example 1

[0037] Site selection and soil preparation: For rhubarb planting, choose sandy loam with good drainage or plots containing humus loam. Plow more than 33 cm deep, raking thinly to remove grass roots and stones, and make the soil loose and level. Maize is planted at equal row spacing. First, dig a 10cm deep and shallow ditch on the ridge core 80cm according to the ridge core. Sprinkle 2500~4500 kg of decomposed manure in the furrow, and then apply NPK ternary compound fertilizer 50~60kg / mu, and add 1.5~ zinc fertilizer. 2kg / mu. Then take soil between the two ridges and cover them on the fertilizing ditch to make a ridge with a width of 0.5 m and a height of 0.30 to 0.40 cm, and then cover with mulch to prepare for transplanting.

[0038] Corn nutrient block (or plate) seedling cultivation: sowing in early April, covering with film after sowing, smelting the seedlings 2 to 3 days before planting, and adding fertilizer with dilute manure water.

[0039] Corn mulching cultivation: a) ...

example 2

[0044] Site selection and site preparation: Same as Example 1.

[0045] Corn nutrient block (or plate) seedling cultivation: same as Example 1.

[0046] Corn mulching cultivation: Same as Example 1.

[0047] Palm leaf rhubarb seedlings: a) seedlings: sowing in autumn. The method is to sow, spread the seeds evenly on the border surface. There is 1 seed every 2 to 3 cm. After sowing, cover with fine soil to cover the seeds. Finally, cover the border with grass. The amount of seed per mu is 2 to 4 kg. If the soil is dry, plant the seeds after watering the border 3 to 4 days before planting to ensure smooth germination of the seeds. b) Seedling management: Same as Example 1.

[0048] Transplanting Rhubarb palm leaves: a) Transplanting time: in the middle of March of the third year. b) Method of taking seedlings: same as Example 1. c) Planting density: Same as Example 1.

[0049] Other management is the same as in Example 1.

example 3

[0051] Site selection and soil preparation: For rhubarb planting, choose sandy loam with good drainage or plots containing humus loam. Plow more than 33 cm deep, raking thinly to remove grass roots and stones, and make the soil loose and level. Plant according to the width and narrow rows, first dig a 10cm deep and shallow furrow on the ridge core 180cm according to the ridge core, sprinkle 1500~2500 kg of decomposed manure in the furrow, and then apply NPK ternary compound fertilizer 40~50kg / mu, and add zinc fertilizer 1.5~2kg / mu. Then take soil from both sides of the ditch and cover it on the fertilizing ditch to make a ridge with a width of 0.3m and a height of 0.30 to 0.40 cm. The width of both sides of the ridge is 0.25m, and the middle is a reserved row of 1.0m. Then cover the ridges with mulch to prepare corn for transplanting.

Abstract

The invention relates to a relay intercropping method for rheum palmatum and corn. The relay intercropping method for the rheum palmatum and the corn is characterized by comprising the following operating steps: (1) selection and preparation of land; (2)corn nutritive cube or tray seedling;(3) corn plastic film mulching cultivation; (4) culture of rheum palmatumseedling; (5) rheum palmatum transplantation; and (6) rheum palmatum field management. Compared with the prior art, the relay intercropping method for the rheum palmatum and the corn has the advantages that rheum palmatum and high-stem crop corn relay intercropping is enabled to artificially create a damp environment where is beneficial to the growth of the rheum palmatum and the high-stem crop corn, the growth of the rheum palmatum is benefited, and output and quality of the rheum palmatum can be improved. Furthermore, temperature, light, water and land resources are fully utilized. Grain yield can be increased by two seasons in an equal area on the premise that planting density and output of the rheum palmatum are not reduced, the contradiction that grain crops and medicinal crops contend the land is effectively alleviated, and economic benefit is drastically improved. In addition, relay intercropping method for the rheum palmatum and the corn has the advantages of being easy and convenient to operate, capable of saving cost and easy to popularize.

Description

Technical field [0001] The invention relates to a method for intercropping rhubarb and corn. Background technique [0002] Rheum palmatum is a rhubarb plant of the genus Polygonaceae, Latin name: Rheum palmatum L., with dry roots and rhizomes. Chinese medicine name: Rhubarb [Radix Et Rhizoma Rhei]. Alias: horseshoe rhubarb. It is a commonly used and bulk medicinal material, and it is also one of the world-famous important medicinal materials of our country. Rhubarb is still a good medicine to relieve extremity heat, relieve stool, detoxify stagnation, and lower blood stasis. It is Rhubarb Qingwei Pill, Niuhuang Shangqing Pill, Niuhuang Qinghuo Pill, Niuhuang Jiedu Pill, Baishun Pill, Qingning Pill, and Huanglian Shang It is an important raw material for dozens of Chinese patent medicines, such as Qingwan and Huanglianqingweiwan. At present, low-alcohol rhubarb wine, rhubarb beverages, and rhubarb diet pills are very popular in the market. For a long time, in addition to dome...
