1. Apply 2500-5000 kg of organic fertilizer per 666.7 square meters when planting the land preparation, with a width of 100-150 cm, flat surface, 30 cm wide and 10 cm deep. Usually sowing from late April to early May, the seeding rate is 66 grams per 666.7 square meters, 4-5 days after sowing can be planted. 2, Ding Miao 6-8 days after emergence, seedling height of 3 cm or so, there are 4 true leaves, and time seedlings will be Dingmiao, pull thin thin seedlings, leaving healthy seedlings, Dingmiao spacing 7-10 cm. 3, after the field management Dingmiao, combined with weeding, apply a thin human excrement, each 666.7 square meters Shi 1000-1500 kg. Afterwards, we will do a loose soil weeding and fertilization every Sunday. Each harvest will be applied once fat. 4. The best time for picking and picking is when the buds of the main and lateral branches are exposed, picking the tender stems more than 4 centimeters from the ground. At this time, the quality is good, the yield is high, the tenderness is not old, and the nutrition is abundant. If it is harvested for the second time, it will be carried out in the first half of the month after the first pick, and then it will be picked up and so on. 5. Keep seedlings selected for growth. Sterile red stem cauliflower leaves are preserved, and preserved white cauliflowers are not picked, allowing natural flowering results without any isolation. After about 30 days, the seeds will develop and become mature. Each 666.7 square meters of seed can be produced. More than 50 kilograms, mature seeds dried threshing, can be used in the year or every other year.
Carbomer is an acrylic resin obtained by cross-linking pentaerythritol with acrylic acid. It is a very important rheological regulator. After neutralization, carbomer is an excellent gel matrix, which has important applications such as thickening suspension. According to the dry product calculation, including carboxylic acid group (-cooh) should be 56.0 % ~ 68.0%.
Common carbopol series include: Carbopol 940, 941, 934, 1342, 980, ETD 2020, AQUA sf-1, Ultrez 21, Ultrez 20, etc.
