Three-dimensional cultivation of summer garlic seedlings in summer corn

First, the selection of improved varieties of summer corn should use high-yield lodging resistance, flat leaf varieties. Such as Lu Yu No. 4, etc.; autumn cowpea selection of heat-resistant, good commercial good harvest No. 1, Qiu Kang No. 6, etc.; garlic selection of high-yield disease-resistant, dormant period short Jinxiang white garlic. Second, garlic processing garlic before planting 2 to 3 days, with 1 mg / kg gibberellin soaked for 12 to 24 hours to break the dormancy, promote germination, and then remove and place 1 to 2 days, with a knife to dig out the garlic below Stem plate, and keep the garlic head intact, in order to facilitate sowing. Third, the appropriate sowing, planting a reasonable close planting corn before June 15 to complete the size of the planting. Large row spacing 100 cm, small row spacing 30 cm, plant spacing 20 to 25 cm, autumn cowpea and summer corn with the same hole sowing, seedlings and seedlings as early as possible, leaving a strong seedlings. In the middle and late July, the corn grows to a small bell-mouth period, and rows of garlic are planted in rows of 50 cm wide. The gaps between the garlic heads are filled with loose garlic cloves and covered with 3 to 5 centimeters of fine sandy soil to facilitate the maintenance. Moisture. Fourth, to strengthen the field management 1. Intertillage weeding: In the corn trumpet mouth before the cultivator 2 to 3 times to eradicate weeds. 2. Dressing and watering: topdressing one time each time in the period of corn trumpet and large bellmouth, and 15 kg of urea every 1/15 hectare (1 acre); during the growth of garlic seedlings, every 2 to 4 days The water poured into the pot is cooled, and the ammonium bicarbonate is applied topped with water. It is 10 to 15 kg per 1/15 hectare. After the garlic has been harvested for 2 torr, it is promptly sprayed with 15 to 20 mg/kg of gibberellic acid to promote its regeneration. Generally, it can be harvested. 3 inches. 3. The preserved flower of kidney bean: The high temperature in summer will affect the pollination, resulting in falling flowers. Therefore, we must pay attention to water cooling, timely harvest. 500 mg/kg Î±-naphthylacetate can also be sprayed to protect the skin.
