Planting method of selenium-rich Siraitia grosvenorii

Abstract

The invention discloses a planting method of selenium-rich Siraitia grosvenorii. The method comprises steps as follows: applying of a selenium-containing base fertilizer during planting: the base fertilizer comprises materials in parts by weight as follows: 70-80 parts of pig / cattle / sheep manure, 15-20 parts of peanuts or bran cakes of other oil crops and 2-8 parts of selenium ore powder; 0.8-1.2 kg of the base fertilizer is applied for each plant one week before planting; applying and selenium-containing topdressing in the flowering period and the fruit expanding period: the fertilizer is applied twice, the fertilizer is applied in the flowering period and the fruit expanding period for the first time and applied again 15-20 days later after the first time of applying; for each mu of soil, 100 g of a water soluble fertilizer containing 1.0%-2.0% of microelement selenium is mixed with 60 kg of water each time, and a liquid is prepared and sprayed to stems, leaves, flowers and fruits of Siraitia grosvenorii uniformly. With the application of the fertilizer applying amount and the fertilizer application method, selenium is absorbed and utilized by the Siraitia grosvenorii, the microelement selenium can be changed from the inorganic state to the organic state, and the selenium content of the Siraitia grosvenorii is remarkably increased and reaches 1-2 mg / kg.
