Peanut 60 cm small ridge double-row single-seed equidistant planting method and special double-row single-seed planter

Abstract

The invention relates to a 60-cm micro-ridge double-row single-grain equidistant planting method for peanuts and a special double-row simple-grain sower. The planting method includes the following steps of selecting a land, selecting seeds, pretreating the seeds before sowing, conducting sowing, applying fertilizer, spraying herbicide, clearing soil around peanut seedlings, conducting intertillage, spraying foliage fertilizer and fungicide, conducting watering in time in case of drought and carrying out harvesting and airing. An existing double-grain or multi-grain sowing mode is changed into the single-grain sowing mode to achieve the effects of saving cost and increasing the yield and incomes. Micro-ridge double-row planting is adopted in the planting method, the existing ridge width is not changed, peasants accept the method more easily, and the land use ratio is increased. A soil dividing and blocking plate and a soil dividing location plate are additionally arranged on a furrow opener, and a double-seedling-hole seed limiter is additionally arranged on a seed-metering device. The sower ensures that the plant spacing and row spacing after the peanut seeds fall on a seedbed are accurate. The seed putting height of the sower is limited by the double-seedling-hole seed limiter, so that the peanut seeds accurately fall on the seedbed, and seed upspring and rolling after falling on the land due to mechanical forward speed inertia are reduced.

Description

technical field [0001] The invention relates to a peanut planting method and a peanut planter, in particular to a method for planting peanuts in small ridges with double rows and single grain equidistant and a special double row single grain planter. Background technique [0002] Peanuts have high nutritional value and are rich in fat and protein. In particular, it contains essential amino acids for the human body, which can promote the development of brain cells and enhance memory. Also known as "longevity fruit", it nourishes and nourishes and prolongs life. Peanut oil is a non-drying oil with a light yellow color, good transparency, and a delicious fragrance. It is an excellent cooking oil. [0003] At present, the following problems exist in the cultivation of peanuts in the northeast of my country, resulting in low peanut production. First, inspired by the use of large ridges (85-90 cm) for double-row film-covered planting of peanuts in Shandong and other places, we ...

Problems solved by technology

[0003] At present, the following problems exist in the cultivation of peanuts in the northeast of my country, resulting in low peanut production

First, inspired by the use of large ridges (85-90 cm) for double-row film-covered planting of peanuts in Shandong and other places, we promoted the planting of peanuts in large ridges and double-row film-covered machinery in 2004. The pitch is all 1.2 meters, and there are very few variable-pitch agricultural four-wheels. There is a problem that the agricultural four-wheels do not match the seeder, resulting in a large double-row ridge spacing that is too wide, reaching 1.1-1.2 meters. In the autumn of that year, we and Shandong Ping Peanut expert Cai Jiujiu conducted field investigations in Yishun Village, Hongqi Town, Shuangliao City, and planted Luhua No. 11 film-coated large peanut variety with a ridge spacing of 85 cm and 12,900 holes for seedlings. 5100 points, yield 5105 catties, 128% increase...

Due to the small number of planting plants per unit area, low yield, and the strong wind and sand in Shuangliao and the western part of our province, the film-covered peanut film is easily damaged

In addition, farmers in Northeast China have always used small ridges (that is, 60 cm) for planting. Therefore, it is impossible to promote large-scale peanut double-row film-covered mechanical planting technology on a large scale.

Second, the existing farmers who plant peanuts are cultivating on the ridge platform to form a pointed ridge, so that some fruit needles cannot enter the soil, and the fruit needles can only hang on the side of the ridge, but cannot result in no effect, resulting in a serious reduction in production.

Peanut needles can only bear fruit on a flat ridge. The lower needles of the peanut plant enter the soil first, and the needles at high nodes enter the soil later. However, the needles buried in the soil must be on the same level to bear fruit, which requires a flat ridge. However, once the soil is filled on the ridge platform, the ridge surface will be uneven, causing some fruit needles to fail to enter the soil, resulting in reduced production

Third, most of the existing peanuts are planted with double seeds and multiple seeds, which not only wastes seeds but also is not drought-tolerant, and the yield is low

The 4th, the seedbed opener of existing peanut planter is simple double disk opener, and original disc type seeder opener can not carry out mechanically to the seedbed of 100mm width in the middle of double seedling eye seedbed. treatment, and the surface of the seed bed is uneven and the soil density is small and unreal. The soil quality of the seed bed is xuan soil, which is not conducive to the germination of peanut seeds and the expansion and development of the root system, thereby affecting the germination, rooting, and fruiting of peanut seeds, and affecting peanuts. increase in production

Fifth, the distance between the seeding opening of the existing peanut planter and the peanut seed bed is relatively high, which is susceptible to the impact of inconsistent inertia of the discharged seeds and the slope of the land caused by the change of the forward speed of the machine during the forward process, causing the seeds to fall behind the seed bed The position is not accurate, resulting in uneven seed density, affecting the increase in peanut yield
