Lily rotten seed heavy winter tube
At present, the bad seed rate of lily is 9.4% to 14.7%, and it is more than 40%. It affects the whole seedling of lily in the coming year. There are many reasons for bad species of lilies. In order to ensure the quality of lily planting in the coming year, farmers' friends should pay attention to inspections and strengthen winter training. Preventing drought and drought This year, the drought time is long, and it is necessary to prevent the impact of continuous rain in the winter on the lily. For example, soil waterlogging and oxygen deficiency are not only unfavorable to the rooting of lily and differentiation of bulblets in the ground, but also lead to disease stems and rot of lily plants. Therefore, if there is rainy weather, it is necessary to pay attention to deepening the drainage ditch so that the drainage will be smooth and there will be no accumulation of water in the fields after heavy rain. Excessive drought in winter can cause the bulbs to shrink and atrophy, affecting underground growth, and can be flooded with furrow irrigation. The water is usually poured until the depth of the ditch is about 1/3, allowing the water to penetrate the wet soil through the ditch, and drain immediately after about 2 hours. Loose weeding In the months of November and December, we took in sunny cultivating tillage, especially after a long period of time to prevent soil compaction, enhance soil aeration, and create an environment conducive to underground growth. Pay attention to weed control. In general, there is no coverage of lily lands, and no crops are grown in between, and weeds are easily weeded. Before the end of February, we can choose sunny days for the more serious weeds, and use 10% glyphosate 750-1000g plus moderate amount of 2,4-d to spray about 60kg of water. Mu can also be used 20% grams of traces of water 150 ~ 200 ml of water 60 kg, uniform spray control. Covering fertilizer cultivation before the advent of severe cold, mu with decomposed or semi-rotten cattle cattle manure 2500 ~ 3000 kilograms, spread evenly on the surface. For example, adding 50 tons of cooked cake fat or more than 75 kg of plant ash is better. In order to prevent the fertilizer in the surface of the sun and rain caused by evaporation or loss of nutrients, after fertilization can cover a thin layer of soil, can cover the fertilizer, should not cover the soil too thick. The basal fertilizer can be adequately applied to the lily field, but it can also be replaced with straw-covered insulation. After sowing, the rice can be covered with straw when the soil is dry or not wet, so that the soil temperature can be lowered in the high temperature weather in the autumn to break the dormancy of the seed bulb, promote early differentiation of the bulb and early bulbar bulbs, and prevent the bulb from rot. To weed and prevent the effect of soil compaction. However, most of the lilies sowed in autumn this year are not covered with straw. Therefore, straw can be covered when the soil is dry or not wet. Covering the straw requires no disease, and the general mu is about 400 kg of dry straw. Cover straw should be carried out when there is no wind and before the rain, cover the sides first and connect them end to end. No straw can also be replaced with other crop straws. After emergence, the straw that will affect the emergence of the lily will be gently opened by hand, and the covered straw will be removed when the line is closed after the second year of emergence.
