Corn-horse root three-dimensional high-efficiency cultivation technology
First, the basic situation
The horseradish has a longer growth period in this model. It uses the favorable conditions of small growth in the early stage of horseradish and large vacant field. The corn is interplanted in the early stage of horseradish, and the horseradish enters the growth peak after corn harvesting. The model utilizes the short growth period of corn, and the corn and horseradish interplanting make full use of the complementarity of natural space and season to achieve efficient interplanting and achieve better economic benefits.
Second, technical points
(1) Variety selection. Maize chooses varieties with shorter growth period, such as Suyu No. 10.
(2) Scientific fertilization. Corn horseradish has a long symbiotic period, requires a large amount of fertilizer, and horseradish is resistant to fertilizer, so the base fertilizer should be adequately applied. After the corn is harvested, the horseradish should be applied 20-30kg of compound fertilizer in time to promote the later growth.
(3) Control pests and diseases. It is necessary to prevent night moth pests, white rust and aphids in time.
(4) Timely harvest. After the corn is mature, it will be harvested in time, and after the field is removed from the field, it will make room for the growth of horseradish. After mid-November, after the first thick frost, the upper leaves begin to harvest when they are yellow and aging, and the premature harvest is not enough. Pay attention to timely sales after harvesting. If you need to store, you should pay attention to antifreeze.
Third, the typical case
Take Xiangxi Village, Nanyang Town, Dafeng District as an example. Corn and horseradish are sown in the spring of April. 1 row of corn and 1 row of horseradish per 1 vacant. Corn and horseradish line spacing is 1 meter, corn 1 hole 2 plants, hole distance 25 cm, density 4500-5000 plants/mu, horseradish cultivation planting root 30kg, corn harvest from late July to early August, horseradish Harvested from the end of November to the beginning of December. The output of corn is about 600 kg, the output value is 1080 yuan; the output of horseradish is 750 kg, the output value is 2,250 yuan; the net income of mu is 2,540 yuan. In the conventional wheat-summer corn model, the yield of wheat is 475 kg, the yield of corn is 500 kg, the output value is 2040 yuan, the net income is 1360 yuan, and the corn-horse root has an added benefit of 1180 yuan per mu.
The auger bit adds a long deep spiral flute for effective chip removal.
Two styles of auger bit are commonly used in hand braces: the Jennings or Jennings-pattern bit has a self-feeding screw tip, two spurs and two radial cutting edges. This bit has a double flute starting from the cutting edges, and extending several inches up the shank of the bit, for waste removal.
The Irwin or solid-center auger bit is similar, the only difference being that one of the cutting edges has only a "vestigal flute" supporting it, which extends only about 1â„2 in (13 mm) up the shank before ending.
The diameter of auger bits for hand braces is commonly expressed by a single number, indicating the size in 16ths of an inch. For example, #4 is 4/16 or 1/4 in (6 mm), #6 is 6/16 or 3/8 in (9 mm), #9 is 9/16 in (14 mm), and #16 is 16/16 or 1 in (25 mm). Sets commonly consist of #4-16 or #4-10 bits.
