Effects of Controlled Release Fertilizer with Different Ratio on the Substrate Nutrient, Growth, Yield and Quality of Tomato Cultured in Bags in Solar Greenhouse
As a result of the controlled release of nutrients
controlled release fertilizer (CRF)
used once
can meet the nutrient demand of field crops for more than 4 months
which can realize the efficient use of fertilizer. Now it is applied successfully in field crops. For this reason
according to the law of tomato nutrient absorption in solar greenhouse
four kinds of different CRF treatments (A
B
C
D) were established through added different quantity of controlled release urea and potassium chloride into growth-bag substrate
the paper investigated the effects of different CRF treatments on the growth-bag substrate nutrient change
and the growth
yield and quality of tomato in solar greenhouse compared with no fertilizer (CK) and conventional fertilization (CKT). The experiment results showed that with the increase of CRF dosage
tomato plants growth and yield showed a change trend of first increase and then decrease. Among all treatments
the treatment C was the best
of which the substrate EC value was stable
the nutrient content of available nitrogen
phosphorus and potassium in growth-bag substrate of treatment C became slightly lower than that at the beginning; Compared with CK
the plant height increased by 21.75%
the stem width increased by 59.46%
the biomass accumulation increased by 75.12%
the yield increased by 226.36%
and the fruit quality was much improved. Compared with CKT
little nutrient was left in the substrate and the fruit yield increased by 24.48%. The experiment result indicates that CRF could increase the nutrient use efficiency and fruit yield for substrate growth-bag of tomato in solar greenhouse.
