Problems solved by technology

The irrigation measures of this method are mainly artificial spraying water or sprinkler irrigation, and the fertilizer management is artificially spreading urea, applying compound fertilizer to plants or spraying foliage fertilizer, etc., which will easily cause waste of water and fertilizer resources.
With the reduction of labor and the increase of labor costs, it is bound to affect the cost of raising seedlings

Embodiment 1

[0019] The rubber saplings used in this example are the budding seedlings of Reyan 7-33-97 which survived budding.

[0020] The seedling-raising container used in the present embodiment is the cylindrical seedling-raising container of independent design, and its upper inner diameter is 6cm, and height is 35cm, and the bottom inner diameter is 2cm.

[0021] Coconut peat, farmland topsoil and manure are evenly mixed according to the volume ratio of 1:1:0.3 as the cultivation substrate. In the greenhouse, place the funnel-shaped containers filled with the above-mentioned culture substrates vertically on the supports and make the bottom of the cylindrical containers more than 4cm away from the ground. The supports are arranged in wide and narrow rows in the greenhouse for seedling cultivation. Budding live rubber tree seedlings are transplanted in the culture substrate in the funnel-shaped container. During the non-fertilization period, use the self-designed drip irrigation devic...

Embodiment 2

[0028] The rubber saplings used in the present embodiment and the container for growing seedlings are the same as in Embodiment 1.

[0029] Coconut peat, farmland topsoil and manure are evenly mixed according to the volume ratio of 1:1:0.3 as the cultivation substrate. In the greenhouse, the cylindrical seedling-raising containers filled with the above-mentioned culture medium are placed vertically on the supports respectively, and the bottom of the containers is more than 6cm away from the ground, and the supports are arranged in the seedling-raising greenhouse in the form of wide and narrow rows. The rubber tree seedlings that survived budding are transplanted in the culture substrate in the cylindrical seedling-raising container. During the non-fertilization period, use the self-designed drip irrigation device to drip clear water once every morning through the water inlet device, filter, drip irrigation pipe, dripper, etc., to keep the culture medium in the cup moist and ke...

Abstract

The invention relates to the technical field of cultivation of forest tree seedlings, in particular to a water and fertilizer management method for a rubber tree container seedling. The method comprises the following steps: uniformly mixing coco coir, farmland topsoil and farmyard manure as a cultivation substrate to be put into a seedling raising container; vertically placing the seedling raising container on a bracket, getting the bottom of the seedling raising container away from the ground, and transplanting the rubber tree seedling; irrigating the rubber tree seedling with clear water once through drip irrigation to keep the water mass fraction of the cultivation substrate above 80 percent; irrigating water and a fertilizer once every 2-15 days through drip irrigation, wherein the amount of the fertilizer applied for each plant is 30-60 ml of farmyard biogas slurry manure or 0.5-1 g of a compound fertilizer, and the nutrition supply of the plant is guaranteed until to out-planting of the rubber tree seedling. The method is suitable for cultivating full stands with complete developed root systems and longer main roots; the problems of more labor for seedling raising of the container seedling, waste of water and fertilizer, low planting survival rate and the like for a long time are solved.

Description

technical field [0001] The invention relates to the technical field of tree nursery stock cultivation, in particular to a water and fertilizer management method for rubber tree container seedlings. Background technique [0002] Rubber tree container seedlings (bag seedlings, bag seedlings, seed bag seedlings, small tube seedlings, etc.) are the main planting materials for rubber plantation renewal. The corresponding cultivation method is to place the nutrient bag filled with the culture medium on the ground, and regularly perform daily management such as watering, fertilizing, and weeding until it grows into 2 canopies with complete leaf canopies (stable period). The irrigation measures of this method are mainly artificial spraying water or sprinkler irrigation, and the fertilizer management is artificially spreading urea, plant compound fertilizer or spraying foliage fertilizer, etc., which easily causes waste of water and fertilizer resources. With the reduction of labor ...
