Abstract


Northwest Hebei sandy chestnut soil farmland soil shallow, poor soils, uneven distribution of precipitation during the crop growing period, the agricultural production in the region is low and unstable, inefficient. Sparse economic crops Gift watermelon has the accounting days is not an area of ??resource utilization characteristics. Sandy chestnut soil in more than 2/3 of this study to the region accounted arable land for soil material for the test to gift a small watermelon study ditch membrane planting mode Ridge, different irrigation with mulching on gifts small watermelon the yield, quality and water use efficiency. The main findings are: (1) under different irrigation processing conditions, the two varieties of watermelon are three Irrigation (W3, before sowing the water stretched vine water swelling melon water) deal with the highest economic yield, film processing yield of 20077.74 and 20309.33 kg · hm -2 ; the albuginea processing yield were 23708.74 and 23982.22kg · hm -2 ; the black film processing yields, respectively to 23,817.73 and 24093.63kg, · hm -2 . Compared with the corresponding (W1, before sowing, irrigation water) processing time increased by 26.65% and 18.62%; 29.30% and 21.55%; 26.07% and 17.98%, respectively. (2) different irrigation with mulching two varieties of watermelon W3 appearance quality the best, for a long time a deal with an average increase of 7.69%; luck to edible edible part W3 processing than W1 W3 treatments than W1 processing The average increase of 4.94%. Two varieties of watermelon nutritional quality indicator parameters than W1 processing have improved to varying degrees, for a long time a fruit center soluble solids content the The W3 processing than W1 processing increased by an average of 11.96%; soluble solids content of for a long time a fruit edge, W3 processing than W1 processing increased by an average of 21.35%; Hisakazu fruit soluble sugar content, W3 processing than W1 handle an average of 20.48%. Good luck to the fruit center of soluble solids content The W3 processing than W1 processing increased by an average of 11.91%; luck to fruit edge of soluble solids content the W3 processing than W1 processing an average increase of 8.90%; luck to fruit soluble sugar content, W3 processing, than W1 processing increased by an average of 17.81%. (3) in the whole growth period, two varieties of watermelon irrigation treatment 0 6 0cm Water capacity expansion Guaqi are significantly reduced. Two varieties of watermelon the stretched Man - fruit enlargement of the highest water consumption, albuginea handle long stretched it out vine stage - the stage of fruit enlargement consumption intensity, an average of 5.13mm · d -1 ; albuginea deal with the good fortune to stretch the vine - fruit enlargement period consumption intensity average 5.40mm · d -1 . Two varieties of watermelon water use efficiency (4) different irrigation, film processing are W3F2 treatment was the highest, W3AF2 up to 97.70kg · mm -1 · hm -2 than W1AF2 increased by 27.84%. W3BF2 up to 98.84kg · mm -1 · hm -2 19.64% than W1BF2 improve.
