO a 6OO times 65% zinc daisen, 7 a lO days to spray a time, sprayed for 2 a 3 times. The main pests are aphids, red spiders and grubs. 5O% anti-phidwell wettable powder with 4O kg of water spray can effectively control aphids. 5O% phoxim emulsifiable concentrate 3OOml mixed with 3O kg of fine sandy soil, with the plowing turned into the soil, can effectively kill the underground grubs. Stone sulfur compound can inhibit red spider infestation.

Fourth, picking. Yellow cauliflower is successive buds, successive flowering, so it should be harvested every day. Harvesting time is 3-5 pm. Harvesting requirements buds light yellow, yellow petals longitudinal groove obvious, the mouth of the flower is not cracked.
