Embodiment 1

[0032] On August 6th, 2010, the inventor was in Ningwu Town, Wuming County, Guangxi, using vertical spiral rotary grinding drill bit mechanical powder ridge land preparation and tractor rotary tillage land preparation (contrast), to test, sowing on August 6, the variety is Guihan No. 3, surveyed on August 20, the results showed that the plant height of rice planted in Fenlong increased by 0.3%, the root length increased by 61.77%, and the number of leaves increased by 3.93%. This test shows that the rice cultivated in Fenlong has a particularly well-developed root system, more fibrous roots, strong plants, and erect leaves (see figure 1 ).

Embodiment 2

[0034] Around April 10, 2011, the inventor transplanted super rice, the variety Y Liangyou No. On May 9, we invited several experts from the Guangxi Academy of Agricultural Sciences to investigate. Intuitively, the growth of super rice planted in Fenlong plots is obviously better than that of ordinary tractor plots. The number of tillering seedlings reaches about 360,000 in 26 days of super rice powder ridge cultivation and throwing (transplanting) seedlings, and the root system is as large as 2 figure 2 shown. Experts believe that there are several characteristics of super rice powder ridge cultivation performance: 1. The root system continues to grow vigorously and has many white roots. 2. After the paddy field is exposed to the sun, the thickness of the loose soil in the plowing layer is mostly 20-25 cm, which is about 8 cm thicker than the conventional one; the field surface does not crack, the soil is like a sponge, and the performance of water and fertilizer retention ...

Embodiment 3

[0036] On May 4th, 2011, the inventor was still at the super rice test demonstration base in Fumian District, Yulin City, (next door to the field of Example 1) using auger bits to mechanically enter the soil and vertically rotate the soil to form a ridge naturally, and enter the soil to rotate The grinding depth is about 25 cm, ensure that it is screwed to the raw soil layer, and the soil powder ridge is finely crushed, deeply loosened without disturbing the soil layer, and the crushed soil naturally floats about 5-7 cm. 60-300 cm, the irrigation and drainage ditch between the box and the box, the bottom of the ditch is 20-30 cm, and the width of the ditch is 15-25 cm. For direct seeding cultivation, apply fertilizer on the box surface and mix it with the soil. For rice seeds, brush the topsoil slightly with a bamboo rake to cover the rice seeds with soil, keep the soil at a certain humidity before emergence, artificially irrigate after emergence or use natural precipitation, a...

Abstract

The invention discloses a crushing and ridging culture method of rice. The method comprises the following steps that: a spiral bit machine is adopted to vertically mill the soil in a rotary manner to naturally form beds and ridges, the rotary milling depth in the soil is 20-30cm, the spiral bit machine is ensured to rotate till the raw soil layer and crush the soil into fine powder and ridge the soil, the crushed soil naturally floats upwards about 5-10cm, the soil is deeply loosened and the soil layer is not disturbed, the bed width ranges from 60cm to 300cm depending on the number of the crushing and ridging mechanical bit devices, irrigation and drainage ditches are formed between the beds, the no-tillage depth of the ditch bottoms is 20-30cm and the ditch width is 15-25cm; then directly seeding or seedling throwing or seedling transplanting after water return is carried out on the crushed and ridged fields; and the field moisture alternates between wetting and drying. The method has the following advantages: the traditional mode of directly seeding dry rice after harrowing the whole field with ploughs and transplanting (throwing) seedlings of rice after harrowing the field with ploughs is changed; the soil is fine and loose, has deeper active layer, stores and retains water, has sufficient oxygen, is beneficial to quick rooting and more roots, improves the drought, insect pest and lodging resistance, uses water to regulate atmosphere, fertilizers and growth, can meet the requirements of high yield, growth and development of rice for water, atmosphere and nutrients and improves the yield and quality of rice.

Description

technical field [0001] The invention relates to a tillage and cultivation method for crops, in particular to a tillage and cultivation method for rice. Background technique [0002] Rice is one of the most important food crops for people. For thousands of years, humans have developed a set of mature farming methods for rice planting, from soil preparation, seed selection, seedling raising, transplanting, intertillage and weeding, fertilization to harvesting. There is a lot of experience for reference in practice, and it seems that there is no need for research. From the ancient records of the past dynasties, people have long recognized that rice cultivation methods have a very important and inevitable relationship with its high-quality and high-yield growth. The substitute field method and the district field method are farming forms that adapt to the land continuous cropping system. In order to facilitate the restoration of soil fertility, the substitute field system has cha...
