[Objective] According to the low water and fertilizer use efficiency in the protected vegetable production
the influences of different fertigation treatments on the dry matter accumulation and nutrient absorption of greenhouse pepper were researched to provide scientific evidence for pepper sustainable production in Gansu Province.[Methods] Field testing was conducted. In which
normal furrow fertilizing was used as control (T1)
fertigation technology (T2) was carried out to demonstrate its influence on dry matter accumulation and nutrients absorption of Long Pepper No.3 in a solar greenhouse.[Results] (1) Fertigation technology can promote pepper plant's dry matter accumulation significantly
dry matter accumulation increased by 9.21%
dry matter accumulations in fruits and roots increased by 22.47% and 7.29%. The first dry matter equilibrium was advanced by 30 days than normal
while 2nd equilibrium stage was postponed about 41 days. (2) In treatment T2
the absorption accumulations of N
P2O5
K2O increased by 18.23%
30.73%
19.76%
and the N
P2O5
K2O proportion of fruits increased by 9.73%
13.70%
and 13.00% respectively than the ones of treatment T1. (3) In comparison with the ones in T1
the N
P
K use efficiencies of treatment T2 increased 51%
43.3%
71.2% respectively. Furthermore
the treatment T2 can save 48.9% water
increase 22.1% yield
and increase 3.55×104 yuan/hm2 income than treatment T1.[Conclusion] Fertigation technology can increase the dry matter and nutrients accumulation in pepper
and can increase the allocation proportion of them in fruits.
