Yang Shulin mustard vegetable technology


In the fall and winter season, planting mustard in the Yanglin deciduous period scientifically utilizes land and sunlight resources to increase the survival rate of mustard and obtain good economic benefits. Inside and outside the forest (including elevations above 30 points), poplar forests can receive 1,000 yuan per mu for forest trees, 1,500 yuan per mu for mustard, 2,500 yuan per mu for pure yield, and Yi Yang Linlin within and outside the bay (including elevations above 36 points). Or forestry cutting, forestry income 1,000 yuan / mu, mustard 1500 yuan / mu, plus cotton (melon) 1,000 yuan / mu, mu average annual income of more than 3,500 yuan. The technical measures of this forest vegetable model are as follows:

First, choose round-leaved heart-shaped mustard varieties. In 2005, we planted round-leaved, heart-shaped, high-yield mustard varieties in forests with an average yield of 7,100 kilograms per mu, and the entire cocoon was neat, the pests were mild, and the quality was good. Therefore, it was better to select round-leaved heart-shaped mustard varieties.

Second, nurture strong seedlings. Cultivating strong seedlings is an important foundation for the production of mustard. Seedbed under the premise of applying soil and fertilizer, Mushi ammonium bicarbonate 35-40 kg tillage, according to the box width of 1.5 meters in a good place, in early September by 50 acres of seed per acre even field seeding, after sowing with 50 kg per acre Phosphorus fertilizer mix appropriate amount of fire and soil ash as cover seed fertilizer, and fill the ditch with water, soak the soil, and then blow out the bright water, spray the liquid solution after emergence, and prevent the damage of locusts and foliar insects, weeding and removing impurities. The seedlings are timely and appropriate to raise the seedlings. The transplants are made to stay large and small, followed by classification, and a good adherence of phosphorus roots is planted to ensure that the field is well-matched, strong, and stable.

Third, rational dense planting. The leaves in the middle and early leaves of mustard leaves must be slightly flattened, and paclobutrazol must be adjusted before twigs are harvested before accelerating the leaf shrinkage center. However, the whole growth process needs reasonable space, and the specific conditions such as soil quality and soil strength should be met according to the requirements of high yield. Closely planted. It is advisable that the distance between the plants is not less than 33 cm and the row spacing is not more than 46 cm.

Fourth, the amount of fertilizer. Mustard needs a large amount of fertilizer. According to the yield of more than 6,000 kilograms per mu, it must be a good "three levels." The first is base fertilizer clearance. Before application of ammonium bicarbonate, 60 kg of ammonium bicarbonate and 75 kg of phosphate fertilizer should be applied before field tillage. The application must be deep and uniform so as not to cause damage to the transplanted seedlings. The heavy-soil phosphorus fertilizer can also be used as surface fertilizer. The second is the growth of mustard seedlings at seedling stage, 8-10 kilograms of urea per mu, plus 5 kg of potash fertilizer. The classification is divided into two topdressing stages. The seedling stage differs in the seedling stage, and 50-60 kg of ammonium bicarbonate can be applied per acre to carry out acupuncture at the acupuncture point. Deeply. The third is to reapply stout handles, thick leaves and young manures. This is the mature stage of growth of mustard. It is necessary to ensure the use of large-scale fertilizer and large-scale fertilizer. The specific application is to mix 10 kg of urea and 5 kg of potassium fertilizer per acre for 40 days before harvest. Mustard will grow in all directions.

Fifth, scientific regulation. The vegetative growth of Brassica juncea enters a vigorous period. After the formation of a high yield, about 15 days before harvest, 15 to 20 grams of 15% paclobutrazol plus trace amounts of urea and an appropriate amount of potassium dihydrogen phosphate are sprayed on each acre, before harvesting. About 20 days, depending on mustard growth, 20-30 grams of 15% paclobutrazol was sprayed in the same way.

Six, timely harvest. The quality of mustard is closely related to the harvest sooner or later. Mustard from about 180 days from sowing to harvesting. Due to the influence of temperature and water and fertilizer conditions in the field, the maturity period is almost a week or so different. The best harvest period must be mastered. If the planting area is large and the labor force is tight, the mustard must be grown. Cubs begin harvesting when they are 7-10 cm in size; if the area is small, they can be harvested when they are 13-16 cm. If the harvest is too early, the output will be lost. If the harvest is too late, convulsions and fresh food will appear, affecting the mustard quality.
