The latest course of safflower field management techniques and methods

Safflower is a plant belonging to the genus safflower of compositae. Its flowers are used as medicine to promote blood circulation, regulate menstruation, disperse blood stasis and relieve pain. It is helpful to treat amenorrhea, dysmenorrhea and traumatic injury. At present, there are a large number of cultivation in Xinjiang, Xizang and other places in China. How should safflower be managed in the field? Let's take a look at the detailed introduction.

1. Thinning seedlings

Thinning and seedling determination of safflower generally needs to be carried out twice. When the seedlings grow to 10 cm, they need to be thinned once. At this time, the weak seedlings will be removed. Generally, 3-4 seedlings will be left in each hole for hole sowing, and one plant will be reserved for 10 cm for drilling. The second thinning is fixed seedlings, when the seedlings grow to 15 cm, generally 2 seedlings per hole, and one seedling is reserved at a distance of 20 cm. In fixed seedlings after regular inspection, found that the phenomenon of lack of seedlings to timely replanting.

2. Intertillage and weeding

Safflower should be cultivated three times in the whole growth period, the first two times together with thinning and fixing seedlings, and the third time before plant closure. Weeding should be carried out according to the field conditions, especially autumn sowing safflower, seedling stage is longer, should be appropriate to increase frequent weeding, at the same time pay attention to soil cultivation work, so as not to seedling lodging.

3. Fertilizer and water management

Safflower is a fertile plant, in addition to applying sufficient base fertilizer, but also in each growth period reasonable topdressing, so as to obtain high yield. The seedling stage needs too much nitrogen fertilizer, which helps its stem and leaf growth. Therefore, when combining thinning and seedling determination, 1000-1500 kg of thin human and animal manure water is applied per mu. Spraying 0.2% potassium dihydrogen phosphate or 0.5% kg urea before budding promoted flowering and increased yield obviously. Safflower is drought-tolerant and afraid of waterlogging, so it generally does not need watering during its growth period. It can be watered properly during drought in the early stage of growth to keep the soil moist. In rainy season, attention should be paid to drainage to reduce pests and diseases.

4. Pickling

In order to improve the yield, in the growth period of safflower to improve the topping, to promote its multi-branch, there is a significant increase in yield, in order to supplement the plant nutrition consumption, after the topping generally to fertilize. It should be noted that if the planting density is too high and the number of branches is appropriate, it is not allowed to pick the core, so as to avoid the field closing and unfavorable growth.

The above is the introduction of safflower field management technology, I hope to help you, want to know more related knowledge, please pay attention to us.
