Brazilian upland rice is one of the precious premium varieties of Brazil's upland rice introduced in Brazil by Prime Minister Li Peng in 1992. It was piloted in Jiangxi province in China and was tested in more than 20 provinces and cities across the country in 1995-96. Already in the country to promote tens of millions of acres has achieved good economic and social benefits. In the spring of 1998, the Bureau introduced brazilian upland rice seeds and successfully tested in villages such as Lagong and Baitudeqing. The whole growth period was 120 days and the plant height was 115 cm. Two kinds of planting methods are used: First, transplanting seedlings and transplanting. Sowing in mid-March, transplanting on April 22, harvesting on July 20; Sow on April 2 and harvest in early August. Both methods were successful. The maximum yield of white clay is 250 kg. After the observation and test of the test plant, the variety has a short growth period, good resistance to pests and diseases, wide adaptability, strong drought resistance, medium tillering force, high yield, and soft rice quality rice. Delicious and other advantages. The disadvantage is that the plants are high and the cold resistance is weak and they are suitable for mulching. Promoting the cultivation of this variety is an effective way to solve the problem of eating in poor people in Dashi Mountain and food-deficient areas. Main cultivation techniques:
First, apply intensive basal finesse to prepare 20-300 mu of farmyard manure before sowing, and 70-50 kg of compound fertilizer, 80 kg of compound fertilizer, spread evenly over fields, and carry out two plowing and two plowing. To smash smashing stalks, start with 3 //FONT > 5 days before sowing, and open them up to 80 cm wide, so as to be as wide as the middle of the two. The width of the ditch is 20 cm deep and 20 cm deep. In order to prevent the underground pests from harming the seedlings, mu is sprayed with 3 kg of furanoide and 40 kg of finely mixed soil to the surface of the husk. Then the glutinous surface is sorted into fine, broken, sparse, loose, and flat. net.
Second, timely planting and strict quality control Early rice should be broadcast on March 20 or so in 1-2 days, the latest should not exceed the end of March. Mu seed amount 2.5-3 kg, according to the car quantitative, even sowing, in the face of the 57-inch holes (holes) hole depth 5 cm is appropriate, not too deep and shallow, uniform specifications, while playing side In the next step, point the seed that has been exposed to white out into the hole, with 5 holes/FONT> 6 per hole, and then cover the seed with fine soil to prevent the seed from protruding from the topsoil. Finally, cover the surface with a 100 cm wide agricultural film. Use a thin earth pressure regulator around the membrane to prevent wind blowing.
Third, strengthen field management. Pay attention to the following points
1. Observe and break the membrane in time. 3-5 days after sowing, we must walk to the field to see a look, one is to check whether the film is the same, the second is to see whether the surface of the water after the rain, the third is to check whether the seedlings exposed soil surface, If the seedling has been unearthed, it is necessary to break the membrane immediately, and use a knife or a blade to cut the membrane on the hole so that the seedling will protrude from the hole to the film surface smoothly so as to prevent the film from suddenly generating heat during the sun. Causes sprouting.
2, pay attention to do a good job chasing Miao Fei, until the seedlings have 5? / FONT> 6 leaves, it is necessary to conduct a chase Miao Fei, mu urea 3 kg, potassium 2 kg, the two fertilizers together into 10 kg The water is dissolved into fertilizer water, and in order to prevent pests from being combined, 2 potassium potassium phosphate, 2 dimethyl thiophanate or 2 carbendazim are added, and the mixture is diluted with 50 kg of fresh water for dilution. , And then spray with a sprayer, spray evenly when sprayed, everywhere sprayed, much the same, so that the seedlings growth and development of a uniform spray is best to choose cloudy or sunny after 5 pm to avoid high temperature burning seedlings.
3, pay attention not to flood the field (ground) surface, from the species to the harvest surface can not be stagnant water, a stagnant water will produce stuffy dead seedlings. Therefore, drains and drains should be made around the perimeter of the field.
4, pay attention to the prevention of pests, birds, rodents harm, to prevent the emphasis on governance, rule early treatment, do not wait until more serious and then spray, so be diligent to check the ground to observe, find problems immediately resolved, control methods Same as rice.
