5. whole climing, keep down the vines of a creeping plant

In the time of climing long 30-35 centimetre, should carry out whole climingly, straight climing reason, it is evenly distributed, and keep down the vines of a creeping plant with soil block on joint, impelling generation adventive root, fixing leaf is climing, prevent mutual shading and damaged leaf by the disconnected root of hindering of wind, press once every 5-6 joint, until cissoid covers with furrow face later;

6. artificial supplementary pollination

Melon seedling starts pollination while outputing second female flower, select to lead well-developed female flower on climing and lateral bine, and its bud handle is thick, ovary is loose, profile is normal, the light green and glossiness flower of color; At every morning 8:00-11:00, with the fresh male flower of open and positive loose powder on the same day, petal is pinched with hand to anthocaulus direction, then the stamen of male flower is aimed to the column cap of female flower, be stained with gently several lower;

7. select melon, stay melon

The climing above melon of second and third female bow structure of the master that selects and remain, every strain stays 1-2 melon to be advisable;

(6) timely collecting

Differentiate Watermelon Maturity, the firstth, calculate and sit melon number of days according to varietal character; Second sees fruit appearance, and ripe watermelon melon skin is hard, and decorative pattern is clear, the inside systolic depression of umbilical region and the base of a fruit, and on melon handle, the large portion of fine hair comes off, and the last joint tendril in joint position of bearing fruit is withered; The 3rd tin of fruit sound, with finger attack fruit listening, sending " bang, bang " low and hoarse muddy sound person is ripe melon, the vexed mute or bright ripe mistake of buzz multilist of sound, sending " thump, thump " clear and melodious sound is unripe watermelon; The 4th with feel, a hand rest melon, and melon is patted in another have gentle hands, if holder melon feel has vibration person for ripe melon to micro-; Also can be gently by handle shake in the time plucking melon, melon handle can easily not taken person and is generally ripe melon from melon is climing, according to above method synthesis judgement, timely collecting.
