Embodiment Construction

[0011] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0012] (1) The technique of moving seedlings before the sowing period and avoiding high temperature. Move the sowing period of extremely early-maturing cultivated cress forward by 20-25 days, usually in early July when the temperature is low, so that the emergence of cress can effectively avoid the highest temperature period of the year (usually mid-July-August early), to achieve safe emergence and rooting. The sowing rate per mu is 1000-1200 kg / mu. Pile the celery into a 50-60 cm high seed pile 2-3 days in advance, put it in a cool place, cover it with a thick cloth or straw curtain, and use well water to control the temperature and keep it moist For germination, the temperature is controlled at 23-28°C. Before sowing, cut the celery into 20-30 ...

Abstract

The invention relates to high-temperature-resistant extremely-early-maturing submerged cultivation technology for cress (oenanthe javanica), referring to bringing the cultivation period of cress forward to avoid the hottest seasons all year round so as to avoid death of cress seedlings or tender shoots due to hot weather during planting to further prevent sparse seedling emergence and cress seedling rot, thereby effectively solving the technical problem of poor temperature resistance in cultivation of extremely-early-maturing cress. Besides, the regeneration technique of cutting down seedlingsin due course solves the technical problem of rough taste of cress flesh and blooming of cress due to high temperature; the nutrient and water management technique can build corresponding water layers according to height of cress plants, apply fertilizer during cultivation, thereby solving the technical problems that how to improve quality of growth environment of cress and how to supply nutrition to cress in time; the growth regulation and control technique can improve inter-node extension and tenderize the cress, thereby increasing output and improving commodity.

Description

technical field [0001] The invention relates to the technical field of cress production, in particular to a high-temperature-resistant and extremely early-maturing cultivation technology for waterlogged cress. Background technique [0002] Very early-maturing cultivation of waterlogged cress generally refers to the watercress sown during the period from the end of July to the first ten days of August, which has the advantages of early market, high price and good profit. The end of July to the first ten days of August is really the hottest period of the year. The technical requirements for the safe emergence of extremely early-maturing cultivated cress and to ensure the acquisition of sufficient basic seedlings are high. Celery buds are often scalded to death, seedlings are sparse, and even large areas are rotten. Without seedlings, the output is mostly 1000-2000 kg / mu, and it is extremely unstable, and it is difficult to achieve a high yield level. Contents of the inventio...
