October vegetable cultivation management and pest control points
Energy-saving solar greenhouse overwintering 茬 vegetable cultivation In the solar greenhouse where more than five years of wintering, cucumber, tomato, sweet pepper and other crops are planted, the phenomenon of dead seedlings during colonization to slow seedling is more common, because the applied organic fertilizer is not fully cooked. The amount of one-time application is too large, coupled with the use of rotary tillage for many years to turn the ground, the soil layer is shallow, coupled with the application of a large amount of fertilizer, so that the fertilizer is too concentrated, the fertilizer applied after the water is sprayed to dissolve And secondary fermentation, the phenomenon of root burning occurred, resulting in colonized seedlings that died at the base of the stem. It is recommended that the organic fertilizer and chemical fertilizer be applied to the soil 15 to 20 days before planting, and then ridges, watering, and soil mulching to fully ferment the fertilizer. In the middle and late October, the wintering cucumbers, cilantro and tomatoes were planted, and 4 to 6 leaves of physiological seedling age were planted in time. When planting, do not flood the water with water. First, pour the small ditch for 3 to 5 days. After the seedling has been slowed down, choose the other day to pour the ditch to meet the water requirement during the slow seedling period. Spray before planting or before watering to prevent the occurrence of diseases such as downy mildew, squatting, and stem-based rot.
Second, delaying the cultivation and management of vegetables to delay the cucumber, sorghum, and tomatoes into the fruit expansion period, timely topdressing and promoting growth, applying 15 to 20 kg of diammonium phosphate per acre with water. For greenhouses with old sheds, it is necessary to change the weather in the mid-October in the middle of October and change the light to increase the output. The temperature management of vegetables cultivated in various protected areas should be mastered at 24 to 28 ° C during the day and 12 to 16 ° C during the night. When the outside temperature drops below 10 °C, close the vents in time. When the outside temperature drops to 8 ~ 10 ° C, increase the grasshopper in time, so that the morning temperature in the shed is controlled above 12 ° C to ensure the normal growth of the crop to improve the production in the middle and late.
Third, in the open field cabbage, radish, eggplant, celery and other crops in the management of fertilizer and water, it is necessary to spray drugs to prevent downy mildew, soft rot, leaf spot and whitefly, aphids, beet armyworm and other pests. In the middle and late ten days, according to the weather changes, the cold-proof work is done. First, the anti-freezing water is poured. Second, the slight coverage can effectively extend the crop growth period.
Fourth, pest control cucumber, Chinese cabbage downy mildew spray 72% of the Best 800 times plus Yunda 120 or harvest 1500 times, 50% Anke 1500 times plus 80% Yunsheng 800 times, 5 to 7 days, Spray 2 to 3 times. Melon powdery mildew is sprayed with 5% Cui Li 1500 times liquid or 50% Cuibei spray 5000 ~ 7000 times liquid, or 30% ether oxystrobin 3000 times liquid, alternately sprayed 1 or 2 times. For whitefly, spotted fly, aphid, spray 32.5% to 1000-1500 times liquid or 1.8% avermectin 1500 times liquid, 5% flat 螨1500~2000 times liquid for various mites, Blue worm, cotton bollworm, diamondback moth, etc., can be divided into 10% 1500 ~ 2000 times liquid or Yi Fu 1000 ~ 1500 times, 10 ~ 15 days spray once, even spray 2 times, can effectively prevent various pests.
In addition, the varieties that were planted at the beginning or the beginning of this month include wintering cucumbers, bitter gourds, cold-tolerant spinach (Danish, Cold Green, Reiter 508 Tokyo Green, etc.), moss, and alfalfa. Planting impotence or simple winter stalks of green garlic (garlic) in the middle and late.
