Abstract

Research results of some technical measures of the production of cantaloupe Taki variety growing in the tunel house with plastic cover. The experiment was laid out as Randomized complete block design (RCD), 3 treatments and 3 replicates, in Summer crop in 2019 In Queen farm, New Style Trade and Construction Joint Stock Company. Experiment 1 including 4 treatments: treatment 1: 50% coir + 40% microbiological organic fertilizer + 10% rice husks; treatment 2: 60% coir + 30% microbiological organic fertilizer + 10% rice husks ; treatment 3: 70% coir + 20% microbiological organic fertilizer + 10% rice husks; treatment 4: 80% coir + 10% microbiological organic fertilizer + 10% rice husks, Experiment 2 including 3 treatments: treatment 1: density: 350 plant/m2; treatment 2: density: 530 plant/m2; treatment 3: density: 700 plant/m2. Experiment 3 including 4 treatments : Treatment 1: super phosphate fertilizer and , nutritional concentration 5%; Treatment 2: Nitrogenous fertilizer + super phosphate fertilizer (ration 1:1), nutritional concentration 5%; Treatment 3: fertilizer N:P:K: 13:13:13-TE, nutritional concentration 5%; Treatment 4: nutritional concentration 0%. The results of researching some technical measures to produce cantaloupe Taki seedlings have selected the production process of Taki melon seedlings as follows: The mixing substrate (70% alluvial soil + 20% organic microorganisms + 10% rice husks); The sowing density of 350 plants/m2 (tray of 50 plants / tray); Nutritional supplement with fertilizer N: P: K (13 + 13 + 13 + TE) mixed with a watering concentration of 5% for Taki melon seedlings to grow well.
