Fertilization Effect On Okra Growth,Yield And Quality

Okra vegetables characteristics of the test materials, i n basal as control (CK), using two kinds of foliar fertilizer (Dr. Lu, monopotassium phosphate) and one kind of fertilizer (N:P:K= 15:15:15 fertilizer) to carry pot experiment, respectively set up three levels, a total of 10 processing, mainly studies the foliar fertilizer Dr Lu and monopotassium phosphate and compound fertilizer on the growth, yield and quality of okra. This experiment mainly test result is as follows:Okra fertilization on plant height, stem diameter, leaf length, leaf width and fruit length and diameter width obviously promote. Wherein the spraying formulation A2, B1 and C2 administered formulations promote the height of the most obvious; spray Formulations A3, B3 and formulation administered formulation C1 of stem diameter growth effect is more obvious; Okra leaf length and leaf width in the initial stage of growth, growth changes evident in the results of the growth stops. Among them, the formula A3, A2, B3, C1 are conducive to the growth of Okra leaf length and leaf width; Okra pods of fruit length and width with increasing diameter of picking and growth. Wherein the spraying formulation A1 and A3, monopotassium phosphate and administered formulation C3 increase its most obvious effect.Fertilizer production plant for okra, cell yield, plant weight, fruit weight had significant role in promoting. Spray Formulations A2 to yield per plant, the number of cell yield and fruit yield maximum. In the fruit weight, administration of formulations C1 and spraying formulations A2, B2 yield more apparent. A2 spray formulations can significantly improve the yield of Okra, administered formulation C2 and C3 suppressing an increase in production.Okra pods in N element and P element content increased with the increase of harvest, and K content with the increase of the reduced harvest, spraying formulations A2, B1 could improve its content, application of fertilizer is more conducive to nutrition accumulation of elements; okra pods are rich in rich in trace elements. Wherein the content of calcium, magnesium, manganese increases as the harvest period is reduced, iron and selenium increases picking increases. Spray Formulations B1 increased calcium content; spraying formulation B3 and C3 administered formulation increased the magnesium content; spraying Dr. Lu could increase the iron content; spraying formulations A1 and C1 will help improve the administration of formulations of manganese; selenium is a rare element, okra is rich in a lot of selenium, spraying formulation B3 and C3 administered formulation of selenium accumulation has a positive effect; changes okra pods fructose is not obvious,spraying formulation A1 effectively increase the fructose content. With the increase of soluble sugar content of the reduced harvest, spraying formulations A1, B3 and reduce post-administration pod recipes C3 consequences of soluble sugar content increases as the number of days of picking first increase; Flavonoids are an important index of the quality of okra, with the increase in pod picking flavonoid content decreased, spraying formulations A2, A3, B3 and C3 to improve the administration of the formulation pods Flavoniods more effective and flavonoid with picking the first increase after increase decrease flavonoids in pods of up to 65.12 mg·g-1FW; spray formulations A1,B1, B2 and C2 will help improve the administration of formulations of Vc pod content. Changes okra pods in cellulose content increases picking increases, spraying formulations A2, B2 and compound fertilizer effectively inhibited the content after 4 days to spend six days after flower pods in cellulose.By above knowable, different fertilization yield, quality and growth of okra is differ, the effects of spraying monopotassium phosphate is advantageous to the okra plant growth; Spraying formula A2 can promote the production of okra increase; After the blossom period, spraying formula B3 can improve the quality of okra pods, six days after flower picked okra fiber content is low, good taste, high nutritional value, is the best period of edible picking.
