Fennel planting method: how to grow cumin? What is the suitable temperature for cumin planting?

Cumin is the main developing cash crop in our state. Many people grow cumin, so how to grow it? Do you know? Below, we will introduce the environmental requirements of cumin cultivation, the morphological characteristics of cumin and the key points of cumin cultivation requirements.

I. Environmental requirements

Fennel likes cold climate and is more drought-resistant, but not moisture-resistant. Because fennel plants are short and the root system is shallow, they are generally distributed in the soil layer of 5-10 cm, and are most suitable for planting on sandy soil with organic matter content of 1.5% ~ 1.8%.

The most suitable growth temperature of cumin was 15-20 ℃. The growth was slow when it was higher than 25 ℃ and inhibited when it was lower than 5 ℃. When sowing, the ground temperature was 5: 10 ℃, the seedlings emerged at 15: 16, and the seedlings emerged at 7: 8 at 12: 15 ℃. Sowing to maturity 85-95 days, flowering to maturity 25-30 days.

Second, morphological characteristics

Cumin belongs to Umbelliferae, annual herbaceous crop, straight stem, cylindrical smooth, pinnate leaves, compound leaves deeply split such as filiform, petiole light green, flower yellow, compound umbels, no involucre and bracteoles leaves, fruit (seed) linear-oblong, smooth solitary, plant growth height 30cm 35 cm, growth period about 90 days. After ripening, the fruit is orange-yellow, bright color and fragrant, with a thousand-grain weight of 2-2.3 grams.

III. Cultivation requirements

1. Land selection

Fennel seeds are small, about 500000 seeds per kilogram, and it is not easy to emerge, so the requirements for land selection and soil preparation are very strict. It is necessary to choose sandy loam with medium and high fertility and containing more than 1.5% and 1.8% organic matter. Do not plant on saline-alkali soil and heavy clayey land. Plots with previous crops of @ # @ 245 grass @, oats or weeds should not be planted.

two。 Soil preparation standard

Fennel seed is small, the top soil strength is poor, in soil preparation, to fine, loose, net, flat, broken, soil moisture standards, soil preparation to plough, Harrow, ploughing combined with one-stop compound operation, so that there is no small pit, no more than 3 cm of soil, no residual film, weeds, stems, soil pine, soil leveling, soil moisture.

3. Sowing time and sowing quantity

Fennel should be sowed sooner rather than later, usually finished in mid-March and early April at the latest. 667 the sowing rate of square rice is 1: 1.5 kg, the sowing depth is 2.5-3 cm, and the 667 square rice with three-material phosphate fertilizer is 10-15 kg.

4. Sowing mode

Fennel is mostly sown by strip sowing or sowing, and strip sowing uses 20 cm equal row spacing or 15 × 30 cm wide narrow row. Can also open ditches to build ridges and sow seeds, or sow seeds in small beds, suppress and increase soil moisture after sowing, and promote strong seedlings.

In recent years, intercropping is often used to interplant cotton, corn, vegetables and other crops to make full use of light and heat resources, improve the multiple cropping index and increase economic income.

IV. Field management

When the seedlings are clearly in line, they should be ploughed in time to loosen the soil, preserve soil moisture, pull out weeds among plants, and rake horizontally in case of rain to facilitate the growth of seedlings. As there are many kinds of weeds in the fennel field and grow fast, they must be removed before the ridge is sealed. If dodder is harmful in the middle and later stage, 40% Dilean EC 200 × 300 times can be sprayed after 5: 00 p. M. and removed manually if necessary.

Fennel has a short growth period, small growth and little need for fertilizer and water. It is generally necessary to apply sufficient basic fertilizer and seed fertilizer before sowing, without irrigation and fertilization. If the soil is barren, spread urea 8kg / 10kg before ridge sealing (3-4 true leaves) combined with irrigation water 667 square meters, adjust fertilizer with water and promote seedlings with fertilizer ​​. In the early flowering stage and filling stage, spraying 2005g potassium dihydrogen phosphate per 667 square meters to promote more fruit setting, more fruit, and improve grain weight. The second water was irrigated at the late flowering stage and early filling stage, and the third water was irrigated at the end of filling stage to promote early maturity. Irrigation should adhere to irrigation in the morning and evening, timely and appropriate amount, avoid high-temperature irrigation, reduce dead seedlings, insist on seedling, land and sky irrigation is the key to high yield of fennel.

Fifth, timely harvest

When the seeds of cumin turn yellow and the stems and leaves wither, they can be harvested. Fennel is easy to fall and break branches, so the harvest should be carried out in the morning or evening.

Now, you know how to plant cumin. In fact, it is not difficult to say it is difficult to plant cumin, and it is not easy to say it is easy to say. It depends on whether you want to grow good cumin.
