Coastal mud flat asparagus seedling cultivation and planting method

Abstract

The invention discloses a coastal mud flat asparagus seedling cultivation and planting method. The method particularly comprises the steps of (a) germination acceleration, wherein from February to April that year, asparagus seeds are soaked in warm water and then taken out, germination acceleration is carried out on the seeds for 5-7 days, and the seeds can be sown when the sprouts of 10%-20% of the seeds come out; (b) seedling cultivation in a feeding block, wherein the seeds subjected to germination acceleration are sown in the feeding block mixed with salt-tolerant water-retaining agents, and after the seedlings grow to be as high as 30-40 cm and 3-4 branches grow from each seedling, the seedlings can be planted; (c) rest-balk making and planting, wherein a flat field with the salinity-alkalinity lower than 0.7% is selected and is deeply ploughed for 30 cm, organic fertilizer is applied, rest-balks are made after rotary tillage, the width of each rest-balk is 80 cm, the height of each rest-balk is 30 cm, the intervals between the rest balks are 60 cm, each rest-balk includes one row, the depth of each cave is 15 cm, the plant row spacing is 25 cm, and 0.2 g of salt-tolerant water-retaining agents are evenly scattered in each cave; and (d) regular management on the planted asparagus. The coastal mud flat asparagus seedling cultivation and planting method can reduce stress on the seedlings from salt and alkali and improve the survival rate of the asparagus, rainwater can be repeatedly stored by the water-retaining agents to be used by plants, growth needs of the asparagus are guaranteed, and the problems that the root systems of the asparagus seedlings are weak, and the survival rate of the asparagus seedlings in a coastal mud flat is low are resolved.

Description

technical field [0001] The invention relates to the field of agricultural cultivation, in particular to a method for growing and planting asparagus in coastal beaches. Background technique [0002] The total area of ​​tidal flats in my country is 3.538 million hectares. In addition, the annual sedimentation area is about 30,000 hectares. It is an important reserve land resource with large area, concentrated distribution, good location conditions, and great potential for comprehensive development of agriculture, animal husbandry and fishery. However, especially the newly reclaimed tidal flats have high salinity, which is not suitable for the growth of most crops and has become a "paradise" for mariculture, which makes it difficult for the country to realize the country's desire to reclaim land. [0003] The tidal flats after reclamation are all saline-alkali land, which needs a lot of fresh water to be washed for many years before they can be used for planting. The salt tole...

Problems solved by technology

[0005] The purpose of the invention is to: in view of the fact that asparagus is not easy to survive in the mid-salinity soil without fresh water irrigation on the coastal beach, a salt-tolerant water-retaining agent is placed in the nutrient bowl substrate and the planting hole to provide water supply for the asparagus after planting and reduce the harm of saline-alkali stress. Improve the survival rate of asparagus cultivation, promote the healthy growth of asparagus roots and plants, and lay the foundation for high-quality and high-yield asparagus in the future
