Fujin: the benefit of "garlic with beans" is high.

Interplanting soybean with garlic is one of the conservation-saving agricultural cultivation models currently popularized by Fujin Agricultural Technology extension Center. it forms a symbiotic relationship that promotes each other according to the growth law and habits of crops. that is, the nitrogen fixation of soybean rhizobium increases the nitrogen content of soil, so that garlic is not de-fertilized, which is beneficial to the later growth and expansion of garlic. The plant of garlic, especially the root of garlic, has a strong spicy taste in the soil, and has a strong inhibitory and killing effect on various pests, viruses and bacteria of soybean. Therefore, growing soybeans in garlic field does not need all kinds of pesticides and herbicides, which is an important way to produce green food.

Autumn soil preparation and autumn fertilization cultivation of garlic must be carried out in autumn soil preparation, suitable tillage period deep turn 25-28 cm, combined with soil preparation per mu application of organic fertilizer 3-4 cubic meters, rake fine fishing flat. For example, if there is a drought in autumn, suppress and conserve soil moisture.

After planting garlic after Qingming, when the soil freezes 15 to 20 centimeters, you can plant garlic; after planting, it will freeze at night and will not cause freezing damage to the garlic cloves. The method is as follows: the depth of the ditch is 5-7 cm, the ridge distance is 60-65 cm, seed fertilizer is spread along the ridge, and 20 kg of multi-compound fertilizer is applied per mu. After fertilization, the original V-shaped ditch is beaten into a U-shaped furrow with a pick, with a width of 15 cm to 18 cm, a depth of 3 cm and a distance of 9 cm to 11 cm. The planting must be shallow, and the garlic tip should not be exposed after covering the soil. Do not plant, must spread evenly, do not leak, do not gather pile, sow as far as possible on the edge of ridges and furrows, sowing amount is more than planting, need to thinning seedlings, inter-seedlings, covering 2 cm to 3 cm. Ridging can be carried out after sowing, which has the advantages of increasing ground temperature and early emergence of seedlings, but one more field operation is not good, and it is easy to cover the soil too deep. It is also possible to avoid ridging and should be used flexibly.

When the first leaf of garlic seedlings is unfolded, a plough is carried out in front of the shovel to loosen the soil, raise the soil temperature, and promote the garlic seedlings to take root quickly and deeply. Shoveling and weeding the two leaves together to eliminate the weeds on the seedling eyes and ridges, it is not necessary to carry out seedling thinning and seedling thinning, but the principle is to pull out the small and stay the big, pull out the inside and outside, fix the seedlings according to the number of seedlings required reasonably, and ridge after the seedlings are fixed.

After sowing soybean the Beginning of Summer and before Lesser Fullness of Grain, garlic seedlings grew to 25cm high. Soybeans were planted in ditches and 15 kilograms of Hefei or special soybean fertilizer were applied per mu. After sowing, the soil was compacted.

When shoveling weeding bean seedlings with two needles, all the weeds on the surface are unearthed, which should be removed early, small and completely. In particular, it is pointed out that at this time is the bean and garlic symbiotic "four ridges" state, unfavorable operation, should choose a small hoe board, can not produce injured garlic roots, to avoid the expansion period of garlic horizontal crack.

When the garlic moss is straightened together with the garlic leaf, the best harvest time is when the garlic moss is about 10 cm higher than the top leaf, which affects the yield of garlic moss prematurely, affects the quality of garlic moss too late, and is not easy to pull out after aging. It is best to pull out garlic moss at noon on a sunny day, and the extracted garlic moss is long and uninterrupted. in order to make the product neat and consistent, you can use a toothpick to tie the garlic moss stem 10-15 cm from the ground, and the pulled garlic moss can be disconnected from the hole, which can increase the yield. The garlic moss in Heilongjiang Province consists of 2/3 outside the leaf sheath and 1/3 inside the leaf sheath. The experimental results show that the garlic moss is larger and the yield is higher than that of unpulled garlic. By pulling out the garlic moss, it not only increases the income, but also plays the role of controlling the upper and lower levels.

After the garlic was bolted, the garlic began to expand and split. If the soil is too deep and the soil is hardened, it will affect the expansion of garlic. At this time, it is necessary to remove too much covered soil and cultivate it at the bean root, killing two birds with one stone. Generally speaking, 1/3 to half of the garlic is exposed to the surface. Don't hurt the roots or touch the garlic.

Harvest garlic when most of the garlic leaves turn yellow, the garlic moss becomes soft, and the garlic clove foreskin hardens and begins to be harvested. Pulled up along the ridge, bundled into small bundles out of the field to dry, can be head up, leaves down, flat to dry; or head out, leaves facing north and south direction palletizing to dry, to garlic flying soft skin, garlic leaves half-dry braided. 50 braids, two braids hang, put on the wooden frame in the air. After the garlic stem is dry, store it in a ventilated and dry place.

Soybeans ploughing soil and topdressing garlic after harvest, topdressing can be carried out if the bean seedlings have symptoms of de-fertilizing. After topdressing, deep ploughing is used to cultivate soil, and large ploughshares are used to carry more soil to form "meeting ridges". The deep ridges and high ridges are beneficial to drought resistance and drainage. The foliar topdressing of soybean in the early and middle stages of flowering can be sprayed with 0.3% ammonium molybdate plus 0.2% potassium dihydrogen phosphate, or 0.5% urea plus 0.2% potassium dihydrogen phosphate for 1 or 2 times.

Diseases and insect pests and soybean harvest garlic beans basically no diseases and insect pests, generally do not need to control, but special disaster years should also pay attention to observation and prevention. Soybean harvest is the same as other planting methods.
