Dry farming cress cultivation method

Abstract

The invention discloses a dry farming cress cultivation method. The method specifically includes the steps of 1) wetland seedling raising: selecting a lotus root field seedbed rich in organic matters, and making a lotus root field into a ridged field after harvesting; shearing mature cress scapes into stems 10-15cm in length, uniformly sowing the stems on the surface of the ridged field, and pressing the stems into mushy seedbed soil with a wood board to enable the mother stems not to expose over the soil surface; and erecting a flat canopy cover sunshade net for cooling and moisture preservation, and removing the sunshade net after sprouting; 2) planting; and 3) ridging softening: when plants grow as high as 30-40 cm, performing deep ridging for one time; and before ridging, finely drawing out soil between the lines, ridging plant edge ridge soil beside the plants to change original ridges into furrow bottoms and planting furrows into ridges, ridging for 20-30cm in height to enable seedling tips to expose over the soil surface by 5-10cm, and harvesting and marketing 20-30 days after ridging. The dry farming cress cultivation method has the advantages that new technologies of wetland seedling raising and one-time deep ridging and the like are adopted, so that time-to-market of cress is shortened, diseases are reduced, yield is improved, labor cost is lowered, and production effectiveness is improved greatly.

Description

technical field [0001] The invention relates to the field of watercress cultivation, in particular to a method for cultivating watercress in dry farming. Background technique [0002] Soil-cultured softened cress is a local characteristic vegetable in Quzhou. Cress softened by soil culture is as white as jade, soft in texture, crisp and refreshing in flavor, and has a special fragrance. Softened cress is very popular among consumers. However, there are some bottlenecks in the production of soil cultured softened cress. Mainly contain: 1, the production cost is high. Soil cultivation of softened cress requires a lot of labor, and the average labor cost for cultivating soil per mu exceeds 3,000 yuan. The production cost remains high, and labor conflicts are prominent. It is necessary to study methods and ways to save labor and labor; 2. It is difficult to keep the mother stem of cress and raise seedlings. The mother stems of cress are in the high temperature period in the ...

AI Technical Summary

Problems solved by technology

Mainly include: 1. High production cost

The production of softened cress by soil culture requires a lot of labor, and the labor cost of cultivating soil per mu exceeds 3,000 yuan. The production cost remains high, and the labor contradiction is prominent. It is necessary to study methods and ways to save labor and labor; 2. It is difficult to keep the mother stem of cress and raise seedlings

The mother stem of cress is in the high temperature period in the later stage of keeping the mother stem and the seedling raising period, and there are many diseases, so it is difficult to keep the mother stem and raise seedlings; 3. Lack of soil cultivation technology

The number of times of soil cultivation increases labor costs; the time of covering the soil is long, and adventitious roots grow from the base of the cress, which affects the appearance quality; it is difficult to topdress after soil cultivation, the growth rate of cress slows down, and the fertilizer utilization rate is low; the soil is cultivated early, and the soil temperature is high , it is easy to induce the occurrence of cress stem rot, and it is difficult to prevent and control with medicine after soil cultivation; 4. The continuous cropping obstacles of cress are serious, especially the serious stem rot

Rotten seedlings and rotten stems are common, and severe years even result in broken seedlings and no seedlings to plant, which affects the implementation of production plans and the first season's harvest; large areas of rotten stems cause substantial production reduction and economic losses

Although cress is implemented in rotation with other vegetables (dry farming), it is still difficult to solve the occurrence of stem rot
