Cultivation technique of pure fragrant oil wheat
1. Variety characteristics
The plant has strong growth potential, the plant height is 30-40 cm, and the development degree is 20-30 cm. The leaves are lanceolate, green, about 40cm long and 6~10cm wide. The leaves are smooth, the taste is crispy and the quality is good. They can be eaten raw, fried, and made into soup. The seeds are black, with a weight of about 1g, which is resistant to cold, heat, and convulsions, and has a fast growth rate. The spring and autumn open field cultivation in Beijing area is from 25 to 30 days (days) from planting to harvesting. When the plant grows to a certain size, it can be harvested at any time according to market needs. The output per 667 square meters is 1500-2000kg.
2, cultivation techniques
2.1 Seed Treatment Pure sesame oil Macadamia is a cold-tolerant vegetable. The suitable temperature for seed germination is 15-20 °C. When it is higher than 25 °C, germination is inhibited. In order to improve the rate and uniformity of emergence after sowing, low temperature treatment is feasible before sowing, and low temperature treatment has the effect of breaking the dormancy of the new seeds harvested in the same year, which can effectively increase the seed germination rate. Specific method: the seed is wetted with water in a petri dish or gauze bag lined with filter paper, and placed at a low temperature of about 5 ° C (a refrigerator in a domestic refrigerator) for 2 days (days) and taken out.
2.3 sowing seedbed bed per square meter of fermented organic fertilizer 8 ~ 10kg, ternary compound fertilizer 0.06 ~ 0.10kg, bed soil should be fine and flat, before the sowing, the bottom of the water, until the water seeps down on the bed Spread a thin layer of fine soil. When planting, the seeds were mixed with a small amount of fine tidal soil and then spread, and the soil was about 0.5 cm after sowing. About 1g is planted per square meter of seedbed. In winter and early spring, seedlings are generally cultivated in the protected area. After sowing, the film should be warmed and moisturized on the seedbed. The temperature is 18-20 °C during the day and 12-14 °C during the night. In summer and autumn, it is better to cover the shade net on the shed. When it rains, cover the membrane and protect the seedbed from rain. After the emergence, remove the cover on the seedbed and gradually remove the shade net on the shed.
2.3 seedling period management seedlings after 1 week and time seedlings, seedling spacing 3 ~ 5cm, 2 ~ 3 pieces of true leaves when seedlings, can use nutrient mash and seedbed bed two ways, appropriate water control after slow seedlings, Promote the roots of the defense. If the seedlings are not planted during planting, the second seedlings should be carried out, and the spacing of the seedlings should be about 8cm. Seedlings and seedlings should be poured 1 to 2 days before the planting, so that the seedlings are more soiled, the soil is not scattered, and the roots are protected from damage. From sowing to colonization, it takes 30 to 45 days (days), and winter and spring are slightly longer than summer and autumn. The length of time required is mainly affected by seedling temperature and water management.
2.4 Colonization When the seedlings 4 to 6 true leaves are planted in time, before planting, the leaves of the former crops and the weeds around the ground are completely eliminated, the base fertilizer is applied, the soil is prepared, and the cultivation is carried out. About 15cm square.
2.5 Field management Pure sesame oil wheat vegetable products are soft leaves, keep the soil moist during the growth period, fertilization is based on the base fertilizer, and after planting the seedlings, the leaves can be promoted with the application of the quick-acting nitrogen fertilizer once.
2.6 Pest Control Pests and diseases mainly include downy mildew and leaf miner. When the humidity in the field is too large and the ventilation is poor, the near-surface leaves are prone to downy mildew. Through reasonable water management, avoiding dryness and humidity and excessive cultivation density, it can effectively reduce or avoid the disease, and should be controlled after the disease occurs. Watering, lowering the temperature in the field; removing some plants, adjusting the density, improving the ventilation in the group; spraying DuPont Kelu and other drugs in time. The damage of the leaf miner mainly occurs in the cultivation ground of the spring dew or the insect source. It is necessary to pay attention to the early detection of early spraying. It can be sprayed once every 7 days (days) with 1.8% of the Effort emulsifiable concentrate. Spray 2 times. Protected cultivation should completely eliminate the branches and weeds of the former crops and cut off the source of the insects.
2.7 The harvesting period of pure sesame oil harvested wheat is relatively flexible, and the harvesting specifications are not strictly required. According to the market demand, the principle of high yield and good yield can be determined. In the spring area of ​​Beijing, it is cultivated from the time of planting to harvesting for 35 days (days); it is cultivated in autumn field, and it is harvested and harvested around 25 days (day) after planting.
