Problems solved by technology

At present, the planting of Coix basically follows the traditional cultivation mode of "seeding direct seeding method". The uniformity of seedling emergence and the quality of seedlings are greatly affected by factors such as variety and environment. The overall level of Coix production is not high and the quality is unstable.
The method of raising seedlings and transplanting has advantages in solving the contradiction between spring and spring, drought resistance (or cold), early sowing and fighting for season, and solving problems such as uneven emergence and low quality of seedlings. It is widely used in the planting process of rice and vegetables; Methods for this are still lacking

Embodiment 1

[0018] An intensive seedling raising method of Coix, comprising the following steps:

[0019] Choose plots with flat terrain and relatively uniform soil fertility. The soil quality is preferably loam or clay. Use machine or manual deep plowing of about 25cm, leveling and raking to make a seedbed with a width of 1.0-1.5m and a height of 10-15cm. Drainage channels are dug to ensure smooth drainage. Select full and clean seeds, and use 80% carbendazim wettable powder for seed dressing and disinfection before sowing. The amount of disinfectant used is 0.4% of the weight of the seeds; sow seeds 30-40 days before transplanting, and the amount of seeds used is 30kg / mu , the transplanting area per acre of seedlings is 10 mu; the application of pure nitrogen 10kg / mu, P 2 o 5 5kg / mu, K 2 O10kg / mu is used as base fertilizer; water after sowing, it is advisable to keep the seedbed moist, and cover with polyethylene film. Remove the film when the seedlings are exposed to the ground and...

Embodiment 2

[0022] An intensive seedling raising method of Coix, comprising the following steps:

[0023] Choose plots with flat terrain and relatively uniform soil fertility. The soil quality is preferably loam or clay. Use machine or manual deep plowing for about 20cm, leveling and raking to make a seedbed with a width of 1.0-1.5m and a height of 10-15cm. Drainage channels are dug to ensure smooth drainage. Select full and clean seeds, and use 80% carbendazim wettable powder for seed dressing and disinfection before sowing. The amount of disinfectant used is 0.5% of the weight of the seeds. Sow seeds 30 to 40 days before transplanting, with a seed rate of 30kg / mu, and the transplanting area of ​​seedlings per mu is 10 mu; apply pure nitrogen 15kg / mu, P 2 o 5 10kg / mu, K 2 O15kg / mu is used as base fertilizer; water after sowing, it is advisable to keep the seedbed moist, and cover with polyethylene film. Remove the film when the seedlings are exposed to the ground and grow to 1-2 cm, ...

Abstract

The invention discloses a coix lacryma intensive seedling growing method, comprising the following steps: selecting land and preparing land; processing seeds; controlling to sow 30-40 days before transplanting, sowing quantity being 30-35 kg / mu; applying pure nitrogen 10-15 kg / mu, P2O5 5-10 kg / mu, K2O 10-15 kg / mu as base fertilizer; watering after sowing, to keep a seedbed wet, after sowing, using polyethylene films to cover; uncovering the films after seedlings are exposed out of ground and grow to 1-2 cm, in 4-6 leaf period, transplanting with soil; about 7 days before transplanting, spraying 50-200 mg / L paclobutrazol solution, and applying urea in amount of 10-20 kg / mu as marrying fertilizer before transplanting to make seedlings strong. The method can shorten seedling growing period and obtain high-quality seedlings, and the method is suitable for large-area popularization.

Description

technical field [0001] The invention belongs to the field of cultivation methods. The invention relates to an intensive seedling raising method of Job's tears. Background technique [0002] Job's tears ( Coixlachryma-jobi L.) for the genus Coix ( Coix L.) is a cereal crop, and it is also one of the medicinal plants with a large cultivation area in my country. For a long time, as a small "grain medicine" crop, Coix has gradually retreated to a semi-wild state. In recent years, with the improvement of people's health concept and the gradual advancement of agricultural structure adjustment, the development of small grains and traditional Chinese medicine industries represented by Job's tears is also in the ascendant. At present, the planting of Coix basically follows the traditional cultivation mode of "seeding direct seeding method". The uniformity of seedling emergence and the quality of seedlings are greatly affected by factors such as variety and environment. The overa...
