Problems solved by technology

Shepherd's purse for quick-frozen processing is most suitable for open-field cultivation in early September to early October in autumn. The quality is good, but it is easy to bolt and bloom, resulting in low yield
During the quick-freezing process, shepherd's purse needs to be blanched, resulting in the decomposition and yellowing of chlorophyll in shepherd's purse, the loss of nutrients, the loss of flavor substances, and the loss of hardness and crispness, thus affecting the taste and overall nutrition

no. 1 example

[0029] A method for planting raw material shepherd's purse for quick-frozen processing disclosed by the present invention comprises the following steps:

[0030] Choose land to make a plot

[0031] Choose a field with high dryness, good drainage, loose soil, sufficient sunlight, and no cruciferous crops have been planted within two years, and apply fully decomposed farmyard manure or compound fertilizer as base fertilizer in the field, and the amount of application is 667m 2 Apply 2000kg of farmyard manure or 10kg of compound fertilizer, apply base fertilizer, then plow and rake twice to level off, and make a furrow with a height of 15-20cm and a width of 1m.

[0032] sowing

[0033] Choose to sow from early September to early October. Before sowing, spread the seeds in the sun for 3 to 5 days to sterilize the seeds and break dormancy. To the furrow surface, the dosage is every 667m 2 Use 0.8kg of shepherd's purse seeds and 10kg of fine sand, and after sowing, use fine san...

Abstract

The invention discloses a method for planting shepherd's purse as a raw material for quick-freezing processing, which comprises the steps of selecting land for furrowing, sowing, managing fertilizer and water, spraying chlormequat, spraying foliar fertilizer, pest control and harvesting. By optimizing the planting methods, we can effectively prevent and control the bolting of shepherd's purse, increase the nutritional content and flavor substances of shepherd's purse, and at the same time improve the hardness and yield, and provide qualified raw materials for quick-freezing processing of shepherd's purse.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, and in particular relates to a planting method of shepherd's purse as a raw material for quick-freezing processing. Background technique [0002] Shepherd's purse is a cruciferous herb and a treasure among wild vegetables. It combines nutrition and health care with a unique flavor, tender and delicious. In recent years, quick-frozen shepherd's purse can better maintain the color, flavor, nutrition, etc. of fresh shepherd's purse. Long, easy to eat, hygienic and reliable, the market share is increasing. [0003] The germinated seeds or seedlings of shepherd's purse can undergo vernalization after 10-20 days at a low temperature of 2-5°C, and are easy to bolt and bloom under 12h light and a temperature of about 12°C. Shepherd's purse for quick-frozen processing is most suitable for open-field cultivation in early September to early October in autumn. The quality is good, but it is very ...
