High-yielding cultivation techniques of Japanese jack bean

Japan's large-bodied tempeh is thick, with large grains, good flavor, and high nutritional value. It is popular among consumers in the market. At present, there are few cultivated areas in all regions, and there are fewer introductions on high-yield cultivation techniques for jack bean. After trial planting in Changyi City Agricultural Science and Technology Park, we have accumulated some experience. Now we introduce key technologies as follows.

1. Sowing Seedlings The large bean seeds are provided by Sato Plant Co., Ltd. and are divided into two types, white and red. The daytime temperature is around 15°C, and the night temperature can be sown at about 10°C and harvested in mid-November. In Changyi, sowing time is generally in mid-April. Before sowing, the mulberry is finely squashed and flattened into a soft state. Wet the ground until the soil is slightly dry and wet. Seed sowing 1-2 seeds per hole and seed buds Sing to the next grain, then cover fine soil 1 - 1.5 centimeters, so as to moisturize and raise the ground temperature before the film is sown. If it is grown too deeply, the seeds will rot due to lack of oxygen, resulting in lack of seedlings. If the use of nutritional breeding, such as the length of 3-4 true leaves when transplanting the best, spacing 1 meter, spacing of 0.5 meters, scaffolding cultivation, planting 1300 per 667 square meters.

2. Fertilizer and water management 5000 kg of fertilizer per 667 square meters, 50 ternary compound fertilizer, 50 kg of calcium magnesium phosphate, 25 kg of potassium sulfate fertilizer. After planting bean sprouts, the seedlings should be strictly controlled before they reach the flowering stage. This will prevent the shoots from growing too long and cause the falling flowers to fall out and phlegm. The seedlings should be placed in the cultivator and the seedlings should be transplanted in time. Do not water too much too much when the bean is in full bloom. When you are sitting in a small pot, you can increase the amount of watering and fertilizer, and top up 30 kg of potassium sulfate compound fertilizer per 667 square meters. Top dressing is performed twice. After the beans have been climbed on the racks, they should be frequently tossed to ensure ventilation and light transmission.

2, chemical adjustment beans growth strong, spread wang, in order to avoid only long vines do not take this situation, in addition to timely picking heart, but also in the flowering spray 70x10-6 naphthalene acetic acid and borax, as the case spray a certain concentration Paclobutrazol controls madness.

4. Disease Prevention and Control The major diseases of jack bean include rust and epidemic diseases. There are soybean meal and red spider in pests. In the whole growing season, thiophanate-methyl can be sprayed twice 800 times and abamectin 1500 times. Carbofuran is applied before sowing to prevent underground pests.
