When will radish be pulled out in autumn?

165438+ October is the radish harvest season.

Generally, the suitable harvest time is after the fleshy roots are fully expanded, which leads to premature harvest and low yield; If it is too late, it is easy to freeze or husk and extract, which will reduce the quality. If it is a variety with fleshy roots exposed on the ground, it should be harvested in time before the first frost to avoid freezing. If the fleshy roots are all in the soil, it can be harvested late and the yield can be increased.

Radish yield is generally 3500-4000 kg per mu for large-scale autumn and winter radishes, more than 5000 kg for high-yield radishes and 2500-3000 kg for medium-sized radishes; Yield per mu of spring radish and summer radish 1000- 1500 kg; The yield of radish in four seasons is 600- 1000 kg per mu. ?

Extended data:

The best radish is sandy loam, with deep soil layer, loose soil, rich water and good water and fertilizer conservation. The suitable pH value of soil is 5.3-7.

Radish absorbs most nutrients, followed by nitrogen and phosphorus. According to the research, for every 1000 kg of radish, about 5.55 kg of nitrogen, 2.6 kg of phosphorus and 6.37 kg of potassium are absorbed, with the ratio of 2. 1: 1:2.5.

The growth of radish needs sufficient sunshine, strong plants, strong photosynthesis, more material accumulation, rapid expansion of fleshy roots and high yield. The photoperiod effect of radish belongs to long-day plants. Under the conditions of long sunshine (12 hours or more) and high temperature, flower bud differentiation and flower branch germination are faster.
