Embodiment Construction

[0024] A water-saving and drought-resistant cultivation technology for safflower mulching, comprising the following steps:

[0025] (1) Field preparation and fertilization. The planting site should be planted in high dry terrain and well-drained plots. After the soil is thawed in early spring, prepare the land in time, and apply 2500kg / 667m of decomposed farmyard manure. 2 , DAP 10kg / 667m 2 , urea 8kg / 667m 2 , Deep plowing after evenly spreading, tilling depth of 25-30 cm, and then raking and leveling and suppressing the land to reduce soil water loss to ensure the quantity and quality of seedling emergence.

[0026] (2) Seed treatment. Before sowing, the safflower seeds are soaked with 500-1000 times liquid of 50% carbendazim for 10-20 minutes, then dried and sown, which can effectively prevent root rot and blight.

[0027] (3) Selection of sowing date. Timely and early sowing should generally be completed in mid-March to early April, with a seeding depth of 3-4 cm and ...

Abstract

The invention relates to a water-saving and drought-resistance safflower cultivating technology. The technology comprises the following steps of: 1. field preparation and fertilizer application; 2. seed treatment: soaking and sterilizing the safflower seeds, airing and then sowing; 3. selection of sowing period: early sowing in suitable time, and preferentially completing sowing in middle of March to beginning of April; 4. selection of cultivating mode: sowing in a wide and narrow line way, and cultivating in a spaced planting way; 5. covering with a plastic film; 6. thinning and final singling, breaking the film to make the seedling grow out after the safflower is sowed 6-10 days and emerges; thinning for the first time after the seedling grows 4-6 true leaves; carrying out final singling after the plant grows to 15cm; maintaining the plant distance to be 20-30cm; 7. cultivating and weeding; 8. arranging water discharge operation, and ensuring the field to have no deposited water after raining; 9. controlling disease and pest; and 10. recycling the plastic film. The invention has the advantages of water saving, fertilizer saving, seed saving, labor saving, no nuisance, environment protection, high yield and stable yield.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural cultivation, and relates to a water-saving and drought-resistant cultivation technology of safflower. Background technique: [0002] Safflower (Carththamus tinctorius L.) is an annual herb of the Compositae family. It has the characteristics of drought resistance, salinity resistance, and barren resistance. It is a special economic crop integrating medicinal materials, oil plants, feed and dyes. Safflower corolla is rich in flavonoids and safflower yellow pigment. It is not only a traditional Chinese herbal medicine, but also has the effects of promoting blood circulation and removing blood stasis, clearing the meridian and relieving pain, and is also a pure natural pigment and an ideal raw material for food additives. Safflower oil is not only a special health care product necessary for patients with cardiovascular and cerebrovascular diseases such as hypertension and coronary heart disease...
