In recent years, China's agricultural technology has become more and more developed, and many new planting methods have emerged in some areas, which have improved economic benefits and output. Let's take a look at the annual production of rice, rice-sweet corn, in Xinhui District, Jiangmen City. Three new crop cultivation models.
First, the specific approach
In 2017, a 0.3 hm 2 test field was selected in the test base of Qibao Miaobian Village in Huicheng, Xinhui District. Early-stage selection of late-maturing rice varieties double yellow silk seedlings was planted, planted on February 28, transplanted on March 17, July. Harvested on the 2nd, the output per 667 m 2 was 453 kg. The late-growing selection of local varieties, Yu Nong, was planted, planted on July 19, transplanted on August 2, and harvested on October 25, with a yield of 402 kg per 667 m 2 .
The sweet corn variety Zhuyutian No.1 was selected, and the seedlings were started early on October 14th. There were 35 seedling trays of 100 holes per 667 m 2 , and the cost of adding the nutrient substrate to each seedling tray was 2.2 yuan. When planting, first arrange the seedling tray, install a half cup of the substrate, then sow the single grain, cover the substrate after sowing, and pour enough water to cover the black gauze or film according to the weather and the humidity of the nutrient substrate. After 2~3 days, some seeds have sprouted, and the black gauze is arched. The number of watering is determined according to the weather and the humidity of the nutrient soil. When the seedlings grow to 2 to 3 leaves, they gradually refine the seedlings for 2 to 3 days. On October 26, the seedlings have grown to 3 to 4 leaves. After the late corn harvest, the horses were irrigated on October 31, and then drained immediately. They were transplanted on November 2, when the corn seedlings had grown to 5-6 leaves. When using the special iron cone for measuring the seedlings (the iron cone for vertical measurement at the construction site, the size is larger than the hole of the tray, and then welded with the water tube of about 1.2 m), the hole is opened according to the planned plant spacing, one per hole, 1 of which /4 area with a line spacing of 60 cm, plant spacing of 20 cm, planting about 4 800 plants per 667 m 2; 3/4 area with a line spacing of 60 cm, plant spacing of 30 cm, planting about 3 per 667 m 2 200 strains. The drainage ditch was excavated on the 2nd day after transplantation, but at 4 points, the terrain was slightly lower and the accumulated water was not completely drained.
On the 3rd day after the maize transplant, the new root system began to grow, and 10 kg of compound fertilizer (25-7-18) was applied per 667 m 2 ; the tassel was started on December 6, and the above compound fertilizer was applied every 667 m 2 . Kg. In the middle and late period, the horse water was irrigated twice according to the weather changes and the actual water conditions in the field, and was drained immediately after each irrigation. One day after 15 days of transplantation, the heartworm was protected.
In order to ensure the yield and quality after pollination, only the top one fresh oyster is generally left. The other fresh oysters are removed after the first fresh oyster pollination and the second fresh oysters have been removed (commonly known as corn cultivars). The test was chosen to be carried out in clear, dry weather to reduce injury and promote wound healing. When picking the corn, hold the plant in the left hand, grab the top of the corn in the right hand, and remove it from the side.
Second, the test results
1) Maize plants have different time of tasseling. They were firstly bred on December 6th, and at the latest on December 21st. At the end of the harvest, the plants with poor sensation were poor. 2) Plants with a planting size of 60 cm × 30 cm have better growth than plants with a planting size of 60 cm × 20 cm, and the heads are large. The former has an average weight of 0.59 kg and a price of 5 kg for 1 kg. 0.25 kg, grain plumpness and appearance quality are poor, 1 kg price is 2 yuan. 3) Plants with low water and low water have poor growth and small heads. 4) After transplantation and harvested on February 12, the whole plant population only had a few small spotted diseases and individual dwarf diseases. About 100 strains were bitten off from the base by the underground pests after transplanting and before the tasseling, and the other pests were less. 5) From February 5th to 9th, in the low temperature and rainy weather of 4～5 °C, some plants showed different degrees of freezing damage.
Third, related experience and recommendations
3.1 Related experience
1) The sowing date of early-growing rice varieties can be appropriately moved forward for 5-6 days according to the actual weather conditions, that is, planted around February 22-23; late planting should also be planted before July 10, and strive for October 20th. Harvest, harvest the horse water and drain it after harvesting, then hurry to transplant, increase the effective accumulated temperature for the winter sweet corn, and arrange the flowering and silk pollination growth stage in early December. Both are above 16 °C, and the rain is small, the light is sufficient, and the pollination is suitable for improving the success rate of planting. 2) Use varieties with better cold tolerance as much as possible to ensure that the leaves of the corn are not damaged by freezing during the late filling stage, and improve the grain plumpness and commodity quality.
3.2 Related recommendations
1) The seedling time of sweet corn varieties should be determined according to the specific prediction time of late rice harvesting. The seedlings should be raised about 12 days earlier, and the corn seedlings should be transplanted best in 3~4 leaves. 2) Planting size should be 60 cm × 30 cm, and about 3 200 plants per 667 m 2 plant. When transplanting, pay attention to making the growth direction of the corn leaves consistent and perpendicular to the row direction. This can ensure that the light receiving postures of the leaves are consistent, do not overlap each other, and are easy to manage. 3) After the corn transplant, the drainage ditch should be excavated as soon as possible, and one drainage ditch should be excavated every 8 rows. The two rows of the reserved ditch should be about 1 m wide. The drain is about 20 cm wide and 15 cm deep. If there is a place with a slightly lower terrain and easy to accumulate water in the field, it is necessary to properly open the small ditch to attract water, so as to ensure the same population growth. 4) The first fertilization after corn seedling transplanting new roots should be applied with freshwater fertilizer, which is conducive to promoting the uniform growth of roots and populations. 5) After 2 to 3 days of corn seedling transplantation, 40% zinc sulphur phosphorus is mixed with fine sand and evenly spread on the ground pests such as tigers, mites and armyworms.
Fourth, the conclusion
After the late harvest, the rice straw will return to the field, and the winter sweet corn will be used to moisturize the corn field, prevent weeds, increase soil organic matter, and solve the pollution problem caused by burning straw. At the same time, due to low temperature in winter, low humidity, less pests and diseases, less pesticides, green products, high market prices and considerable economic benefits, an attempt was made to produce three new crops per year, with the aim of exploring the full use of winter leisure. Tian and favorable light and temperature resources, through the winter maize to increase the total grain output, through the 2017 experiment, obtained valuable data and lessons, providing a useful reference for the 2018 planting trial.
