2. Unit corn cultivation method
Application (Patent) No.X
Abstract: The present invention discloses a unitary corn planting method. The corn planting land is divided into a number of planting units. Each planting unit is a prominent square platform. The middle part of the platform is provided with pits. The pits are filled with base fertilizer and backfilled in sequence. From the soil and manure to the pit, corn is cultivated evenly around the platform. The planting units are arranged by ridges and can also be distributed by two ridges and one ridge. The center moment of the adjacent planting unit is 130-330cm, the depth of the pit is 15-25cm, and the plant spacing of corn is 5-8cm. The planting unit is used to grow corn. The fertilizer is applied in the middle of the unit and is not easy to lose. The effect is long-lasting. Corn is planted around the ring to resist plant lodging, which is beneficial to root growth, reducing water and soil loss, increasing pollination opportunities, and increasing corn yield.
3, Summer maize seed harvest and weight increase high-yield cultivation method
Application (Patent) No. 9
Abstract: The present invention relates to a high yield corn cultivation method, belonging to the field of agronomy. According to the problems existing in the traditional wheat cultivation of corn, based on the theoretical research, the method of increasing the grain weight and high yield of the corn seeded live harvesting late harvest is proposed. The main content is the Huanghuaihai region, especially the summer corn area in Shandong Province, and the medium-late and late-maturing high-yield compact plants are selected. New maize varieties (100 to 105 days of growth period), intercropping corn in the middle and late May to the summer of June 5th to 15th after harvest; suitable for close planting, establishing a reasonable population structure, ensuring population density and uniformity, and compactness Type maize seedlings were planted at 67500 to 75000 plants/hectare, and compact large ear varieties were planted at 52500 to 60000 plants/hectares; harvested ripening, ie, wilting of leaves, black layer of grain, disappeared when the milk line disappeared, generally on September 25th. - Harvested on October 1. The application results showed that the yield of maize was increased by 15% to 20% compared with the wheat cultivation method.
4. A Breeding Method for Planting Acid Corn Varieties
Application (Patent) No. 0
Abstract: The invention discloses a breeding method of low phytic acid corn varieties, which belongs to the field of crop breeding methods. The present invention mainly uses selected maize inbred lines Qi319 with good agronomic traits and low phytic acid content to select low-phytate inbred lines through backcrossing, hybridization or tissue culture methods, and then use the cultivated low-phytic acids. Inbred lines were paired with low phytic acid hybrids. The low phytic acid corn variety with good agronomic traits and quality traits can be cultivated by the method of the present invention, so it can be popularized and applied in production; the low phytic acid corn cultivated by the method of the present invention can be exempt from the addition of phytase and dihydrogen phosphate. Calcium improves the absorption and utilization of iron, calcium, and zinc in feed, and reduces the pollution caused by the enrichment of phosphorus in the environment. To promote this corn hybrid can also increase the utilization of phosphate fertilizer in soil. It is conducive to the sustainable development of agriculture.
5. Breeding method for hybrid seed of inbred lines resistant to waxy corn by biotechnology
Application (Patent) No. 2
Abstract: The present invention relates to a method for breeding a hybrid seed resistant to waxy maize inbred lines by using biotechnology. The method is characterized in that according to the genetic law of the crop, the aphid resistance gene is determined by inheritance of a major gene, that is, a quality trait, which is resistant to aphid, and is resistant to aphid. Oriented selection of synthetic raw materials under dominant mode: 1) selection of breeding, 2) cross breeding, 3) backcross breeding, seedlings of inbred lines cultivated above, selection of quality traits that are compatible with worms that are not parasitic and resistant to adaptation For the four quality traits of sexuality, concealment period, and ecological compensation, distant hybridization is conducted to obtain the hybrid seed of the inbred maize inbred line of the present invention. The advantages of the present invention are that: the problem of anti-mite of corn seeds is fundamentally solved, the incidence of the generation of mites is reduced from the original 93% to about 5%, and some good inbred lines have reached the degree of immunity and improved the corn The production of pesticides avoids the use of pesticides, controls the residual pesticides in corn, and meets the standards of green crops.
6. Breeding of high-yield waxy corn and selection and preparation of hybrids
Application (Patent) No.3
Abstract: The present invention proposes a method for breeding and compounding high-yielding waxy corn, characterized in that a sterile hybrid and a fertile hybrid are planted in a field planting or mixed planting; the sterile hybrid is passed 1 sterile gene transfer; 2 backcross; 3 continuous backcross; 4 homozygous sterile hybrid combinations; The production of waxy maize hybrids produced by this method is 14% to 22.88% higher than that of the original conventional maize single crossbreeding. It only requires the development of male sterile lines, does not require the cultivation of restorer lines, simplifies the maize breeding program, saves time, Labor saving.
7. Method for cultivating spring maize in mountain areas
Application (Patent) No. 6
Abstract: The present invention discloses a method for cultivating spring maize in mountain areas. The present invention aims at the main problems in the production of corn in Wuling mountainous areas. The five varieties of corn are highly productive, including variety, sowing date, density, plastic film mulching, mulching, transplanting and fertilizing. Starting from the key links, through experimental research and demonstration applications, we present the latest varieties suitable for high-yield, grain-fed, and high-yield varieties that are suitable for use in late-maturity, medium-late and late-maturing Wuling mountainous regions, large spikes, and medium and large panicles. Sowing, plastic film mulching and mulching seedlings transplanting, rational close planting, increased organic fertilizer, rational management of chemical fertilizers, make up the application of fertilizer and other technical measures, to achieve a high yield of corn. The technology of the invention is simple and easy to be accepted by farmers and is suitable for application by corn seed companies and agricultural technology promotion and related departments at various levels in the Wuling mountainous area, and has an excellent promotion for guiding the corn production in mountainous areas, substantially increasing the yield per unit of corn, and solving poverty and poverty in mountainous areas in poverty.
