Culture method of coriander

Abstract

A culture method of coriander is characterized by comprising the following steps: (1) tilling and applying a basal fertilizer; (2) bedding; (3) applying a preemergence herbicide before sowing ; (4) preventing diseases and insects before sowing, wherein, scale insects are killed by a pesticide 1-2 days before the sowing; (5) soaking seeds and accelerating germination, wherein, the time of soaking the seeds is synchronous with that of the tilling and the bedding, and the time of soaking the seeds is shorter; (6) sowing ; (7) planting at a proper time, wherein, seedlings are established at a spacing between seedling rows of 20*15cm or 20*20cm after the seedlings grow up to about 10cm, and the spare seedlings are removed for food; (8) field managing; and (9) harvesting. The method overcomes the defects and the disadvantages of the traditional cultivation techniques, that is, applying the preemergence herbicide after sowing and before seedling emergency, using a small amount of seeds, spending a long time on the seed soaking and the germination acceleration, applying little basal fertilizers while applying much additional fertilizers and providing no method for preventing the scale insects. The method can help culture the coriander with high yield and good quality.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a coriander cultivation method. Background technique [0002] Coriander is also known as coriander and mustard. [0003] Coriander likes to be cold and cold, and has a certain cold resistance. It can grow at -1°C, but it is not heat-resistant. The optimum temperature for growth is 15-20°C. It grows slowly above 20°C, and stops growing above 30°C. [0004] The traditional method of cultivating coriander has the following deficiencies: ① applying pre-emergence herbicides after sowing and before seedlings has a great impact on the germination of coriander spores; ③The time for soaking seeds to accelerate germination is 12-15 days. If the time is too long, the roots and buds will grow, which is inconvenient for sowing operations and affects the survival rate of seeds; ④The base fertilizer is 5 kg of compound fertilizer and 10 kg of superphosphate per mu. Base fertilizer and heavy topdr...

Problems solved by technology

[0004] The traditional cultivation methods of coriander have the following deficiencies: 1. Apply pre-emergence herbicides after sowing and before seedlings, which has a great influence on the germination of spores of coriander; ③The time for soaking seeds to accelerate germination is 12-15 days. If the time is too long, the roots and buds will grow, which is inconvenient for sowing operations and affects the survival rate of seeds; ④The base fertilizer is 5 kg of compound fertilizer and 10 kg of superphosphate per mu. Base fertilizer and heavy topdressing fertilizer are not suitable for the growth law of coriander; ⑤ no control method for scale insects is proposed
