Significance and methods of thinning male flowers (male flowers) in walnut trees
The number of male flowers of walnut is large, which far exceeds the need for pollination, and the development of male flower buds needs to consume a lot of water, sugars, amino acids and so on. Removing too many male flower buds from walnut trees is called sparse male. Thinning male flowers can save a lot of water and nutrients for the development of female flowers.

Measures to prevent Frost in flowering period of Walnut Fruit trees
The main results are as follows: 1. To select suitable garden plots and varieties, we should refer to the results of local agroclimatic regionalization, reasonably carry out industrial layout, and select favorable terrain which is not conducive to air-conditioning accumulation to avoid the harm of low temperature and frost. In general, cold air in valleys or depressions is easy to gather, often causing frost, so

Remedial measures after Frost damage
1. Carry out artificial pollination in time if the late frost occurs early and the temperature drops below 0 °C, the flowers that are blooming or have been blooming are seriously injured by low temperature and have lost the ability of pollination, fertilization and fruit set. at this time, the unopened mid-and late-stage flowers should be treated after frost.

Basic characteristics of soil in High-yielding Orchard
Soil is the basis for fruit trees to survive. The soil of high-yield orchard generally has the following characteristics: deep soil layer, loose soil, living soil layer with a certain thickness (more than 60 cm), high content of soil organic matter, strong ability of water retention and fertilizer supply. Walnut belongs to deep-rooted tree.

Deep turning and soil improvement technology of walnut orchard
Deep tillage is one of the main technical measures for improving soil in walnut orchard, which is suitable for areas with poor soil conditions. Through deep ploughing, on the one hand, it can play the role of storing water and preserving moisture and improving soil structure; on the other hand, it can enhance the activity of soil microorganisms and accelerate the speed.

Nutrients needed for the growth and development of walnut fruit trees
The growth and development of fruit trees need two kinds of nutrients: one is organic nutrients, including amino acids, proteins, sugars and phospholipids, which account for 90% ~ 95% of the total dry matter, all of which are synthesized directly or indirectly by photosynthesis. it can be seen that photosynthesis is the fruit.

Characteristics of Fertilizer requirement for growth and Development of Walnut trees
Walnuts like fertilizer, but the fertilizer requirements are different in different age periods and different phenological periods. The fertilizer requirement of walnut is different in different ages. The ontogeny of walnut trees can be divided into four stages: young stage, early fruiting stage, full fruiting stage and aging stage. Infancy period

Cactus reproduction
When it comes to reproduction, we must make a clear distinction between asexual reproduction by cutting or grafting and sexual reproduction by seed.

Manifestations of deficiency and toxicosis of walnut
The key to scientific fertilization is to accurately judge the surplus and deficiency of nutrient elements and tree nutrients in the soil. The basis of fertilization includes morphological diagnosis and nutrition diagnosis. Morphological diagnosis is to preliminarily judge the amount of nutrient elements according to the external morphological characteristics of fruit trees.
