A kind of method of radish seed plant cultivation

Abstract

The invention discloses a Raphanus sativus L. seed plant cultivation method. The method comprises the following steps that (1) fermented rice husks are prepared; (2) fertilization and soil working arecarried out on a seed plant nursery garden according to normal requirements, and seed plant holes are dug and aired for at least one week; Raphanus sativus L. seed plants are pulled out of a materialgarden in sunny day, and are aired in the holes for one day, and attention is paid to antibreezing at night; ; (4) seed plant field planting soil is prepared; (5) the seed plant holes are filled withthe seed plant field planting soil prepared in the step (4), and covered with field soil to prevent the seed plants from lodging; and (6) watering is carried out after field planting with multiple times and small amount in each time, and the seed plants are managed normally after survival. According to the method, the disease rate of Raphanus sativus L. seed plant cultivation across Winter in themiddle and lower reaches of Yangtze river can be reduced, the problem that the Raphanus sativus L. seed plant tends to be damaged and easy to be infected with bacteria in the transplanting and filedplanting process and seed cultivation is influenced can be solved, the characteristics of low weak retention and high air permeability of the rice husks are used, fermentation is realized via EM inocula, the rice husks are used together with coconut bran, invasion caused by harmful bacteria can be inhibited, use of pesticides is reduced, and smooth cultivation of Raphanus sativus L. is ensured.

Description

technical field [0001] The invention belongs to the field of radish breeding, and in particular relates to a high-efficiency cultivation method for transplanting radish seed plants. Background technique [0002] Radish (Raphanus sativus L.), also known as radish and calabash, is an important vegetable of the genus Radish in the family Brassicaceae. Radishes need to undergo low-temperature vernalization to bloom. Therefore, radish breeding in the middle and lower reaches of the Yangtze River needs to be planted in autumn every year. After they grow up, the seed plants are selected for transplanting. Before transplanting, most of the leaves should be cut off, and only the base of the stem should be kept. growth point. Some radish roots are too long and too large, and they need to be cut off before they can be planted in the plant nursery. Therefore, the radish plants are seriously damaged during transplanting, with many wounds and are susceptible to infection by various patho...

Problems solved by technology

With the increase of extreme abnormal weather, in mid-winter, when the weather is clear, the daytime temperature in the greenhouse will rise significantly again. This kind of frost for several months occasionally alternates with high temperature and accompanied by high humidity in the greenhouse environment, which causes the occurrence of radish seed plant diseases to be accidental. , suddenly, and the radish seed plants are mainly radish roots, which are buried deep underground and rich in nutrients, so the chemical control effect is poor

[0004] The preventive measures against radish seed diseases are mainly the planting of the radish with drugs, and the disinfection of the radish by soaking the seeds, etc., but these preventive methods are short-term and unstable in effect, and a large amount of drugs damage the soil ecological environment, which is not conducive to the sustainable use of land
