French green beans, also known as French beans, are rich in syrups, proteins and fats and have a high nutritional value. It is a leguminous plant, dwarf species, straight root system, strong regenerative ability, strong plant growth, plant height 60-70 cm, main stem section number 4-5 sections, single branch effective branching 9-11, first branch Height 7～8cm, plant type upright, compact, large leaves, nearly elliptic, dark green, purple purplish, dish corolla, self-pollination, bean pods 10～15cm, 35～40èš è±† 豆 豆 豆 豆 豆 豆 豆 豆 豆 豆 . Seeds are black, seed coat is thin, germination is fast, and growth is strong. One year of spring and autumn planting two seasons, sowing to early harvest time is about 45 days, the whole growth period is about 90 days. In this article, microbial fertilizer expert Gymmare will introduce the management of its spring as follows.
1. Choosing site for spring bean planting Choose ready-to- transport plots with loose soil, deep soil layer, medium fertility, convenient irrigation and drainage, and sunny loam or sandy loam soil. Seven days before sowing, the plots were ploughed and ploughed. Before applying the decomposed organic fertilizer 1200 kg/mu before the whole planting, if the vegetable farmer wants to further improve the soil fertility and the quality of the fertilizer used by the plant, it is recommended that the vegetable growers use some microbial fertilizers such as the golden babe microbial fertilizer mixed as the base fertilizer because the microbial fertilizer The use efficiency of basal fertilizer can be increased, and the secreted auxin can promote seedling growth. Fine soil preparation, sulcus, gutters, and ditch are connected to facilitate drainage. In general, the broadband trench is 100 centimeters wide, with a width of 70 centimeters, a trench width of 40 centimeters, and a trench depth of 30 centimeters.
2. The spring bean planting sowing planting timely. When the spring sowing temperature is stable above 10°C, grab the cold-tail warmer to sow the crop. Spring sowing is generally done from late March to early April (green beans can be followed by hybrid rice autumn harvest); autumn sowing is selected in hybrid rice seedlings that have been harvested and planted from late August to early September. Both spring and autumn sowing are adopted with hybrid rice seed production for paddy-upland rotation. Seeding should be performed on seeds that are full, uniform and glossy, without cracked skin, and without pests. Seeds are sown for 1 to 2 hours before sowing. The sowing depth is 2 to 3 centimeters. Generally, 2.5 kilograms per mu are used for field planting. On the whole surface, with a spacing of 40 cm, first open two planting trenches with a furrow depth of 5 to 7 cm, and then conduct artificial on-demand seeding at a distance of 15 cm from each well, sowing two seeds per hole and sowing 8000 mu. Immediately after sowing, cover 3 to 5 cm of thick fine soil, and then water it properly to ensure that the soil is moist and smooth. Seedlings should be seeded once every 5 to 7 days after sowing, and seedlings should be replanted in a timely manner to ensure basic seedlings. Especially in autumnal plots, due to low rainfall, dry soil moisture and seedlings should be checked promptly after sowing. If the soil is too dry, it should be watered in time.
3. The main points for fertilizing the spring bean cultivation are: 1. Apply base fertilizer and apply organic fertilizer. Apply 1200 kg/mu of decomposed organic fertilizer before the whole planting. It is recommended to use self-made organic fertilizer with organic fertilizer, which will not only save the cost, but also the special organic fertilizer starter of Jinbao can thoroughly decompose the fermented material to ensure that the root is not burned. Burn the seedlings. Apply 50 kg of calcium phosphate and 50 kg/mu of compound fertilizer before sowing. Apply 1 layer of thin soil and fertilize it after sowing. The second is to raise the seedlings early, and re-apply to push flowers and strong manure. After the seedlings were used, 150 kg of excrement was used to recover the first fertilizer of ammonium bicarbonate 10 kg/mu, which promoted plant growth and flower bud differentiation. 15 to 20 days after sowing, 20 kg of ammonium bicarbonate and 10 mg/mu of superphosphate were applied to the roots of the bean plants in order to lift the seedlings. The first cultivator was used in combination with the small cultivating soil; 25 days after planting, 50 kg of compound fertilizer plus 15 kg/mu of potassium sulfate are thoroughly mixed and applied at a distance of 10 cm from the root, and then immediately watered at the root of the green beans to form a suitable mixture for the second cultivator. More robust. During the flowering and poding period, topdressing once every 7 days, mainly organic fertilizer and ammonium bicarbonate. . The third is timely and adequate top dressing. Because of the harvesting of fresh sorghum, green beans still require multiple top dressings. About 35 days after sowing, during the initial stage, one spray foliar fertilizer was applied (0.3% urea plus 0.05% ammonium molybdate plus 0.2% potassium dihydrogen phosphate); entering the bean harvest period, the first time the beans were picked After spraying, 0.2% urea, 0.1% borax, and 0.2% potassium dihydrogen phosphate were sprayed, and then sprayed once every other week until harvesting beans.
4. The control of green bean diseases and insect pests in spring is mainly due to processing exports. Therefore, in the prevention and control of pests and diseases, pesticides should be used in accordance with the export standards of agricultural products. Bio-pesticides and pesticides with high efficiency, low toxicity, low residue and long control period should be used. the Lord. In the flowering and fruiting stage, pesticides are no longer used. The seedling stage focuses on the control of aphids. During the growth period, attention is paid to the prevention and control of pests such as Spodoptera litura and can be controlled by using pesticides such as fast killing spirit and high-fenvalerate esters. The diseases are mainly root rot and downy mildew, 70% methyl bacillus to prevent root rot, and thiophanate methyl to control downy mildew.
