Planting time and technology of safflower

The planting time of Carthamus tinctorius is from early March to early April and from mid-October to the end of November. Planting techniques: Carthamus tinctorius should be planted in areas where the previous crops have been planted with wax gourd or soybean, and sufficient fertilizer can be applied after soil preparation. Sowing can be done by strip sowing or on-demand sowing, and in the later stage, seedlings can be replenished and fertilized rationally. actively control diseases such as black spot, charcoal maggot, root rot, golden needle worm, cricket, ground tiger and other pests.

The planting time of safflower

1. Generally, safflower is sown from early March to early April, or from mid-October to the end of November.

2. When planting, we should select the right ones, and then apply sufficient base fertilizer to sow the land after deep ploughing and turning. After emergence, we should strengthen the later stage management, timely water and fertilizer, intermediate ploughing and weeding, prevention and control of diseases and insect pests, and so on.

II. Land selection and preparation

1. Carthamus tinctorius is a kind of fertile and dry plant, which is suitable for growing in dry land or wasteland, and can grow normally in barren soil, but not in wet, stagnant water and low-lying areas.

2, the best planting land is the previous crops to plant wax gourd, taro, soybeans, and so on, after the harvest, ploughing the soil, raking the soil flat and fine, making the soil loose, so as to improve drainage, and then apply about 1000 kilograms of rotten farm manure per mu, with about 15 kilograms of superphosphate.

Third, sow seeds at the right time

1. Safflower can choose suitable sowing time according to different regional climate, spring sowing, autumn sowing and winter sowing, generally winter sowing in Jiangsu and Zhejiang, lower temperatures in Xinjiang and Northeast China, and autumn sowing in Shandong.

2. When sowing, high and low beds can be made according to the specific terrain, and each row can be made into two rows, sowing by strip sowing or sowing on demand, sowing about 6-7 seeds according to a certain distance between plants, and then covering soil and watering. Seedlings will emerge in about 14 days, and the amount of seeds per mu is about 1.5-2.5 kg.

IV. Post-management

The main results are as follows: 1. When the seedlings grow to 6-7cm, you can start to remove the weak seedlings and leave only strong seedlings. Generally, 2-3 strong seedlings can be left in each hole. If missing seedlings are found, the seedlings should be replenished in time.

2. When the seedlings grow 4-5 leaves, a thin farm manure should be applied once. In order to prevent the seedling from lodging, fertilizer should be applied from the root of the plant. Topdressing can be carried out before and after waking, and about 500-600 kg of farm manure can be applied per mu.

V. Prevention and control of diseases and insect pests

In the process of safflower growth, the main diseases are black spot, charcoal maggot, root rot and so on. The more common pests are golden needle worm, cricket, ground tiger, grub, mole cricket and so on. These diseases and insect pests will affect plant growth to a certain extent, and even lead to death. Therefore, it is necessary to prevent in advance and control the disease in time when the disease is found.
